Type locality: Nepal, Sindhupalchowk District, Yangri Mountains, 4350 m alt.

Diagnosis of males: Length 2.63-2.76 mm. Antennal clubs lacking modification. Metaventral processes long, apically broadened. Profemora with small ventral projection, protibiae with distinct projection at apex; mesotrochanters with slender ventral spine, mesotibiae with small projection at apex; metafemora broadly thickened ventrally. Median lobe of aedeagus narrowed apically; parameres slender and elongate.

Description: Male (Fig. 1A). Body reddish brown, BL 2.63-2.76 mm. Head slightly longer than wide, HL 0.53-0.55 mm, HW 0.52-0.53 mm; each eye composed of about 26 facets; ocular canthus weak. Antennomeres (Fig. 2A) 9-11 forming distinct enlarged club, lacking modification. Pronotum (Fig. 2B) slightly longer than wide, PL 0.59-0.61 mm, PW 0.56-0.59 mm, rounded at anterolateral margins, strongly constricted at apical third. Elytra wider than long, EL 0.73-0.79 mm, EW 1.11-1.16 mm. Metaventral processes (Fig. 2C) long, apically broadened. Profemora (Fig. 2D) with small ventral projection, protibiae (Fig. 2E) with distinct projection at apex; mesotrochanters (Fig. 2F) with slender ventral spine; mesotibiae (Fig. 2G) with small projection at apex; metafemora (Fig. 2H) broadly thickened ventrally. Abdomen broad at base and narrowing apically, AL 0.78-0.81 mm, AW 1.16- 1.17 mm. Sternite IX semi-membranous, shape as in Fig. 2I. Length of aedeagus (Figs 2 J-L) 0.61 mm; median lobe asymmetric; apically narrowed, parameres elongate; endophallus composed of one long and one short sclerites.

Female. Each eye composed of about 23 facets; antennae simple. Measurements: BL 2.78-2.80 mm, HL 0.55- 0.56 mm, HW 0.53-0.56 mm, PL 0.58-0.64 mm, PW 0.59-0.61 mm, EL 0.74-0.76 mm, EW 1.23-1.32 mm, AL 0.87-0.88 mm, AW 1.23-1.32 mm.

Distribution: Nepal, Bagmati.

Comparative notes: This species can be readily separated from all other congeners from Nepal based on the simple antennal clubs, the apically broadened metaventral processes, and the unique form of the aedeagus.

Etymology: The specific epithet ‘ ampliatus ’ means ‘widened, extended, enlarged’, referring to the strongly expanded male femora of the new species.
