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

Remarks. This species shares the characteristics of the position of each bladder with Calochroa hamiltoniana but is distinguished from the latter by the following characteristics: VA everted ventro-apically; DLL with weakly chitinous spines; VB with long spines; medial tooth straight.
