Idiops harti – Raven 1985: 158 . Diagnosis The female of Idiops harti differs from that of other species of the genus by having the spermathecae with short ducts (same length as the diameter of the receptacula) and a well-marked division between them, by having the receptacula shaped like a bean ( Fig. 22 ) and by having only an internal row of large teeth on the chelicera ( Fig. 5C ).
