Journal of Hymenoptera Research 79: 145-162. https://doi.org/10.3897/jhr.79.57276 Abstract Continuing prior studies on Chinese Sphecodes, we here report further records of twelve rarely collected and little known species from mountainous regions of Southern and South-Western China (Xizang, Si- chuan, Yunnan). Forty two species are currently known from China, yet until now only two species were known from Southern and South-Western China. We report six entirely new records for China, including Sphecodes discoverlifei Astafurova & Proshchalykin, 2020, S. fumipennis Smith, 1853, S. montanus Smith, 1879, S. nipponicus Yasumatsu & Hirashima, 1951, S. simlaensis Bliithgen, 1924, and S. turneri Cocker- ell, 1916, and another four are new regional records. Two are new species that we describe and illustrate: Sphecodes holgeri Astafurova & Proshchalykin, sp. nov. (Yunnan), and S. tibeticus Astafurova & Niu, sp. nov. (Xizang). The male of Sphecodes sikkimensis Bliithgen, 1927 is described for the first time. Keywords Anthophila, Apiformes, cleptoparasites, fauna, new species, taxonomy Copyright Yulia V. Astafurova et al.

Astafurova et al. / Journal of Hymenoptera Research 79: 145—162 (2020) Introduction There are currently 328 bee species of the family Halictidae known from China (Niu et al. 2018), but new records and species continue to be added (Niu et al. 2020; Zhang et al. 2020). The genus Sphecodes Latreille, 1804 has been one of the more overlooked taxa part- ly due to the complexity of identifying material. However, in last two years, significant progress has been made towards bettering our knowledge of the Chinese Sphecodes. Through the publication of our first paper dealing with Sphecodes from the Palaearctic part of China (Astafurova et al. 2018), the number of known species of the genus increased from 18 to 34. However, the Sphecodes fauna of the mountainous regions of Southern and South-Western China (Xizang, Sichuan, Yunnan) remains poorly known. For example, only one species of this genus — Sphecodes grahami Cockerell, 1922 — has been described from Sichuan so far, and in total only two species have been previously recorded for this part of country (Astafurova et al. 2018). In the present paper, based on a comprehensive study of specimens held in vari- ous collections, we report twelve new species distributional records, with two species described as new and six species recorded from China for the first time, resulting in a total number of 42 Sphecodes species known from this country (Table 1). In addition, we describe the male of Sphecodes sikkimensis Bliithgen, 1927 for the first time. Cleptoparasitic bees are often rare and research was consequently hindered by the small number of specimens stored in collection and the unusually wide intraspecific morphological variation of the studied taxa. Many species are known only from type series or from a single sex, and a several primary types could not be found or are confirmed to have been lost. Despite these challenges, this contribution represents a significant step towards a better documentation of the species of Sphecodes and their distributional patterns in China, an essential foundation for advancing faunal inves- tigations into the Palaearctic and Oriental regions and the biogeographic division be- tween the two. Materials and methods The results presented in this paper are based on 92 specimens collected in mountain- ous regions of Southern and South-Western China (Xizang, Sichuan, Yunnan) that are currently housed in the Institute of Zoology, Chinese Academy of Sciences, Beijing, China (IZCAS); the Zoological Institute, Russian Academy of Sciences, St. Petersburg, Russia (ZISP); and the private collection of Maximilian Schwarz, Ansfelden, Austria (PCMS).

Astafurova et al. / Journal of Hymenoptera Research 79: 145—162 (2020) The taxonomy and distribution of species follows that of Astafurova et al. (2018, 2020). Diagnosis and descriptive notes for most of the species listed below can be found in Astafurova et al. (2020). Morphological terminology follows that of Engel (2001) and Michener (2007). The ventral surface of some flagellomeres bear a distinc- tive patch of sensilla trichodea A (sensu Argent and Svensson 1982), which we refer to as ‘tyloids’, and they are easily observable under a microscope. Abbreviations F, T, and S are used for flagellomere, metasomal tergum and metasomal sternum, respectively. The density of integumental punctures is described using the following formula: puncture diameter (in um) / ratio of distance between punctures to average puncture diameter, e.g., 15-20 um / 0.5—1.5. Integumental sculpture other than distinctive surface punc- tation is described following Harris (1979): areolate — coarse, contiguous punctures; reticulate — superficially net-like or network of raised lines; rugose — irregular, nonpar- allel, wrinkled raised lines (rugae); rugulose — minutely rugose; strigate — narrow, trans- verse or longitudinal streaks (strigae), variety of parallel lineations; tessellate — regular network of shallow grooves with flat interspaces. Specimens were studied with a Leica M205A stereomicroscope and photographs taken with a combination of stereomicroscope (Olympus SZX10) and digital camera (Olympus OM-D and Canon EOS70D). Final images are stacked composites using Helicon Focus 6. All images were post-processed for contrast and brightness using Adobe Photoshop. New distributional records are noted with an asterisk (*).

