| Hemiandrus spp. in Trewick, Taylor-Smith & Morgan-Richards, 2020. |
Wētā (Orthoptera: Anostostomatidae) are a well-recognised component of New Zealand nocturnal ecology, but much of the diversity remains undescribed and only partly characterised. Species of Hemiandrus conceal themselves during the day in soil burrows and most are infrequently encountered, however, one taxon is notorious in some South Island vineyards. We demonstrate that this wētā at unusually high density in some vineyards in the Awatere valley is also found in North Island forests (Hemiandrus bilobatus). Here we use morphological and genetic data to identify the wine wētā and examine its ecology in vineyards. We also describe four new species which belong to the same ground wētā clade as the wine wētā. We provide mtDNA analysis and diagnostic morphological characters to distinguish six Hemiandrus species that are characterised by adult females having an extremely short ovipositor and maternal care.

| Modification of sternite 6 (S6) in adult females of two described short-ovipositor Hemiandrus ground wētā. Hemiandrus bilobatus: A–B, Awatere (GW1160); C, Mana (GW652); D, Awatere (GW1225). Hemiandrus pallitarsis: E–F, Karori Wellington with typical S6 (GW1140); G–H, Karori with unusual additional S5 modification (GW1139). |
Hemiandrus taygete sp. nov.
Etymology: The golden horns of the doe, into which the Pleiad Taygete was transformed by Artemis, resemble the sternite lobes of females in this species.
Hemiandrus sterope sp. nov.
Etymology: Sterope (lightning), one of the Pleiades sisters. The males of this species produce the most rapid premating drumming of all species of this genus studied (Gwynne 2004).
Hemiandrus merope sp. nov.
Etymology: Merope, faintest of the Pleiades (sometimes referred to as the ‘lost Pleiad’ because she was at first not seen by astronomers or charted like her sister stars). The female of this species has the faintest (missing) structures on her sixth sternite.
Hemiandrus celaeno sp. nov.
Etymology. Celaeno, the dark one of the Pleiades sisters.
