Description. Internal sac everted dorso-apically in lateral view. DA largest in bladders; VA, VLR and VB same in the large; BLR, B and DLL slightly swollen.

VA roundly everted right latero-ventrally, vested with short and weakly developed spines. VLR roundly everted apically, vested with short and weakly developed spines. DA semicircular, swollen dorsally. DLL roundly swollen. VB roundly everted ventrally, vested numerously with long spines, which are forming a spot. BLR roundly everted left laterally, vested numerously with short spines, which are forming a band. B oval, swollen right laterally. Flagellum very long and thin, S-shaped. Medial tooth straight extending apically.

Remarks. This species shares the characteristics of the position of each bladder with Calochroa fabriciana but is distinguished from the latter by the following characteristics: VA long, swollen ventro-apically; DLL without spines; medial tooth extending apically.
