Supplementary description.

Male terminalia: Medium sized and relatively simple, directed caudally. Tergite 9 fused with gonocoxite (Fig. 17C View Figure 17 ). Tergite 9 posterior margin convex in dorsal view (Fig. 17A View Figure 17 ), lateral lobe very small, triangular, ~ 1/4 ×total length of tergite 9 in lateral view (Fig. 17C View Figure 17 ); covered with relative long setae; posterior margin of tergite 9 with subhyaline, ventrally directed plate, next to lateral lobe; shape approximately triangular, covered with short pale setae (Fig. 17A View Figure 17 ). Sternite 9 fused with tergite 9 and gonocoxites, present as a narrow but continuous ring (Fig. 17A-C View Figure 17 ). Gonocoxite longer than tergite 9 in lateral view. Ventral lobe of gonocoxite well visible, without deep separation from gonocoxite (as in D. caudata and D. glabrata ); inner half pale, partly membranous, covered by long pale hairs (Fig. 17B View Figure 17 ); apical lobe very small, mostly bare; inner part of gonocoxite forming a plate with hairs on all surface (Fig. 17D View Figure 17 ). Membranous area between gonocoxites reach base of ventral lobe (Fig. 17B View Figure 17 ). Gonostylus simple, without lobe in inner side; claw-like in lateral view (Fig. 17D View Figure 17 ); widened in middle length in caudal view (see Fig. 17E, F View Figure 17 from different angles), with small, rounded bulge in inner ventral base (Fig. 17E View Figure 17 ). Sperm pump and ejaculatory apodeme large, partly covered by paramere in lateral view (Fig. 17I View Figure 17 ). Dorsal lobe between interbases dorso-ventrally flattened, posterior margin almost straight, covered by dense short hairs (Fig. 17G, I View Figure 17 ); interbase simple, with a few hairs, curved dorsally, without ventral projection, (Fig. 17I View Figure 17 ). Aedeagus bifid, branches short, slightly curved dorsally; base wide, evenly narrowing to tip in lateral view (Fig. 17I View Figure 17 ).

Female terminalia: Brown, tip of cercus and hypopygial valve yellowish brown. Tergite 8 separated at middle by membranous area (Fig. 18A View Figure 18 ). Tergite 8 larger than tergite 9 in lateral view (Fig. 18B View Figure 18 ). Ventral corner of tergite 9 not rugged, with few hairs (Fig. 18B View Figure 18 ). Triangular sclerite separated from tip of tergite 10, but close situated (Fig. 18A View Figure 18 ). Lateral lobes of tergite 10 finger-like with few long hairs (Fig. 18A View Figure 18 ). Cercus and hypogynial valve simple, wide, blade-shaped, tips rounded (Fig. 18B View Figure 18 ). Dorsal apical surface of cercus rough, formed by few, blunt pyramid teeth (Fig. 18B View Figure 18 ). Sternite 8 simple, without transverse creases (Fig. 18B, C View Figure 18 ). Two very large, elongated spermathecae present with duct almost straight (Fig. 18D View Figure 18 ). Two sperm ducts simple, without any clear markings, genital fork with a rod-shaped median part, posterior part pale (Fig. 18C View Figure 18 ).
