Journal of Orthoptera Research 28(2): 167-180. https://doi.org/10.3897/ jor.28.34605 Abstract The genus Lamellitettigodes Ginther, 1939 from Southeast Asia is re- viewed. The genus currently includes seven species and is transferred to Tetriginae Rambur, 1838. Two new species are described: Lamellitettigodes novaeguineae sp. nov. from New Guinea and Lamellitettigodes karwinkeli sp. nov. from Yunnan, People’s Republic of China. Lamellitettigodes palawani- cus Gunther, 1939 stat. nov. is no longer regarded as a subspecies of L. contractus, but a separate species. Two species are transferred from Eupara- tettix Hancock, 1904 to Lamellitettigodes: Lamellitettigodes sagittatus (Bolivar, 1887) comb. nov. and Lamellitettigodes cultratus (Bolivar, 1898) comb. nov. One species is transferred from Tetrix Latreille, 1802 to Lamellitettigodes - Lamellitettigodes signatus (Bolivar, 1887) comb. nov. Xistra tricristata suma- trana Bolivar, 1898 syn. nov., Xistra tricristata Bolivar, 1898 syn. nov., and Probolotettix corticolus Blackith & Blackith, 1987 syn. nov. are synonymized with Lamellitettigodes contractus (Bolivar, 1887). Probolotettix kevani Black- ith & Blackith, 1987 syn. nov. is synonymized with Euparatettix personatus (Bolivar, 1887). Additionally, in the genus Lamellitettix Hancock, 1904, Lamellitettix acutus Hancock, 1904 stat. rev. is retransferred from a subspe- cies of Lamellitettix gallinaceus (Stal, 1877) to a separate species status. Keywords China, fauna, Metrodorinae, New Guinea, Southeast Asia, synonymy Introduction At the end of August 2019, there were 2031 known Tetrigi- dae species worldwide (Cigliano et al. 2019). They occur on all the continents and inhabit almost all climatic zones from taiga to rainforests (Tumbrinck and Skejo 2017). Tetrigidae can easily be identified by their pronotum, which typically extends far over the body. This feature is clearly unique and proves the allocation of the species without doubt. Since 2014, the Tetrigidae of New Guinea has been revised in several papers (Tumbrinck 2014a, b, 2015, 2018, Tumbrinck and Skejo 2017). At the beginning of the revision, 67 species were known from New Guinea and the adja- cent islands Aru, Biak, Waigeo, and Yapen. With the genus Lamel- litettigodes, another genus is comprehensively revised within the context of the ongoing revision of the Tetrigidae of New Guinea. The genus was established by Giinther (1939) and comprised two species with three subspecies. After 1939, for the first time the ge- nus is fundamentally revised. With the addition of a new species described in this paper, there are currently 145 species known for New Guinea and the adjacent islands. Material and methods All specimens originate from the collections of several mu- seums. Various cameras using various lenses were used to take photos, all in macro mode by using a stacking system with an integrated scale bar or with a macro lens and millimeter paper. No post-processing of photographs was done. Millimeter paper was placed close to the photographed specimen and subsequently used to construct a scale bar, included in the photograph, after which the millimeter paper was deleted. The morphological ter- minology and measurement methods follow Tumbrinck (2014a) and good taxonomic practice suggested in Lehmann et al. (2017). For many localities, the geographical coordinates were identified as accurately as possible by localization of the place found on the labels with different gazetteers and extracted using the Google Earth program. These localities are presented in square brackets.

