Anthidium (Proanthidium) kashgarense ( Cockerell, 1911) : Kasparek, 2017: 17.

Diagnosis: This species is very similar to Anthidium (Proanthidium) oblongatum ( Latreille, 1809) and can be distinguished from A. (P.) oblongatum by the following combination of characters: female F1 about 2.0X as long as broad ( Fig. 37d ), male F1 about 1.8X as long as broad ( Fig. 38c ), anterior surface of the male F1–F2 and the female F2–F4 reddish-brown, propodeal triangle with dense punctures, apical process of male S8 sub-triangular and rounded apically ( Fig. 38h ).

Description: Male (new). BL = 10.8–11.5 mm ( Fig. 38a ); head broader than long, HW: HL = 82: 68 ( Fig. 38b ); gena slightly broader than eye, GW: EW = 20: 18. Clypeus nearly as broad as long, with longitudinal smooth area medially, apical margin of clypeus smooth, straight medially ( Fig. 38b ); mandible with three teeth, apical one sharp, longest, third one broad, blunt; F1 about 1.8 times as long as broad, shorter than F2 + F3 together ( Fig. 38c ); omaular carina absent; pronotal lobe lamellate anteriorly; scutellum with small triangulate tooth posterolaterally, greatly overhanging metanotum and propodeum ( Fig. 38d ); propodeum without fovea behind spiracle; fore wing with two submarginal cells, cells nearly equal in length, second recurrent vein meets distal to second submarginal crossvein; arolia absent; apical margin of S6 slightly emarginated, without lateral lobe, and median lobe slight projected ( Fig. 38g ); apical process of S8 sub-triangular, rounded apically ( Fig. 38h ); T6 with midapical projection on distal margin, lateral spine distinct long and sharp ( Fig. 38f ); T7 without median spine, lateral lobe with outer margin broadly convex, inner margin nearly straight ( Fig. 38f ); genitalia shown in Fig. 38i (in dorsal view), gonostylus broad and rounded apically ( Fig. 38i ); hind trochanteric spine short and blunt ( Fig. 38j ). T1–T6 with broadly interrupted yellowish-brown bands, becoming progressively closer on apical, forming distinctive black, broad V-shaped area across terga ( Fig. 38e ). Integument black, except reddish-brown on anterior surface of F1 and F2 ( Fig. 38c ), apical margin of scutellum (part, Fig. 38 d-1); dark blackish brown on anterior surface of F3–F11 ( Fig. 38c ); yellow on clypeus, lower part of paraocular area and outer surface of mandible except teeth ( Fig. 38b ); yellowish-brown on one large marking on vertex near apex of eye, tegula, ventral parts of middle and hind coxae, femora, tarsi, basitarsi, and lateral part of T7 ( Fig. 38f ); blackish-brown on teeth ( Fig. 38b ), fore coxa, and trochanters ( Fig. 38j ); dark brownish on sterna ( Fig. 38g ). Fore wing hyaline, veins brownish and stigma dark brownish. Lower part of face, gena, and lower part of mesepisternum covered with long and dense white pubescence ( Fig. 38b ); vertex, scutum, and scutellum covered long and sparse pale yellowish-white pubescence ( Fig. 38c , Fig. 38d ); lateral side of metasomal terga covered with long and dense yellowish pubescence; apical margin of S4 covered with dense yellowishbrown pubescence, not forming brush, apical lateral margin of S5 covered long yellowish-brown pubescence ( Fig. 38g ); outer surface of basitarsi covered with long and sparse yellowish-white hair, inner surface of basitarsi covered with short and dense golden hair; coxae, trochanters, femora and tibiae covered with long sparse pale yellowishwhite hair, and outer apical margin of hind tibiae covered with short and dense white pubescence.

Type locality. China: Xinjiang Uygur: Kashgar .

Distribution: China (Hebei, Inner Mongolia, Xinjiang).

Floral association: Hedysarum mongolicum (Fagaceae) .

Remarks: The male is described for the first time here. Wu (2006) misidentified some female specimens as A. (P.) oblongatum ( Latreille, 1809) , but the female F1 is about 2.0X as long as broad ( Fig. 37d ), the male F1 is about 1.8X as long as broad ( Fig. 38c ), the anterior surface of the male F1–F2 and the female F2–F4 are reddish-brown, propodeal triangle with dense punctures, apical process of male S8 is sub-triangular and rounded apically ( Fig. 38h ), and these characters separate this species from A. (P.) oblongatum ( Illiger, 1806) (F1 of female and male about 1.4X as long as broad, the color of flegellomere is black, propodeal triangle of female shiny, nearly smooth, apical process of male S8 subquadrate, truncate apically). Consequently, A. (P.) oblongatum ( Illiger, 1806) does not currently occur in China, although Ebmer (2010) thought it occurs in Xinjiang of China.
