Abstract
Although the New Zealand ground wētā (Anostostomatidae: Hemiandrus) are widespread and abundant, little has been described of their ecology and behaviour. Within the genus several lineages have evolved with ovipositors that are unusually short for this orthopteran family. Some species with this derived morphological character also exhibit maternal care of eggs and offspring. Two new species are described here, Hemiandrus maia sp. nov. and Hemiandrus electra sp. nov. Although morphologically similar with medium length ovipositors, they are not sister taxa and live at opposite ends of South Island, New Zealand. The behaviour of Hemiandrus maia sp. nov. was studied using burrow door re-construction as a key to activity patterns. Observations at night and burrow excavation during the day were used to identify features of their behaviour. Maternal care of both eggs and nymphs was observed. Hemiandrus maia sp. nov. were shown to eat fruit, invertebrates and seeds without discrimination.http://zoobank.org/urn:lsid:zoobank.org:pub:1C7EB0D2-D01B-4D3A-B643-D17813EC2084