Results Taxonomy Genus Lamellitettigodes Giinther, 1939 Lamellitettigodes Giinther, 1939: 123; Yin et al. 1996: 878; Otte 1997: 46. Type species.—Paratettix contractus (Bolivar, 1887), by original designation. Taxonomic placement and justification.—Ginther (1939) assigned the genus Lamellitettigodes to the subfamily of Metrodorinae be- cause of the lateral lobes: they are almost, but not completely, at- tached as in Paratettix Bolivar, 1887. This was the main character used when the subfamily was established by Bolivar (1887), and Ginther also adopted it. Today, typically Metrodorinae are main- ly characterized by having the median ocellus and the antenna placed below the eyes, a relatively small divergence of the rami of the frontal costa not forming wide scutellum, and a similar length of the first and third segments of the hind tarsus (Pav6on- Gonzalo et al. 2012). Many species of Metrodorinae also exhibit the posterior angles of the lateral lobes of the pronotum produced outwards, often becoming acutely spinose. These characters taken together separate the subfamily from the other eight subfamilies J. TUMBRINCK of Tetrigidae, although no single character is enough to character- ize Metrodorinae by itself (Tumbrinck and Skejo 2017). In contrast to Metrodorinae, in Lamellitettigodes the antenna is inserted at the lower margin of the eyes, and the first segment of the hind tarsus is longer than the third segment. The similarity of Lamellitettigodes species with Paratettix and Euparatettix is clear when comparing all morphological characters from most of the Paratettix and Euparatettix species of Southeast Asia. Lamellitet- tigodes species have typical characters of Tetriginae: rounded lat- eral lobes of pronotum close to pronotum (directed downwards, slightly sidewards; this character is somewhat similar to Metrodor- inae), presence of posthumeral spots on the pronotum, L-shaped carinae of the vertex, pulvilli of the hind tarsus with apical teeth (absent in some Lamellitettigodes species), and hind wings exceed- ing the tip of the pronotum. Therefore, Lamellitettigodes is very close to Tetriginae and did not belong to Metrodorinae: I transfer this genus to the subfamily of Tetriginae. Description.—Gunther (1939) gave a detailed description of the genus, which is no longer applicable in some of its parts and must be amended. An improved redescription based on his description is presented here. Body of moderate size, slender. Head and pronotum smooth. Head and eye in lateral view not at all or slightly elevated above the pronotal discus. Antenna more than 1.5 times longer than fore femur, dorsal margin of antennal groove a little bit above the ventral margin of eye, between the eyes. Eyes small and in lateral view blunt and indistinctly conoidal. Antenna filiform, 14-seg- mented in male (including scapus and pedicel), 15-segmented in female. Fastigium of vertex in dorsal view as broad as or a lit- tle wider than the eye, fastigium in frontal view between the eyes slightly depressed. Fastigium in dorsal view with well-developed medial, lateral carinae, and fossula. Lateral carina clearly elevated, in lateral view weakly visible above the eyes and short, in dorsal view not converging towards the front, almost parallel, bending over at right angles to the medial carina (L-shaped). Transverse carina of the vertex in dorsal view slightly convex or straight. Fron- tal costa and facial carina in lateral view visible in front of eye (except in L. novaeguineae). Tip of fastigium and its frontal costa in lateral view protuberant. Facial carinae in lateral view concave in front of eye and slightly convex in front of antenna. Last seg- ments of maxillary palps not foliaceous. Anterior margin of pro- notum truncated. Pronotum slightly between shoulders. Prozonal carina and median carina clear, slightly elevated (lamellate in L. cultratus and L. novaeguineae), interhumeral carina absent, inter- nal lateral carinae not clearly visible. Pronotum behind shoulders weakly depressed on both sides of median carina and here very often provided with black spots (posthumeral spots) on each