Abstract

A new species, Zemelucha rea sp. n., of the ichneumon wasp subfamily Cremastinae is described from
Malta. Since the last published keys to the Western Palaearctic species of Temelucha are outdated and lack
several species, an updated and revised identification key is provided for the 47 known Temelucha species

of the region.

Introduction

Temelucha Forster, 1869 is a moderately species-rich genus of the ichneumon wasp sub-
family Cremastinae. The definition of the genus was summarized by Townes (1971).
According to Yu et al. (2012), 235 valid species belong to this genus, with worldwide
distribution, and 46 species have been known from the Western Palaearctic region. The

early keys provided for the Western Palaearctic species of Temelucha (i.e. in combina-
tion with Cremastus Gravenhorst, 1829 at that time) are seriously outdated by now and
cover only a very limited set of species (e.g. Szépligeti 1905, Schmiedeknecht 1910).
The only comprehensive taxonomic revision of the European species was published by
Sedivy (1971). In his work he not only provided a useful key for the 23 European Te-
melucha species known at that time but also gave detailed descriptions for all the species.
As several, previously described species were published with insufhcient morphological
descriptions, Sedivy’s (1971) work is still a base-line for the European species.

Since Sedivy’s (1971) revision, several new species have been described from the
Western Palaearctic region, mainly from the Balkan Peninsula and the Mediterranean
area (Aubert 1977, 1981, Narolsky 1987, Kolarov 1989, Sedivy and Schwarz 1993,
Kolarov 1995, 1996, Kolarov and Beyarslan 1999, Narolsky 2004). Kolarov (1997)
provided a new key for 36 species of the region with a valuable zoogeographical discus-
sion. His key includes many but not all species that have been described since Sedivy
(1971) and it was a good attempt to simplify the distinguishing characters; however,
some mistakes could be revealed by comparing the distinguishing characters of some
species in that key with the original descriptions and type specimens (e.g. a species
known only from males could only be keyed out by choosing between ovipositor char-
acteristics, or a species with a yellow scutellum was keyed in the section of species with
a black scutellum, etc.). Additionally, some species described long ago, such as Teme-
lucha corsicator Aubert, 1961, T. picticollis (Hellén, 1949), and T. minuta (Morley,
1912) were included in neither previous key.

Recently, by finding a new Temelucha species from Malta, I realized the necessity
of an updated identification key which covers all the species of the region and corrects
the errors of the previous keys. In this paper, along with the description of a new spe-
cies, an identification key is provided for the 47 currently known Western Palaearctic
Temelucha species (including the one described here).

Methods

Ichneumonidae taxonomy and nomenclature follow Yu and Horstmann (1997) and
Yu et al. (2012). The morphological terminology follows Gauld (1991), and Gauld
et al. (1997). The updated and revised key is based on previous keys (Sedivy 1971,
Kolarov 1997), original descriptions and descriptions given by Sedivy (1971), Narol-
sky (1990), Kolarov and Beyarslan (1999), Kolarov and Yurtcan (2009), and Rousse
et al. (2011). The key was tested on the material of the Hungarian Natural History
Museum (HNHM), Budapest. The author examined the types of species described by
Szépligeti (deposited in HNHM), and of 7 picticollis (Hellén) (borrowed from the
Finnish Natural History Museum, Helsinki). Distribution notes are not given in the
key; it would just repeat Kolarov’s (1997) work, and are well summarized in Yu et al.
(2012). The specimens were examined using Nikon SMZ645 and Olympus SZX9
stereoscopic microscopes. Photos were taken by T. Németh (HNHM Coleoptera Col-

lection) with Nikon D5200 and Nikon AF Micro Nikkor 60mm lens and Mitutoyo
M Plan Apo 5X microscope lens. Exposures were stacked in Zerene Stacker, post image

work was done with Photoshop CS5.

Temelucha rea sp. n.

http://zoobank.org/349622C9-A95A-426A-9B02-27207B7 13487

Material examined. Holotype: female, Malta, Mellieha, Il-Prajjet, 14.viii.2014, leg.
M. Zammit. Paratype: female, same locality, collecting date, and collector. The holo-
type and the paratype are deposited in the HNHM Hymenoptera Collection (HNHM
Id. No. 23011, 23012, respectively).

Diagnosis. The new species belongs to the morphological group of Temelucha spe-
cies with the following characters in combination: mainly yellow head and thorax, at
least the basal part of the hind coxa dark, the second discal cell more than 1.5 x as long
as the first sub-discal cell, and the second recurrent vein (27m-cu) postfurcal. Within
this group it most resembles T° decorata (Gravenhorst, 1829) due to its colour pattern;
however, it is significantly smaller than 7! decorata. Another such small species within
this group is T° picticollis (Hellén, 1949); however, T° picticollis differs from the newly
described species by its black propodeum, the absence of notauli, and colour pattern.

Description. Female (holotype) (Figs 1-4). Body length 4.7 mm, fore wing length
2.7 mm, ovipositor sheath 2.0 mm.

