Aspects of the biology and habits of the broad-toothed stag beetle, Lissotes Iatidens (Westwood 1871) (Coleoptera: Lucanidae) an endemic Tasmanian species

摘要

The Broad-toothed Stag Beetle, Lissotes latidens (Westwood, 1871) belongs to a large genus of flightless lucanid beetles confined to south-eastern Australia, containing 29 described species, 25 of which are endemic to Tasmania (Hangay & De Keyzer 2017). Many of the Tasmanian Lissotes spp. are range-restricted. One of these, L latidens, occupies an area of about 437 km~2, bordered by Orford, Copping and Nugent in south-eastern Tasmania and also occurs within a 6 km~2 area on northern Maria Island. The species is listed as endangered on the Threatened Species Protection Act 1995 due to its restricted distribution, low population density and habitat loss (Invertebrate Advisory Committee 1994).