side. Lateral lobes broadly rounded, not as close to body as in Paratet- tix. Tegmen almost as long as the fore femur, rather broad and at the end broadly rounded. Macropterous and macropronotal. Alae clearly exceed the pronotum apex. Hind femora with very small antegenicular and especially genicular teeth, with some sharply tuberculate raised slants of their middle outer surface. Posterior tibia distally not or slightly widened, with a few small spines on upper edges. First segment of the hind tarsus not longer than the third, pulvilli acute, in three species with apical teeth (L. sagittatus, L. signatus, L. karwinkeli). The coloration is highly variable and not a useful feature for either generic or specific diagnosis (as reported for Tetriginae in Lehmann et al. 2017). JOURNAL OF ORTHOPTERA RESEARCH 2019, 28(2) J. TUMBRINCK Diagnosis.—The genus Lamellitettigodes is characterized by a protu- berant tip of fastigium and frontal costa (in lateral view); facial cari- nae in lateral view visible and clearly concave in front of eye and slightly convex in front of antenna. Only in L. novaeguineae is tip of pronotum not visible in lateral view, but present. Additional charac- ters for the genus are: 1) lateral carina of the vertex in frontal view clearly elevated as small fastigial horns, but in lateral view weakly visible above the eyes (Plate 5Q, R, V, W); 2) median carina continu- ous to the tip of the pronotum; 3) clearly keeled or lamellate median carina; and 4) keeled and more or less converging prozonal carinae. The genus is close to Euparatettix and Paratettix (see above). In the typical representatives of mentioned genera, the tip of the fas- tigium is not protruding, but more or less rounded. Also, frontal horns are absent. In Paratettix the median carina is absent in the frontal margin of pronotum. A similarity exists also with Lamel- litettix Hancock, 1904. The type species of the genus is Lamellitettix acutus Hancock, 1904 stat. nov. Blackith (1988) synonymized L. acutus and L. pluricarinatus Hancock, 1909 with Lamellitettix insularis (Bolivar, 1887), and L. insularis and L. fletcheri Hancock, 1915 with Lamellitettix gallinaceus (Stal, 1877) without giving evidence for the synonymy (Blackith 1992). Types of L. gallinaceus were examined by the author in NHRS and those of L. pluricarinatus in UMO. L. acutus and L. pluricarinatus are rather different from L. gallinaceus by the form of the pronotum, but it remains uncertain whether L. acutus and L. pluricarinatus are separate species. Further studies of the type of L. acutus and more specimens are needed. Lamellitettix, with its genotype L. acutus, is different from Lamellitettigodes by the tip of the fastigium which is, in lateral view, not protuberant, by the lateral carinae that are curved in dorsal view forward towards the medial carina and are not parallel, and by the lateral lobes that are acutely pointed sidewards. A similarity exists also to Xistra Bolivar, 1887 and Xistrella Bolivar, 1909. In the typical representatives of Xis- tra and Xistrella, the antenna is inserted in a considerable distance below the ventral margin of the eye. In Lamellitettigodes, the antenna is inserted as high as the ventral margin of the eye (Plate 5Q—X). Composition and distribution.—Altogether seven species are now as- signed to the genus Lamellitettigodes: one hitherto described spe- cies (widely distributed L. contractus from peninsular Malaysia, Singapore, Sumatra, Java, Borneo, Sulawesi, and Solomon Isl.) supplemented with a subspecies (L. c. palawanicus inhabiting Pal- awan archipelago of the Philippines) here elevated to the species level, two new combinations (widely distributed L. sagittatus from Vietnam, Thailand, peninsular Malaysia, Sumatra, Java, Borneo, Philippines, Moluccas Isl., Sulawesi, New Guinea, and Timor, and L. signatus from the Philippines) and two species described here as new to science (L. novaeguineae inhabiting SE New Guinea, and L. karwinkeli inhabiting Yunnan, PR China). One hitherto described species (L. sumatrana) and a subspecies (L. contractus tricristatus) are synonymized with L. contractus.