Head. Antenna with 26 flagellomeres. First flagellomere 3.3 x as long as wide.
Gena short, strongly constricted behind eyes. Occipital carina dorsomedially incom-
plete. Occiput smooth and shiny. Vertex, frons, gena and malar space finely coria-
ceous. Middle of face punctate, punctures separated from each other by usually less
than a puncture diameter. Clypeus with fewer punctures, convex in profile, and with
curved apical margin. Inner eye orbits parallel. Ocellus diameter slightly smaller than
distance between lateral ocellus and eye. Malar space about 0.75 x as long as basal
width of mandible. Mandibular teeth of equal length.

Mesosoma. Mesosoma densely punctate; distance between punctures on mes-
onotum and mesopleuron generally smaller than puncture diameter. Pronotum less
densely punctate and with fine wrinkles. Epomia distinct. Notaulus distinct, reaching
middle of mecoscutum. Scutellum punctate with lateral carinae not reaching its mid-
dle. Sternaulus indistinct. Speculum shiny and almost impunctate. Epicnemial carina
present, reaching above middle of hind edge of pronotum. Posterior transverse carina
of mesosternum complete. Metanotum (including postscutellum) with longitudinal
wrinkles and a few punctures. Metapleuron densely punctate. Legs slender, hind femur
about 5 x as long as wide. Tarsal claws small and thin, only slightly longer than aro-

lium. Propodeum long, only very weakly convex in profile with its apical edge reach-
ing middle of hind coxa. Pleural carina complete, its distance from circular propodeal
spiracle about equal to diameter of spiracle. Spiracle connected to pleural carina by a
raised ridge. Lateromedian and lateral longitudinal carinae and basal transverse carina
complete. Median section of apical transverse carina indistinct. Pleural areas strongly
punctate. Lateral areas with dense punctures and sparse transverse wrinkles. Area ba-
salis very small with almost parallel lateral carinae on its basal half. Area superomedia
and area petiolaris indistinctly separated; both areas narrow, almost parallel-sided and
with dense transverse striation, except basal part of area superomedia, which is almost
triangular-shaped and less striate, rather shiny with a few punctures.

Wings. Wing membrane with dense short hairs. Fore wing with vein cu-a intersti-
tial. Vein 2mm-cu postfurcal with a wide bulla. Distal abscissa of Rs almost completely
straight. Second discal cell about 2 x as long as first sub-discal cell (measured at front
margins). Pterostigma slightly shorter than front margin of marginal cell. Hind wing
with vein cu-a + abscissa of Cul between M and cu-a almost straight, not intercepted.
Distal abscissa of Cu1 spectral.

Metasoma. First metasomal segment slightly longer (about 1.15 x) than second
segment. Ventral margins of first tergite touching each other ventrally. Lateromedian
carinae of first tergite relatively weak. Second tergite with longitudinal striation char-
acteristic of many Cremastinae. Third tergite coriaceous. Following tergites mainly
punctate. Metasoma strongly laterally compressed, especially from third tergite on.
Ovipositor sheath twice as long as hind tibia (or as long as fore wing from base to mid-
dle of marginal cell). Ovipositor straight, laterally compressed with distinct subapical
notch. Apex smooth and straight, with subapical part somewhat widened in profile.

lowish edges and hind corner. Mesoscutum yellow with an anteromedian black patch
and two posterolateral brownish patches. Hind edge of mesoscutum and scutellar
groove black. Scutellum entirely yellow. Mesopleuron mainly reddish and yellowish
with black patches on ventral parts. Metanotum dark brown, its center somewhat
lighter reddish brown. Metapleuron reddish and yellowish, its anterior ventral corner
black. Propodeum almost entirely pale reddish, only basally black, medially reaching
only basal part of area superomedia.

Fore and mid legs: coxae yellow with brownish patches basally; trochanters and
trochantelli yellow; femora, tibiae and tarsomeres pale reddish except brown apical
tarsomeres. Hind leg: coxa basally black; trochanter and trochantellus brown with yel-
lowish apical parts; femur brown, basally and apically yellowish brown; tibia yellowish
brown in middle, basally and apically brown; tarsomeres brown with yellowish brown
base of first tarsomere; apical tarsomere dark brown.

characteristics described above except that it is darker than the holotype. The brownish
patch in the midline of the upper face is larger and black; pronotum more reddish; the
posterolateral dark patches of the mesoscutum are black; mesopleuron with less yel-
lowish and more reddish colouration and almost black around the speculum; metano-
tum almost black; propodeum darker, the basal half black, apical half pale reddish;
hind tibia darker brown in the middle; the first and second tergites are darker, the light
edges of the apical tergites are slightly darker.

Male. Unknown.

Distribution. Currently known only from Malta.

Ecological note. Adult wasps emerged on 14.viii.2014 from flowers of Limbarda
crithmoides (Linnaeus) collected on 8.ix.2014. Several adult moths of Eublemma parva
(Hiibner) (Lepidoptera: Noctuidae) also emerged from the flowers; most probably it
is the host species.

Etymology. Arbitrary combination of letters, feminine gender.
