R. concameratus BALkENohL & Schmidt, 2015

– Elytron long-oval, with one dorsal setigerous puncture; pronotum with subcircular outline ( Fig. 1 ). Distribution: western slope of Singalila mountain range, East Nepal ........................................... R. subcirculatus sp. nov.

5 Elytron with three umbilical setigerous punctures; genae developed inconspicuously; clypeus very feebly margined. Distribution: southern slopes of central Annapurna Mts. (Machapuchare and southwestern Lamjung Himal), western Central Nepal ..................... R. jaegeri BALkENohL & Schmidt, 1997

– Elytron with two umbilical setigerous punctures; genae well developed; clypeus feebly but distinctly margined........................................................ 6

6 Elytron with one dorsal (anterior) setigerous puncture; lateral channel of pronotum deep and moderately broad ( Fig. 3 ). Distribution: Lapchi Kang mountain range, central Nepal ............................ R. loebli BALkENohL, 1994

– Elyton with two dorsal setigerous punctures; lateral channel of pronotum shallow and narrow ..................................................................................... 7

7 Outline of pronotum appearing subcircular, globose, lateral channel very small at middle, not completely visible from above due to globosity of pronotum, surface with microscopic irregular reticulation; genae enclosing eyes posteriorly by a quarter; disc of head with irregular microscopic pattern (magnification 160 times); elytra conspicuously elliptical ( Fig. 4 ), basal setigerous puncture situated in extended prolongation of first stria, minute striole at base. Distribution: mountains east of Arun Valley, East Nepal (Milke Danda, Jaljale Himal) ........... R. ellipsoideus BALkENohL, 1995

– Outline of pronotum long-convex or regularly convex, lateral channel distinct, visible throughout from above, surface smooth; genae enclosing eyes posteriorly by a tenth; disc of head appearing smooth (magnification 160 times); elytra long-oval or egg-shaped, basal setigerous puncture situated in extended prolongation of second interval, no trace of striole at base ............................................................................................................ 8

8 Pronotum long-globose, longer narrowed towards base, reflexed lateral margin ending at posterior setigerous puncture; elytra long-oval with maximum width slightly anterior to middle, striae distinct up to apex, intervals flattened; eyes less convex. Distribution: south eastern slope of Annapurna Mts. (south eastern Lamjung Himal), western Central Nepal ........................ ........................................... R. variobasalis BALkENohL & Schmidt, 2015

– Pronotum more regularly-globose, narrowed with slightly rounded elongation towards base, reflexed lateral margin extended distinctly over posterior setigerous puncture; eyes regularly convex............................................ 9

9 Reflexed lateral margin of pronotum extended over posterior setigerous puncture by three times the diameter of puncture; elytra egg-shaped, more markedly narrowed towards base than in the following species, striae disappearing apically, intervals slightly convex. Distribution: south western slopes of Manaslu Himal, western Central Nepal .......................................... .............................................. R. similitudis BALkENohL & Schmidt, 2015

– Reflexed lateral margin of pronotum extended over posterior setigerous puncture by more than a third of distance from posterior puncture to base; elytra long-oval, striae all distinct up to apex, intervals flat (with exception of first interval). Distribution: Lamjura Danda mountain range of Solu Khumbu massif, eastern Central Nepal ......................................................... .......................................... R. duospinosus BALkENohL & Schmidt, 2015
