Valve and subgenital plates fused to form a median plate with a median slit extending almost 0.5 length of plate, with marginal row of macrosetae and a pair of caudal sclerotized lobes. Style with equally developed anterolateral and anteromesal angles, preapical lobe welldeveloped, apophysis long, with strong transverse rugulae, of uniform width and distally rounded. Connective Yshaped, with stem short, arms long, in contact with each other anteriorly.

Remarks
:
X. ankusha
differs from other species of
Xenovarta
in having entire, conically produced pygophore and spatulate, medially twisted aedeagal shaft. It is not closely related to any of the included species in the genus though it shares the characters of the male pygophore with
X. compressa
