Anthidium (Proanthidium) trochantericum Morawitz, 1893

Anthidium trochantericum Morawitz, 1893: 41 , ♂; Dalla Torre, 1896: 473.

Proanthidium trochantericum Morawitz 1893 : Mavromoustakis, 1939a: 97.

Anthidium luteiventre Friese, 1917: 57 , ♂; Rasmussen & Ascher, 2008: 67.

Anthidium (Proanthidium) trochantericum Morawitz, 1893 : Zanden, 1995: 433.

Diagnosis: The male of this species can be distinguished from other species of subgenus Proanthidium by the distinct but not long spine ventrally on the hind trochanter. It is intermediate between the other two Chinese species that are in the subgenus; in A. kashgarense it is absent, while in A. quingtaoi it is elongate.

Material examined: No specimens examined.

Type locality: Turkestan: Kumar (not located, possibly Komar?) ( trochantericum ), China: Inner Mongolia: Liang (as Liang ( Mongolei) ( luteiventre ).

Distribution: China (Inner Mongolia); Kyrgyzstan, Kazakhstan.

Floral association: unknown.

Remarks: The species is treated as a synonym of Anthidium oblongatum ( Illiger, 1806) by Warncke (1980) and Banaszak & Romasenko (1998), but Mavromoustakis (1939a) and Zanden (1995) treated it as a seperate species. Friese (1917) recorded the holotype of A. luteiventre collecting from “Liang ( Mongolei)”. The length of the flagel- lomeres can apparently be used to distinguish the two species.
