Pygofer broad, lobe bearing pair of spinelike distal processes. Subgenital plate slender, with marginal setae on dorsal region, apex with tuft of long setae ( Figs 26, 27 ). Aedeagus tubular, shaft slender with two finely serrate ventrolateral flanges near midlength, bent dorsally, gonopore apical ( Figs 28, 29 ). Dorsal connectives with upper parts falcate, with single point, ventral parts boot-shaped in posterior view ( Figs 30, 31 ).

Diagnosis. This new species resembles V. o bt us a Hamilton in the structure of the pygofer, but may be distinguished from the latter by the serrate rim of the aedeagus in lateral view and the presence of a single projection on the each upper part of the dorsal connective. Etymology. This new species epithet refers to the serrate rim of the aedeagus in lateral view.