Notes.—Bolivar (1898) described the species under the section Metrodorae as belonging to Xistra, while earlier he described L. contractus within the section Tettigiae, assigned to the genus Para- tettix. The two sections were distinguished by morphology of the lateral lobes—projected sidewards in Metrodorae, directed down- wards in Tettigiae. When comparing types, I did not see differences in this feature. JOURNAL OF ORTHOPTERA RESEARCH 2019, 28(2) J. TUMBRINCK Gunther (1939) regarded L. contractus tricristatus as a subspe- cies of L. contractus, distinguished from the nominal by smaller size, sharper keeled prozonal carinae and, in lateral view, clearly visible fastigial horns (above the eyes). L. c. tricristatus should be slightly smaller and should have wavy margins of the fore legs (Gunther 1935). All these features are, however, in the range of variation of the species and are not of diagnostic value. Moreover, I did not find reported differences when comparing the types. Otte (1997) gave the specific status to the subspecies only with the rea- son of occurrence on different islands. All these data prove that L. tricristatus (Bolivar, 1898) is con- specific with L. contractus. Synonym Tetrix cuspidata Hancock, 1907 Notes.—Ginther (1935) also synonymized Tetrix cuspidata Han- cock, 1907 with L. contractus, but without giving detailed informa- tion.

In contrast to L. tricristatus, the prozonal carinae are not curved to the middle and not keeled. The margins of the fore legs 17] are slightly undulated. Giinther (1935) synonymized Xistra tricris- tata var. sumatrana with Paratettix contractus without giving details. According to Giinther (1939), the specimens of L. sumatrana have in lateral view only slightly visible elevated lateral carinae above the eyes and wavy median carina in front of and behind the shoulders. In the specimens of L. contractus from Borneo, these undulations are weaker. Otte (1997) gave the subspecies a specific status based on occurrence on different islands (as in L. tricristatus mentioned above). All these features are within the range of variation of the species and do not represent diagnostic traits. I did not find dif- ferences when comparing the types and, therefore, L. sumatrana (Bolivar, 1898) (original combination Xistra tricristata sumatrana) is regarded as conspecific with L. contractus.

JOURNAL OF ORTHOPTERA RESEARCH 2019, 28(2) 172 Differential diagnosis.—L. contractus has more or less parallel pro- zonal carinae, slightly bent backwards. The distance between the upper margin of the superior ocelli and frontal margin of the fasti- gium is significantly larger than a diameter of an ocellus in frontal view. The species is similar to L. palawanicus. This species can be easily separated by the tip of fastigium and frontal costa, which are distinctly protuberant in front of the eyes, and the fastigial horns, which are clearly visible above the eyes.

Distribution.—The species inhabits the Southeast Asian mainland (Gunther 1939), Singapore (Hancock 1909), islands of South- east Asia - Sumatra (and adjacent Nias, Mentawai, and Enggano), Java, Borneo, Sulawesi (Giinther 1939), and finally the Solomon Islands. The species has not been found hitherto in New Guinea. Hancock (1907a), however, refers to New Guinea under Xistra tric- ristata, and Ginther (1935) wrote ” (...) also known to me from SE New Guinea”. I have not been able to detect this species in New Guinea and the Bismarck Archipelago, although it is found to inhabit the Solomon Islands.

Differential diagnosis.—L. sagittatus has, together with L. signatus and L. karwinkeli, pulvilli of the hind tarsi bearing apical teeth. Bifurcation of the frontal costa into facial carinae is close to the transverse carinae of the vertex. In L. signatus, the median carina is bent to the tip of the pronotum while in L. sagittatus and L. karwin- keli the median carina rises again in the prozona. In contrast to L. 173 karwinkeli, the median carina of L. sagittatus is flat or weakly wavy. In frontal view, there is a right angle between lateral and transverse carina in L. karwinkeli, while in L. sagittatus the angle is rounded. Notes.—Ginther (1937) retransferred this species to Euparatet- tix, with the note “although certainly related to Lamellitettigodes”. Gunther wrote in 1939 (translation): “I tend to think that the real affinity [of Lamellitettigodes| at least to Euparatettix sagittatus Bol. exists; but this species represents a true Paratettix or Euparatettix, and is to be left in these genera.” L. sagittatus corresponds much better to the genus characteristics of Lamellitettigodes than those of Euparatettix or Paratettix. The carinae are clearly keeled. The pro- zonal carinae are the same as in L. contractus, and the tip of the fas- tigium is clearly protuberant in lateral view. I have examined the HT of Euparatettix pulvillus and agree with the synonymization by Gunther (1937). I have not examined the type of Tetrix polypictus and was not able to check the synonymization by Gunther (1937). Specimens of L. sagittatus have variable size and coloration. Specimens from New Guinea have in frontal view less flattened fastigium than specimens from other regions. However, they be- long to L. sagittatus because all other characteristics are the same.

JOURNAL OF ORTHOPTERA RESEARCH 2019, 28(2) 176 Differential diagnosis.—L. cultratus is unique in having highly la- mellate and arcuate median carina above the shoulders. This char- acter is already visible in nymphal stages. Additional unique char- acters are the short and strongly converging prozonal carinae and short antennae (1.3 times longer than fore femur). Measurements.—(in mm) Pronotum length HT 12.09; pronotum lobe width 2.90; pronotum height HT 2.15; vertex width HT 0.54; eye width HT 0.47; tegmen length HT 1.50; hind wing length HT 11.18; postfemur length HT 4.70; postfemur width HT 1.45. Distribution.—The species inhabits New Guinea, Biak, and the Bis- marck Archipelago — New Britain and New Ireland. Lamellitettigodes palawanicus Gtinther, 1939, stat. nov.

