Rugilus (Rugilus) quadridentatus (COIFFAIT 1975)

( Fig. 7 )

Material examined: Nepal: 5 exs., SW-Dhaulagiri, Rahughat Khola valley, SW Lete Pass, above Dwari, 28°34'N, 83°32'E, 2500 m, 12.V.2002, leg. Jäger (SNSD, cAss).

Comment: Since this species was previously known only from the environs of Pokhara, it was assumed to be endemic to the Annapurna range ( ASSING 2012a). However, the above record and the discovery of two similar micropterous species in the Annapurna range suggest that R. quadridentatus is actually endemic to the Dhaulagiri region. The distinctive male sternite VII is illustrated in Fig. 7 .