The female exhibits variation in the degree of punctation on the mar- ginal zones of T1, ranging from with denser punctures separated by 1—5 puncture di- ameters (typical form) to almost impunctate with a few tiny punctures (1 9, Sichuan, Mujiangping). Specimens from China have fewer hind wing hamuli (9-11 versus 11— 12 in other studied specimens from India and Southeast Asia). Interesting specimens of a black form were collected in montane Yunnan (1 9, 3 6; Zhongdian, Xiagiao- tou, 1800 m). Unlike the typical form with red colourised T1—T4, these individuals have entirely black metasomas. Similar variation in coloration was also studied by us (unpublished data) in other Sphecodes species (S. monilicornis (Kirby, 1802), S. nippon Meyer, 1922, S. intermedius Blithgen, 1923, S. olivieri Lepeletier de Saint-Fargeau, 1825, S. pectoralis Morawitz, 1876, S. pinguiculus Pérez, 1903).

Material examined. — Published records. Cockerell 1922: 12 (Sichuan); 1931: 12 (Shanghai); Astafuro- va et al. 2018: 30 (Shanxi, Shaanxi). Remark. According to Wu (1965) and Wu et al. (1988) this species was recorded from different provinces of China (Jilin, Hebei, Anhui, Jiangsu, Shandong, Shanghai, Zhejiang, Sichuan, Yunnan, Xizang, Guandong). However, re-identification of speci- mens from the IZCAS Collection determined by Prof. Wu as S. grahami as well as the analysis of the descriptive notes given in these works revealed misidentifications. In fact, the specimens from Yunnan (1 9, Lijiang) and Sichuan (1 3S, Barkam; 1 9, Xi- angcheng) belong to S. pieli. These two species are very similar structurally and sculp- turally, but S. grahami differs by lack of a longitudinal carina on vertex (also indicated in Cockerell 1922: 12). In contrast, the longitudinal carina on vertex in S. pieli is clear- ly developed, corresponding to descriptive notes by Wu (1965) and Wu et al. (1988), where pointed on “small process on vertex”. Among determined by Wu specimens we have not found any specimens from Xizang, with records from this province (Wu et al. 1988) instead referring to S. montanus, another species similar to S. grahami with a 150 Yulia V. Astafurova et al. / Journal of Hymenoptera Research 79: 145—162 (2020) vertex carina. So, males of S. grahami recorded by Wu, 1965 and Wu et al. 1988 refer to other species, and the male of S. grahami remains unknown. The female of this spe- cies is difficult to distinguish from the vicarious West-Palaearctic S. ephippius (Linné, 1767) and it is also similar to S. pellucidus var. gibridus Bliithgen, 1924. Clarification of the status of this species and possible synonymy is a task for future study. Distribution. China (Shanxi, Shaanxi, Shanghai, Sichuan).

Propodeal triangle sculpturing varies from coarsely reticulate-rugose (medially forming 2—3 rows close to square or shapeless cells) to with parallel wrinkles and large shining interspaces (forming a row of longitudinal cells). Distribution. “China (Yunnan); India (Meghalaya), Laos. Discussion In total, 42 species of Sphecodes are now recorded from China. For comparison, to demonstrate the high species richness of the Chinese fauna, approximately 120 species are known from the entire Palaearctic and Oriental Regions together. However, the Chinese fauna of the genus (especially from the Oriental part) is poorly studied. Con- seugently, even following our addition of ten new species records, only twelve species are known from Xizang, Sichuan, and Yunnan. To accurately assess Sphecodes distribution patterns in China requires a more in- depth studying of this country’s fauna. Overall, the fauna of south and south-east mountain territories of China is similar to the faunas of Southeast Asia and the Him- alayas. Seven species from the studied provinces (Sphecodes discoverlifei, S. fumipen- nis, S laticeps, S. montanus, S. simlaensis, S. sikkimensis, and S. turneri) are also found in montane Southeast Asia or the Himalayas. Another three species (S. pieli, S. nipponicus and S. grahami) are elements of the eastern Palaearctic and Oriental fauna and pre- dominantly occur in plains or foothills. The high habitat heterogeneity of these areas promises additional new species with further collections and taxonomic investigations.
