Diagnosis.

The species is morphologically similar to Sinocallipus catba from which it can be distinguished by its larger body, a gonocoxal process g that is more than 3 × the length of process k, a differently shaped trochanteral process of leg 9 in males, and paraprocts divided into two, nearly equal-sized sclerites (Stoev and Enghoff 2011).

Remarks.

The species was described originally from three caves situated in the region of Phong Nha and Cha Noi communes in Quang Binh Province. It is now reported from another cave (Tu Lan), located approximately 15 km northeast from the other localities at Cha Noi.
