Rugilus (Rugilus) schuelkei ASSING, 2012

M a t e r i a l e x a m i n e d: China:Y u n n a n: 3♂♂, 20♀♀, Haba Shan, 27°22'N, 100°06'E, 3270 m, sifted, 29.VI.2012, leg. Grebennikov; 1♀, Haba Shan, 27°21'N, 100°06'E, 4070 m, sifted, 28.VI.2012, leg. Grebennikov; 1♀, Haba Shan, 27°22'N, 100°07'E, 3360 m, sifted, 29.VI.2012, leg. Grebennikov (material in CAS, cSme, cAss) .

C o m m e n t: The known distribution is confined to several localities in the environs of Zhongdian (ASSING 2012a, 2012b, 2015). This species, too, is subject to a sexual wing-dimorphism (males macropterous; females brachypterous) and a biased sex ratio. The ratio in the material studied up to today is 0.25 (13 males: 53 females).

Rugilus (Rugilus) meilixuensis ASSING, 2012 M a t e r i a l e x a m i n e d: China: Y u n n a n: 5♂♂ [1 macropterous], 20♀♀, 15 km W

Deqin, Mingyong, 28°27'N, 98°45', 3290 m, sifted, 29.VI.2012, leg. Grebennikov; 5♂♂ [2 macropterous], 17♀♀, 15 km W Deqin, Mingyong, 28°27'N, 98°45', 3260 m, sifted, 29.VI.2012, leg. Grebennikov (material in CAS, cSme, cAss) .

C o m m e n t: All known records of R. meilixuensis are from the Meili Xue Shan (ASSING 2012a, 2012a, 2013). The above material confirms an earlier hypothesis (ASSING 2012a) that the males are indeed wing-dimorphic. Thus, this species is subject to a sexual wing-trimorphism (males macropterous or brachypterous with the elytra not dilated posteriorly; females brachypterous with the elytra shorter than in brachypterous males and dilated posteriorly). The sex ratio in the material studied up to today is 0.25 (11 males: 44 females); four males are macropterous, the remainder brachypterous.
