Dasypoda (Megadasypoda) vulpecula Lebedev, 1929 View in CoL
This species was described by Lebedev based on material including about 30 specimens of males and females collected from Kazakhstan: [coast of river] Usek near Jarkent [44.186, 79.974], former prov. Semirechye [or Jetysu; now Panfilov District of Almaty Region] ( Lebedev 1929: 269–271). This type material was deposited in Kiev (Institute of Zoology, Academy of Sciences of Ukraine), but probably was lost during World War II. Besides this first description, D. vulpecula has been listed by Popov (1957), who referred to a single female collected from Shohimardon [39.984, 71.799]—an exclave of Uzbekistan, surrounded by Kyrgyzstan, in a valley in the Alai mountains, but this specimen was probably also lost. Finally, the species has been mentioned without any reference in the Red Book of Kyrgyz Republic ( Davletkeldiev 2006: p. 293) as a species that required special attention for its conservation.
We found two females and one male of D. vulpecula among undetermined material stored in different collections that allowed us to make a redescription of both sexes and to clarify the subgeneric assignment of the species. One of the females was collected relatively close to the locus typicus (300 km from the same Almaty region) but this specimen was significantly damaged by a Dermestes larva. The second female was collected 230 km from the locus typicus, but this point is located in another country (in Kyrgyzstan). The male was also collected from Kazakhstan, however at a distance of about 2,000 km from the type locality. It shows a very clear, unique diagnostic feature, namely a large beak-shaped protrusion on the distal part of hind tibia ( Figs 88, 91 View FIGURE 80–91 ). This trait was shown on the figure along with the original description of this species ( Lebedev, 1929: 270, Fig. 1 View FIGURE 1–12 ) that excludes possible misidentification, in contrast with original description of females, which do not have such unique features. Moreover, Dasypoda vulpecula shows the characteristic structure of the genitalia of the subgenus Megadasypoda . According to the structure of S6–S8 and genitals, D. vulpecula is most similar to D. (Megadasypoda) friesana Schletterer, 1890 but this species does not show the particular structure on the hind tibia.

All terga with yellow-ginger long hair erected or semi-erected on T1–T2 and more appressed on other ones except on their sides. Each hair rising from oblique backward-directed puncture. Distance between two punctures about 2–4 times as long as diameter of punctures. Marginal parts of each tergum semi-translucent, not punctured, hairless and lighter than apical parts. Sterna hairy, with short yellow-ginger hair only on sides of basal part and longer at margin, rest of sterna with very short sparse setae. Central apical part of S6 widely concave ( Fig. 92 View FIGURE 92–98 ). Distal part of S7 with long latero-apical processes ( Figs 93, 96 View FIGURE 92–98 ).
