Specimens examined. (N = 1) [Laos] 2♂♂ (MHJ), Savannakhet, Ing Hang Strupa Forest, 25. VI. 2014, M. Hori leg.

Description. Internal sac everted apically in lateral view, parallel to median lobe. DA and VA largest in bladders; B same as large as BLR; VB and DLL slightly swollen. VLL exist.

VA roundly everted ventro-apically, vested with short spines, which are weakly chitinous. VLL roundly everted ventrally. DA roundly swollen right dorsally. DLL roundly swollen right laterally, covered numerously with fine spines, which are weakly chitinous. VB roundly everted ventrally, vested numerously with short spines, which are weakly chitinous and forming a band. BLR roundly everted left latero-dorsally, vested numerously with short spines, which are weakly chitinous. B roundly swollen right latero-dorsally, vested numerously with short spines, which are weakly chitinous.

Flagellum very long and thin, S-shaped. Medial tooth long and dextral extending, tapered.

Remarks. Among the examined species in this study, we could not find any species with common internal sac. This species is clearly distinguished from other members of Calochroa by the following characters: internal sac everted apically in lateral view, parallel to median lobe.
