Mecodema is a genus of large flightless ground beetle (Carabidae) endemic to New Zealand. The genus is very diverse in comparison to the other three New Zealand genera within the subtribe Nothobroscina. Mecodema is the only nothobroscine that is geographically widespread across both the North and South Islands, as well as numerous offshore islands, although a species of Diglymma is found in Wellington.
Jacobsoniidae is a family of beetles. The larvae and adults live under bark, in plant litter, fungi, bat guano and rotten wood. It is a small family with 23 described species in three genera:
Nosodendridae is a family of beetles, with only 67 species in three genera:
Broscinae is a subfamily of ground beetles. It contains the tribe Broscini and the following genera:
Acallistus is a genus of beetles in the family Carabidae, containing the following species:
Diglymma is a genus of beetles in the family Carabidae, containing the following species:
Scirtidae is a family of beetles (Coleoptera). These beetles are commonly referred to as marsh beetles, as the larvae are typically associated with stagnant water, but can be found in flowing water. Adults prefer decomposing plant material near the water's edge. More than an estimated 600 species are known worldwide, distributed among at least 60 genera.
Mecyclothorax is a genus of beetles that contains over 400 described species or subspecies, mostly from the Hawaiian Islands and Tahiti and Moorea, French Polynesia. Additional radiations have evolved in Queensland, Australia, New Guinea and New Caledonia. The genus has been divided into five subgenera: Eucyclothorax Liebherr 2018 of Australia, Qecyclothorax Liebherr 2018 of Queensland, Australia, Meonochilus Liebherr & Marris, 2009 of New Zealand, Phacothorax Jeannel 1944 of New Caledonia, and the more widely distributed subgenus Mecyclothorax Sharp 1903 [in Australia, the Sundas, New Zealand, the Society Islands, and Hawaii]. The adelphotaxon to Mecyclothorax is hypothesized to consist of the genera associated with Amblytelus Blackburn, also distributed in Australia, and therefore the evolutionary history of Mecyclothorax commenced in Australia.
Ctenognathus is a genus of beetles in the family Carabidae. This genus is endemic to New Zealand. It was first described by Léon Fairmaire in 1843.
Psydrinae is a subfamily of beetles in the family Carabidae.
Selenochilus is a genus of beetles in the family Carabidae, endemic to New Zealand, including the following seven species:
Pterostichinae is a subfamily of ground beetles. It belongs to the advanced harpaline assemblage, and if these are circumscribed sensu lato as a single subfamily, Pterostichinae are downranked to a tribe Pterostichini. However, as the former Pterostichitae supertribe of the Harpalinae as loosely circumscribed does seem to constitute a lineage rather distinct from Harpalus, its core group is here considered to be the present subfamily and the Harpalinae are defined more narrowly.
Holcaspis is a genus of beetles in the family Carabidae, endemic to New Zealand.
Megadromus is a genus of beetles in the family Carabidae, containing the following species:
Scaritinae is a subfamily of beetles in the family Carabidae, containing the following genera:
Nesamblyops is a genus of beetles in the family Carabidae, containing the following species:
Kiwitachys is a genus of beetles in the family Carabidae, containing the following species:
Oopterus is a genus of beetles in the family Carabidae, containing the following species:
Zolus is a genus of beetles in the family Carabidae, containing the following species:
Bembidiini is a tribe of ground beetles in the ground beetle family, Carabidae. There are at least 440 described species in Bembidiini.
