A new species ofHyphydrusIlliger 1802 (Coleoptera Dytiscidae) from West New Guinea, and notes on other species of the genus

Abstract

Hyphydrus dani n. sp. is described from the highlands of West New Guinea. This species is probably the sister species of H. elegans (Montrouzier 1860). In addition, collecting notes on H. dani and H. lyratus Swartz 1808 are provided. The latter is reported from Bali, Lombok, Flores and Ceram for the first time, and the Balinese locality represents the first report of the species from paddy field waters. Faunistic data on H. decemmaculatus Wehncke 1877 and H. elegans as well as notes on the type material of H. curvipes Régimbart 1892 and of H. gibbicollis Régimbart 1892 are reported.
