Aragara atra (Duda, 1934) , comb. nov.

( Figs 1–4 )

Oscinis atra Duda, 1934: 141–142 (original designation)

Distribution: Indonesia (Sumatra).

Specimens examined: Lectotype ♁ Sumatra, Fort de Kock , 920 m, leg. E. Jacobson ( MfN; http://coll.mfn-berlin. de/u/b8d633) new designation, paralectotypes 2 ♁ 1 ♀ idem ( MfN) new designations.

Comments: Dark stout species (fig. 1A); fore femur slightly enlarged, with eight short spines (fig. 1B); ocellar triangle with one mesal and two lateral longitudinal grooves; frons apex yellow; arista with short pubescence (fig. 2). Male genitalia (figs. 3–4) with anal lobe bearing one pair of anal sclerites; mesolobus drop-shaped; surstylus with small spines apically; postgonite longer than pregonite; epiphallus membranous; basiphallus round apically; and distiphallus long.

Externally, A. atra comb. nov. shares similarities with A. femorata and A. menglaensis and the coloration of the abdominal syntergite 1+2 is doubtful in A. atra . Aragara menglaensis has a relatively similar male terminalia, but the fore femur has 10–11 spines, basal abdominal tergites are mostly yellow, unlike A. atra and A. femorata . On the other hand, the distinction between A. atra comb. nov. and A. femorata seems to be restricted to the thorax pollinosity and phallic complex morphology. A. atra possess golden pollinosity (fig. 2), basiphallus rounded and postgonite longer than pregonite (fig. 3), while A. femorata has grey pollinosity, basiphallus quadrate in ventral view and postgonite about as long as pregonite (Cherian 1984, fig. 14).
