Family Anisolabididae
Adults in this family are usually dark and wingless, with the Tasmanian species often without any elytra or are rudimentary only. Males have the forceps asymmetrical, where usually the right arm is curved in more – Gonolabis tasmanica is a montane Australian endemic where the male has the forceps so unevenly twisted as to appear erroneously formed. In the females the forceps are symmetrical and similarly formed. Anisolabididae genera represented in Tasmania include Anisolabis, where the males have the abdomen dilated in the mid section, and Euborellia and Gonolabis where the abdomen widens towards the apex.
