Description of the larva of Catadromus lacordairei Boisduval, 1835 (Coleoptera: Carabidae), a threatened carabid, from Tasmania, Australia.

The carabid beetle genus Catadromus MacLeay (Coleoptera: Carabidae) is endemic to the Australasian region. Of the five currently recognised species, only one, C. lacordairei Boisduval, 1835 occurs in Tasmania, Australia, where it is listed as a threatened species on the Tasmanian Threatened Species Protection Act 1995. In the present paper, we describe and illustrate the larva of C. lacordairei, providing the first detailed larval description of a member of this genus.

Descriptions and key to the larvae of the Tasmanian endemic genus Hoplogonus Parry (Coleoptera: Lucanidae), and comparison with the sympatric Lissotes rudis Lea.

The stag beetle (Coleoptera: Lucaindae) genus Hoplogonus Parry is endemic to northeastern Tasmania and contains three recognised species. Descriptions of the imagines have been published previously, but not the larvae. Descriptions of the larvae of the three Hoplogonus species and the sympatric Lissotes rudis Lea (also Lucanidae) are presented and discussed, and a key to aid identification of Hoplogonus larvae is included. The classification of Hoplogonus within the tribe Platycerini is proposed, alongside Lissotes.
