Larval morphology of Crephelochares and Peltochares (Coleoptera: Hydrophilidae)

The larval morphology of Crephelochares Kuwert, 1890 and Peltochares Régimbart, 1907 is described in detail based on specimens of C. abnormalis (Sharp, 1890) and P. atropiceus (Régimbart, 1903) collected in Taiwan; the chaetotaxy of the head capsule and head appendages of both genera is…
