Clinotanypus Kieffer

( Figs. 1–3 )

Three species of Clinotanypus have been described from the region: C. crux (Wiedemann) and C. obscuripes (de Meijere) from Indonesia as adults by Johannsen (1931), and in their immature stages by Zavrelˇ (1933). Kieffer (1924) described C. pictidorsum from Java.

Larval Clinotanypus cannot be differentiated yet and the only regional rearings known are pharate pupae. The known biologies within this essentially tropical genus suggest that the larvae are predatory, eurythermic and tolerant of organic pollution. The two larval records in this study come from dilute ponds with low conductivities (103, 194 µS. cm−1) and low dissolved solids (65, 97 ppm).
