Schizoptera (Odontorhagus) stricklandi China 1946: 25 , 152 (orig. descr.).

Diagnosis. Distinguished among species of Schizoptera (Odontorhagus) by the flat head, the weakly asymmetrical subgenital plate, the small, undifferentiated triangular process of the subgenital plate, the serrated right conjunctival appendage, the thin and tapering stem of the right paramere, and the heart-shaped dorsal fold of the anophore.
