Eodorcadion (Ornatodorcadion) argaloides Breuning, 1947

Literature data. Dornogovi: 30 km SSE of Tenger-Nuur Lake [оЗ.Тэнгэр-Нур] [ca. 42.419, 108.682], in Lasiagrostis and Stipa grass, 04.08.1971, 32 exx. ( Namhaidorzh 1976a: as Eodorcadion oryx ); [the same label data], 2 ♂♂, D. Magmarsuren leg. (or B. Namhaidorzh leg.), both identified as “ Eodorcadion oryx ” by B. Namhaidorzh (ZIN) ( Danilevsky 2007); Mt. Nomt-Uul, 30 km SSE Shokhoi-Nuur Lake [ca. 42.505, 109.237], 4.08.1971, 2 ♂♂, 2 ♀♀, G. Medvedev leg. (ZIN, JV, MD), 1 ♂, Kozlov leg. (MD) (ibid).

Remarks. Eodorcadion argaloides is distributed in Mongolia and northern China (Inner Mongolia) ( Danilevsky 2020). It was described based on a single female specimen, whose label data does not allow to determine the exact type locality. Additional material revised by Danilevsky (2007) made it possible to localise four sites of this species in the southern part of Dornogovi aimag. However, it is worth noting that the author has studied only the specimens from the two southernmost localities (30 km SSE of Tenger-Nuur Lake; Mt. Nomt-Uul, 30 km SSE Shokhoi-Nuur Lake).

We have investigated the area east of Shokhoi-Nuur Lake (previously also visited by B. Namhaidorzh), however, we exclusively found there (in two separate sites) individuals that clearly represent Eodorcadion gorbunovi (Danilevsky, 2004) , not E. argaloides . They do not differ from those collected by us in big numbers in the type locality of E. gorbunovi and its vicinity. This clearly evidences that the two localities given by Danilevsky (2007) (25 km E of Shokhoi-Nuur Lake; Mt. Khutag-Uul), from which the specimens have not been examined, should refer to E. gorbunovi rather than E. argaloides and, consequently, they are presented as such in this paper. Therefore, in Mongolia, the real known range of the latter species is apparently limited to a narrow belt along the border zone ( Fig. 4 ). Another issue is the placement of particular localities in the Danilevsky’s (2007) map (including these two that should refer to E. gorbunovi ). They need to be verified since according to local entomologists from Mongolian Academy of Sciences, the Mountain Nomt-Uul (30 km SSE Shokhoi-Nuur Lake) is located more to the south.
