Abstract

The New Zealand Harpalini fauna (Coleoptera: Carabidae: Harpalinae) is revised. Twenty genera and fifty-seven species are recognised. Five new genera are described: Maoriharpalus new genus and Tuiharpalus new genus (Anisodactylina), Hakaharpalus new genus and Kupeharpalus new genus (Pelmatellina), and Kiwiharpalus new genus (Stenolophina). The species Parabaris gourlayi Britton, 1964 is transferred to Tuiharpalus new genus. The original combination Harpalus australasiae Dejean, 1829 is reinstated. Tachys (?) cavelli Broun, 1893 is transferred to the genus Hakaharpalus. Twenty-three new species are described: Anisodactylina — Allocinopus belli new species, A. bousqueti new species, A. wardi new species, Maoriharpalus sutherlandi new species, Parabaris hoarei new species, P. lesagei new species, Tuiharpalus clunieae new species, T. crosbyi new species, T. hallae new species, T. moorei new species; Pelmatellina — Hakaharpalus davidsoni new species, H. maddisoni new species, H. patricki new species, H. rhodeae new species, Kupeharpalus barrattae new species, K. embersoni new species, K. johnsi new species, Lecanomerus marrisi new species, Syllectus gouleti new species; Stenolophina — Kiwiharpalus townsendi new species, Pholeodytes helmorei new species, P. nunni new species, and P. palmai new species . Eight new synonymies are established (valid name listed after equal sign): Allocinopus ocularius Broun, 1908 = Allocinopus sculpticollis Broun, 1903; Allocinopus castaneus Broun, 1912 = Allocinopus smithi Broun, 1912; Hypharpax abstrusus Bates, 1878 = Hypharpax australis (Dejean, 1829); Lecanomerus fallax Broun, 1880 = Lecanomerus insignitus Broun, 1880; Lecanomerus fuliginosus Broun, 1880, Lecanomerus pallipes Broun, 1894, and Lecanomerus incertus Broun, 1914 = Lecanomerus latimanus Bates, 1874; Syllectus spelaeus Britton, 1964 = Syllectus magnus Britton, 1964. Lectotypes are designated for the following taxa: Allocinopus smithi Broun, 1912; A. castaneus Broun, 1912; A. latitarsis Broun, 1911; Euthenarus brevicollis Bates, 1874; E. puncticollis Bates, 1874; Gaioxenus pilipalpis Broun, 1910; Harpalus antarcticus Laporte de Castelnau, 1867, H. novaezelandiae Laporte de Castelnau, 1867, Hypharpax abstrusus Bates, 1878; Lecanomerus fallax Broun, 1880; L. obesulus Bates, 1878; Syllectus anomalus Bates, 1878; Triplosarus fulvescens Bates, 1874. Four adventive species are recorded for New Zealand for the first time: Gnathaphanus melbournensis (Laporte de Castelnau, 1867); Notiobia quadricollis (Chaudoir, 1878); Euthenarus bicolor Moore, 1985; E. promptus (Erichson, 1842).

A concise revision of the taxonomy of all taxa is provided. Subtribes, genera, and species are keyed. Descriptions are provided with illustrations emphasising the most important diagnostic features of the external morphology and male genitalia. Information is given on synonymy, type data, material examined, geographic distribution, ecology, biology, dispersal power, and collecting techniques. The composition of the New Zealand Harpalini fauna, with endemism levels of 55% for genera and 75% for species, and its affinities with Australia, New Caledonia, Lord Howe Island, and Norfolk Island are analysed and discussed. Over 50% of native taxa (25 out of 42 species) are known from 10 populations or fewer and may be of potential conservation concern.
