Supplementary description.

Male terminalia directed dorsally. Tergite 9 fused with gonocoxite and sternite 9 (Fig. 32C ); caudal margin of tergite 9 with small, rounded lateral lobe both ventral and lateral view (Fig. 32A, C ); posterior margin U- or V-shaped. Sternite 9 reduced to narrow band (Fig. 32B, C ). Gonocoxite 1.2-1.3 × longer than tergite 9; ventral lobe relatively small, rounded (in dry specimen looks more finger-like) (Fig. 32B ); apical lobe indistinct; inner surface of gonocoxite sclerotised, with few hairs, without evident modifications. Gonostylus comparable large and complex, with a subapical tooth on outer margin; additional two or three smaller teeth basally (Fig. 32A, C ). Aedeagus complex 1.2-1.3 × longer than gonocoxite in lateral view (Fig. 32C ); ejaculator apodeme large, not covered by paramere in lateral view (Fig. 32F ); interbase seems flat and wide, with a small dorsal tooth in lateral view (Fig. 32F ); interbase directed dorso-laterally, with a deep notch on tip in dorsal view (Fig. 32D, E ); dorsal lobe between interbases indistinct or absent (Fig. 32D ); aedeagus half as long as entry aedeagus complex; aedeagus trifid, straight; median branch longer than lateral branches (Fig. 32D-F ), with a triangular dorsal outgrowth; tip slightly bifid or trifid, depend on angle (Fig. 32A ); lateral branches slightly curved laterally in dorsal and ventral view (Fig. 32D, E ); tips of branch widened dorsally; sperm ducts branching from short elongation of sperm pump; branching area dark (Fig. 32D-F ).

Female terminalia: Tergite 8 posterior part membranous, with few hairs, but not divided medially (Fig. 33A ); wider than tergite 9 in lateral view (Fig. 33B ). Tergite 10 with small, slightly separated median lobe in middle of posterior margin (Fig. 33A, B ); covered with short hairs. Triangular sclerite widely fused with tip of tergite 10; tergite 10 without lateral lobe (Fig. 33B ). Cercus elongated blade, with dorsal margin with weakly serrate margin (Fig. 33B ). Hypogynial valve wide and long, dorsal margin close to tip with tooth-like lobe, directed caudally (Fig. 33B, C ). Common spermathecal duct short or indistinct; sperm ducts simple, without distinct pattern, tapering proximally (Fig. 33D ); three spermathecae elongated, with straight duct (Fig. 33E ).
