Contents: 25 species, of which 19 (76.0%) are endemic.
Remarks: Previously included Trimerodytes balteatus. Some authors have regarded Parahelicops as a synonym of Opisthotropis (e.g., Smith 1943; Brown & Leviton 1961; Zhao, Jiang & Huang 1978; Cox 1991; Cox, van Dijk, Nabhitabhata & Thirakhupt 1998). The origin and distribution of the type species of this genus, Opisthotropis ater, remains obscure (see remarks under ater). David, Pham, Nguyen & Ziegler (2011) pointed out that the grammatical gender of Opisthotropis is feminine.
Distribution: SE. Asia, Malay Archipelago.