Differential diagnosis.—L. palawanicus has almost parallel prozonal carinae that are slightly bent backwards. The distance between up- per margin of superior ocelli and frontal margin of the fastigium, in frontal view, is significantly larger than the diameter of ocellus. The species is similar to L. contractus. L. palawanicus can be sepa- rated from the similar species by the tip of fastigium and frontal costa that are distinctly protuberant in front of the eyes and by fastigial horns that are clearly visible above the eyes.

Sedlacek, BPBM. Diagnosis.—The species is easily recognizable by the raised median carina with broad depression between the shoulders. This depres- sion clearly distinguishes it from L. cultratus. It is also slightly raised in Chinese L. karwinkeli but does not reach the same height and is not lamellated. As a further feature, the fastigium tip is only slightly visible in front of the eyes. Description.—Body of moderate size and slender. Head and prono- tum smooth. Head and eye in lateral view weakly elevated above the pronotal discus. Dorsal margin of antennal groove slightly above the ventral margin of eye. Eyes small and in lateral view blunt and indistinctly conoidal. Antenna filiform, 14-segmented in male (including scapus and pedicel), while 15-segmented in fe- male, 1.5-2.0 times longer than fore femur. Fastigium of vertex in dorsal view slightly wider than one eye. Fastigium in frontal view between the eyes slightly depressed. Fastigium in dorsal view with well-developed medial and lateral carinae and fossulae. Lateral ca- rina clearly elevated, but in lateral view as high as the dorsal mar- gin of eyes, short, not converging towards the front, bending over at nearly right angles to the medial carina. Transverse carina in dorsal view straight. Frontal costa and facial carina in lateral view minimally visible in front of eye. Tip of fastigium and frontal costa in lateral view slightly, but still clearly, protuberant. Bifurcation of frontal costa into facial carinae between dorsal margin of lateral ocelli and transverse carina, close to transverse carina by less than one diameter of ocellus. Facial carinae in lateral view clearly con- cave in front of eye and slightly convex in front of antenna. Last segments of maxillary palp not widened. Anterior margin of the pronotum truncated. Pronotum slightly widened between shoul- ders. Clearly keeled prozonal carinae converging backwards. Me- dian carina distinctly lamellate from anterior margin of the prono- tum to the end of tegmen, with a broad depression between shoul- ders. Interhumeral carinae absent. Internal lateral carinae weak. Pronotum behind shoulders weakly depressed on both sides of median carina, with large black spots like a broad black band (posthumeral). Lateral lobes broadly rounded, more or less close to body. Tegmen almost as long as the fore femur, rather broad, at the end broadly rounded. Macropterous and macropronotal. Alae clearly exceed the pronotum apex. Fore and middle femora short and widened, with wavy margins. Hind femora with very small an- tegenicular and especially genicular teeth and with some sharply tuberculated raised lobes on the middle outer surface. Posterior tibia distally not or weakly widened, with a few small spines on upper edges. First segment of the hind tarsus not longer than third segment. Pulvilli acute.

Pictures of HT and PT are available in higher resolution in OSF (Cigliano et al. 2019). Distribution.—The species is only known from lowlands in the South of New Guinea (surroundings of Fly River and Lakekamu River). Etymology.—The species is named after the island of New Guinea (Nova Guinea) where it is an endemic species of the genus Lamel- litettigodes. The specific epitheton is made of two words, adjective and noun of the first (A) Latin declension, both in Genitive case (Novae Guineae = novaeguineae).

