Specimens examined. (N = 1) [South India] 1♂ ( MHJ), Anamalai Hills, Topslip, V. 1977, C.V. Nidek leg.

Description. Internal sac everted dorso-apically in right lateral view. DA largest in bladders; VA as large as VB, B, BLR and VLR; DLL smallest in bladders.

VA shortly and roundly everted apically, vested with short spines, which are weakly chitinous. VLR roundly everted apically and weakly chitinous. DA well swollen dorsally. DLL roundly swollen right laterally. VB roundly swollen left latero-ventrally, vested numerously with short spines, which are forming a band. BLR roundly swollen left laterally, vested numerously with short spines, which are weakly chitinous. B roundly swollen right laterally. Flagellum very elongate, S-shaped. Medial tooth short and cylindrical, extending left laterally, sinuous at apex.

Remarks. This species shares the characteristics of the position of each bladder with Calochroa assamensis ( Parry, 1844) , but is distinguished by the following characteristics: VA everted apically; DLL not swollen; VB with short spines; medial tooth dextral extending, sinuous.
