Description.

See Wang and Liang 2008

Female genitalia. Genitalia symmetrical on both sides, except for endogonocoxal lobe and sternite VII (Fig. 2 A, C ). Anal tube (Fig. 2 A ) symmetrical elongate, with anal styles not exceeding its apex. Gonapophyses VIII (first valvular) (Fig. 2 B, D ) strongly sclerotized, saw-like, with 7 distinct teeth on the dorsal margin, 2 distinct teeth on the ventral margin, numerous small, indistinct teeth along both margins. Gonapophyses IX (second valvula) (Fig. 2 E – G ) reduced, triangular, bilaterally symmetrical, lateral margins somewhat sclerotized, remainder largely membranous. Gonoplace (third valvula) (Fig. 2 B, H ) broad, membranous, with about 12 teeth on the ventral margin and apical margin. Endogonocoxal lobe (Fig. 2 C ) at the base of the gonapophyses VIII produced mesad finger-like on the left side and beak-like on the right side. Posterior margin of sternite VII (Fig. 2 C ) with asymmetrically median triangular projection, the tip of process directed to the left posterior in ventral view.

Remarks.

The female genitalia of this species are similar to those of V. falcata , but can be distinguished by the posterior margin of sternite VII bearing an asymmetrically triangular projection pointing to the left posterior in ventral view (vs a symmetrical median triangular projection, directed to middle posterior in V. falcata ). Additionally, the endogonocoxal lobe has a finger-like protrusion on the left side and a beak-like protrusion on the right side (vs broader paw-like protrusions on the left and slender ones on right side in V. falcata ).