Lamellitettigodes novaeguineae, 2 HT, W. Lamellitettigodes novaeguineae, 3 PT 9/12; X. Lamellitettigodes karwinkeli, 2 HT. Scale bars: 1 mm. Diagnosis.—L. karwinkeli, together with L. sagittatus and L. signatus species, has pulvilli with apical teeth. Together with L. sagittatus it is a species with long and slender antennae (more than 2 times longer than fore femur. It differs from L. sagittatus by the higher pronotum with a broad depression between the shoulders and morphology of fastigium; in frontal view the ventral margin of transverse carina form a right angle with the lateral carina in L. karwinkeli, while it is rounded in L. sagittatus. Description.—Body long and slender. Head and pronotum smooth. Head and eye in lateral view clearly elevated above pronotal discus. Dorsal margin of antennal groove between eyes, slightly above ven- tral margin of eye. Eyes small and in lateral view blunt and indis- tinctly conoidal. Antenna (4.5 mm) filiform with long and slender segments, 15-segmented in female (including scapus and pedicel), 2.4 times longer than fore femur. Fastigium of vertex in dorsal view smaller than width of one eye. Fastigium in frontal view between the eyes depressed. Ventral margin of transverse carina forming with lateral carina square (right angle). Fastigium in dorsal view with well-developed medial and lateral carinae and fossulae. Lat- eral carina clearly elevated, but in lateral view as high as the dorsal margin of eye, short and not converging towards front, bending over at right angles to the medial carina. Transverse carina in dorsal view slightly convex. Frontal costa and facial carina in lateral view clearly visible in front of eye. Tip of fastigium and frontal costa in lateral view distinctly protuberant. Bifurcation of frontal costa into facial carinae close to transverse carina. Facial carinae in lateral view clearly concave in front of eye and slightly convex in front of anten- na. Last segments of maxillary palp not widened. Anterior margin of pronotum truncated. Pronotum expanded between shoulders. Clearly keeled prozonal carinae slightly converging backwards. Me- dian carina from the anterior margin of the pronotum to the level of the end of tegmen distinctly keeled, with two flattened elevations before and behind shoulders. Interhumeral carinae absent. Internal lateral carinae weak. Pronotum behind shoulders weakly depressed on both sides of median carina with black spots (posthumeral spots) forming broad black band. Lateral lobes broadly rounded, more or less close to body. Tegmen slightly shorter than fore femo- ra, slender, at the end broadly rounded. Macropterous and macro- pronotal. Alae clearly exceed the pronotum apex. Fore and middle femora slender, with slightly undulated margins. Hind femora with very small antegenicular and especially genicular teeth, with some JOURNAL OF ORTHOPTERA RESEARCH 2019, 28(2) J. TUMBRINCK sharply tuberculate raised lobes on the middle outer surface. Pos- terior tibia distally not or weakly widened, with a few small spines on upper edges. First segment of the hind tarsus not longer than the third segment of tarsus. Pulvilli distinctly acute with apical teeth. Measurements.—(in mm) HT: Pronotum length 15.05; pronotum lobe width 3.50; pronotum height 2.15; vertex width 0.47; eye width 0.56; tegmen length 1.65; hind wing length 12.61; postfe- mur length 6.11; postfemur width 1.43. Pictures of HT are available in higher resolution in OSF (Cigli- ano et al. 2019). Distribution.—The species is only known from the type locality near Xishuangbanna (Yunnan, PR China). Note: I cannot find any other species of Lamellitettigodes from PR China. There are likely to be further species from PR China that should be assigned to Lamellitettigodes, but since there are only drawings and only a few photographs, such work remains for future revisions. Etymology.—This species is dedicated to Fabian Karwinkel, a great ornithologist and a committed young conservationist from North- rhine-Westphalia. The specific epitheton is second (US) declen- sion Genitive case of the Fabian’s Latinized version of the surname (Karwinkelus = karwinkeli).

The HT is a typical E. personatus (elevated head, short prozona, hind tibia with a bright light ring). Therefore, I synonymize Probolo- tettix kevani with E. personatus. The description and the drawing of the PT in Blackith and Blackith (1987) refer to a typical Lamellitett- igodes sagittatus and I was able to examine three PTs in BMNH and one paratype in LEMQ: there is no doubt that they are L. sagittatus and do not belong to a new species or to Euparatettix personatus. Scelimena Serville, 1838 Scelimena novaeguineae (Bolivar, 1898) Notes.—I published a wrong specimen as LT (Tumbrinck 2018). The male from IRSNB is a PLT. The correct LT is the following spec- imen: 4, Indonesia, New Guinea, Haveri [9° 22'S, 147°32'E], leg. Loria, vii-xi.1893. It is one specimen of a series of 43 specimens from Haveri. The other 42 are PLT. 179 Acknowledgements My special thanks go to all institutions for graciously lending me specimens from their collections and for the patience they have shown for my research. I especially thank the Zoologische Forschungsmuseum Alexander Koenig in Bonn and their staff for their support and assistance.
