Abstract
A new family is established for the New Zealand genera Chalcodrya, Philpottia, and Onysius (= Malacodrya) and the Tasmanian genus Sirrhas (= Notolea syn. nov.). In adult characters Chalcodryidae shows close affinities with Perimylopidae, but the larvae differ in several important respects. The family is defined on adult and larval characters. All genera and species are keyed and described, including Chalcodrya hilaris sp. nov. and Philpottia levinotis sp. nov. The following new synonymy is established: Philpottia mollis (Broun, 1886) = P. maculata Broun, 1915. Onysius anomalus Broun, 1886 = O. pulcher Broun, 1893. Sirrhas limbatus Champion, 1893 = Notolea limbata Carter, 1915. A group of proclinate, blunt-tipped chemosensory setae, forming a probable olfactory organ, is recorded on the dorsal surface of the terminal segment of the maxillary paIp. These chemosensory setae seem to be present in various positions in the maxillary palpi of nearly all Coleoptera, but apparently have not been recorded before.
