Mecodema puiakium is a ground beetle of the family Carabidae, endemic to New Zealand. [1]
Mecodema punctellum is a presumed-extinct species of ground beetle of the family Carabidae, endemic to Stephens Island in New Zealand.
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 geographically widespread across both the North and South Islands, as well as numerous offshore islands, including the Three Kings Is., Poor Knights Is., Aotea and Hauturu, Kapiti Is., Stephens Is., Stewart Is., Chatham Is., Snares Is.
Mecodema oconnori is a large-bodied species of ground beetle that is found mainly on the western regions of the North Island, New Zealand. It is mainly found in native forest habitats, both intact and fragmented, and on the edges of pine plantations. Mecodema oconnori ranges from Otaki, Kapiti Coast to Raglan, but is also found in the Manawatu Gorge and some other eastern localities.
Mecodema antarcticum is a carnivorous carabid beetle that burrows in sand above the high tide mark on New Zealand sandy beaches. First described by Francis de Laporte de Castelnau in 1867 as Brullea antarctica, it has since been reassigned to Mecodema.
Mecodema aoteanoho is a medium-sized ground beetle, the only such beetle endemic to Great Barrier Island (Aotea), Hauraki Gulf, Auckland, New Zealand. Mecodema aoteanoho is a sister species to M. haunoho and is closely related to the Coromandel (mainland) species, M. atrox, all of which are species within the monophyletic curvidens group. There are a number of other characters that distinguish M. aoteanoho from all other North Island Mecodema, especially the pattern of the striations on the elytra.
Mecodema tenaki is a species of ground beetle found in the Cape Reinga region, Northland, New Zealand.
Mecodema ponaiti is a species of ground beetle endemic to the Poor Knights Islands, Northland, New Zealand.
Mecodema manaia is a medium-sized ground beetle species found in the native forests of Bream Head and Mt Manaia, Northland, New Zealand. This species shares the forests of Bream Head with a large-bodied species, Mecodema tewhara, with both inhabiting slightly different forest type.
Mecodema argentum is a large-bodied ground beetle found in the northern region of the Coromandel Range, New Zealand and relatively abundant in the hills above Coromandel town. Mecodema argentum is more closely related to Mecodema species found in Northland, than other species found in the Coromandel Ranges. The entire body is black, but the legs and coxae may be reddish brown, plus M. argentum can be distinguished from other North Island Mecodema by the form of the apical portion of the penis lobe.
Mecodema atuanui was described from a single male specimen collected in pitfall traps on Mount Auckland (Atuanui), Kaipara Region. It is a medium-length ground beetle that is related to Mecodema spiniferum, which is the only large-lengthed ground beetle species found in the Waitākere Ranges, Auckland, rather than the more geographically close species to the east in Puhoi.
Mecodema atrox is a medium-sized ground beetle species that is closely related to Mecodema curvidens. Mecodema atrox is relatively rare in comparison due to its preferred habitat, the coastal broadleaf forests of the Coromandel Peninsula, a forest type that is in decline. The body of Mecodema atrox is black and the legs are dark reddish-brown. They can be distinguished from other Mecodema species by a number of characters, including the pattern of asetose punctures along the elytral striae.
Mecodema curvidens Broun is a medium-bodied ground beetle that is geographically widespread throughout the central areas of the North Island, New Zealand, which includes the entomological regions of Auckland (AK), Waikato (WO), Coromandel (CL), Bay of Plenty (BP), Taupo (TO), Rangitikei (RI), Whanganui (WI), Hawkes Bay (HB) and Wellington (WN). Recently, the species M. occiputale Broun was synonymised under M. curvidens. Mecodema curvidens is relatively common through its range except in the southern area of the Hunua Ranges (Auckland) and Wellington regions.
Mecodema quoinense is a large-bodied ground beetle of the genus Mecodema, an endemic New Zealand carabid, which is found in the Tararua Ranges, North Island above about 1000 m. It is named after the type locality Mount Quoin, but specimens have been found on Mount Holdsworth. This species can be distinguished from other Mecodema species by the very distinctive shape of the male genitalia, but it can be differentiated from the other more common Tararua Ranges species, M. simplex, by the narrower/square-shaped pronotum, and the smooth carina of the pronotum.
Mecodema dunnorum is a large-bodied ground beetle in the Mecodema genus found in some native forest remnants in the Puhoi area, north Auckland, New Zealand. It is one of six endemic Mecodema species that are found in the Auckland entomological region, as per Crosby et al. 1976.
Mecodema kipjac is a large-bodied ground beetle species found near Kirikopuni in Northland, New Zealand.
Mecodema jacinda is a large-bodied ground beetle endemic to Maungatautari Sanctuary, Waikato, New Zealand. It is the largest species of Mecodema found on Maungatautari, which also has the medium-sized M. curvidens inhabiting the forest. It is named after former New Zealand Prime Minister Jacinda Ardern.
Mecodema moniliferum is a medium-sized ground beetle endemic to the South island, New Zealand. This species is part of the monophyletic curvidens group and is found on the braided-river systems of the South Island.
Mecodema howitti, termed the Large Banks Peninsula ground beetle, is a carnivorous forest ground beetle in the genus Mecodema. It is endemic to Banks Peninsula, Canterbury, New Zealand, and is the largest of the 16 carabids found in the area.
Mecodema crenicolle is an endemic species of ground beetle from New Zealand.
Mecodema scitulum is a species of endemic New Zealand flightless beetle in the family Carabidae. It was first described by Thomas Broun, in 1984, from a single specimen that he received from the Edwin Mitchelson. This species then became a junior synonym of Mecodema spiniferum after Everard B. Britton completed his revision of the New Zealand Broscini in 1949. Like Broun, Britton based this synonymy on the only specimen available, the holotype, because of the confusion surrounding the type locality where M. scitulum was collected from. However, D.S. Seldon and T.R. Buckley (2019) reinstated the species M. scitulum based on the morphological comparisons of 30+ specimens with the holotype and molecular analyses.
