A lowland species whose known distribution ranges from Banks Peninsula to Dunedin. It is in a wide variety of sites under often very different vegetation types, from coastal broadleaf forest and inland Nothofagus forest ...

Holcaspis bathanae
was first found on the dry tussock-shrubland slopes of Mt St Bathans in northwestern Central Otago. 40years later a second population was found in southern Mackenzie basin 50 kms away at Qua...

Holcaspis bessatica, Holcaspis bidentella, Holcaspis abdita, Holcaspis falcis, Holcaspis ohauensis and Holcaspis new species are six rare species that are confined to the Mackenz...

See Holcaspis bessatica

A widespread species in the North Island north of a line joining Mt Taranaki, Ohakune and Napier.

These are relatively small and live in the litter of many types of habitats. Although not tolerant of urban habitats they are often found in Pinus and other plantations where soil has not been disturbed for some t...

A common Mid- and North Canterbury species. It can be recognised immediately by its larger size (though H. suteri and H. hudsoni are similar) and the presence of two cones on the underside of the head close...

Widespread in the North Island.

Although this species is common in the dry Nothofagus solandri forest along the southern shores of Lake Ohau it is not present (so far) in the small patch of forest where Holcaspis bessatica and Holcas...

Of the 37 species in this genus 19 are included here. All are wingless. Most have relatively wide distribution patterns (>100000 ha) but are found only within areas that have not been extensively modified. Yet 2 species ...

A species found only in the Mackenzie Basin but is far more widespread there than the other local endemic Megadromus omaramae. It also occurs in a wide variety of vegetation types: from dry Nothofagus fore...

Known as the "Alexander beetle" to many schoolchildren of Canterbury, where it is common in most urban and agricultural habitats. Females burrow in light soils and form a small chamber at the end. Here the female will la...

This species and M. capito are very close and can not be separated on simple external features. They were once considered to be the same. M. bucolicus is confined to a few islands in the Marlborough Sounds ...

One of New Zealand's outstanding beetles. Its dark green, slightly knobbly back (elytra) enthrall some vistors but its strong jaws may draw blood on the finger when picked up. Although it forms small burrows under logs i...

A rare, dryland species in the loess soils of Marlborough south-east of the Alpine fault (compare Megadromus speciosus) . The is no information on the area between it and its neighbour Megadromus wallacei a...

A relatively small black species known in the subalpine tussock lands of the eastern mountains of Central Otago. It is common on the Rock and Pillar Range.

A Banks Peninsula endemic, it is yet to be found on the western (Port) Hills of the peninsula.

A moderately large, black and uncommon species of North Otago

Most Megadromus species do not cross the Great Alpine fault and three species that do lie only to the west and north form a relatively close group: Megadromus vigil, Megadromus speciosus, Megadr...

A very common species of southestern Otago, Southland and Stewart Island. In Otago it reaches into the Taieri Plains as far north as the Lee Stream. It apparently is absent from the volcanics of the Otago Peninsula and t...

Megadromus omaramae is probably the most restricted of all the species in its genus as it is common in a 5 ha patch of very dry mountain beech forest in the southern part of the Mackenzie Basin near Lake Ohau, and...

A widespread and relatively common species of North Canterbury and inland Marlborough. It coexists with Megadromus rectangulus but is found more in the well drained, often stony habitats under many types of vegeta...

Three species, Megadromus wallacei, Megadromus rectalis and Megadromus rectangulus should be considered together as they share many areas but not discrete habitats. Megadromus rectalis is ess...

Another predatory ground beetle that lives in the southern lowland forests of Fiordland eastwards to the Southland Plains and northwards as far as Lake Hawea. It occurs also at higher altitudes in the central/western mou...

One of the localised species found in NZ. Aparently confined to a single ridge in the Marlborough Sounds mainland and on Arapawa Island. One of the species that lies on the north-western side of the alpine fault.

A small greenish species endemic to South Canterbury. Rather similar in shape, size and habitat to Megadromus rectangulus.

Widespread in the North Island but its most northern populations are probably well separated now by human modifications of the environment. It is tolerant of some human sites around Wellington and the Kapiti Coast. Ther...

Common within forests of the mountains of Mid-Canterbury away from the Main Divide and its higher rainfall. Until recently it was thought to be endemic to this area but now is known from a remnant patch of shrubland nea...

The common species of the stony soils mainly within the coastal forests on the steep slopes of the Kaikoura mountains. See also Megadromus rectalis and Megadromus rectangulus. Yet another black species, ver...

see Neoferonia truncatula. At present the full extent of the distribution of Neoferonia ardua is unknown.

There is a complex of species from Hokitika northwards into the mountains of Northwest Nelson. N. integrata is possibly the most widespread and based on present identifications is distributed from Hokitika, throug...

A species so far known from a few sites in the immediate vicinity of Westport

The two small carabids of this genus in Otago and Southland are very similar in form and colour. However, N. procerula is widespread and found in many lowland remnant forest sites whereas N. edax is rare a...

At present this species is known only by a few specimens probably collected in Fiordland where the related, Neoferonia prolixa is known. It is thought to be a synonym of this name.

Mt Owen is the type locality of this species. It has been confused with and synonymised under Neoferonia ardua as they are similar and occur together on the Mt Arthur range. There are also several similar species ...

This large predatory ground beetle is certainly common in the forests of the lower half of the North Island and especially so in the forests of north-west Nelson and Marlborough Sounds. However it rarely enters urban hab...

Members of Zeopoecilus have not been found with any Megadromus species except on small Stephens Island (see Megadromus bucolicus) and, like Plocamostethus planiusculus, do not cross the Great ...

One of the rarest species of Northwest Nelson mountains and valleys. Its elytra are an iridescent rich dark red and the elytral grooves (striae) are wavy.

A common species of the foothills surrounding Nelson city and in the Motueka River hinterland. (see alsoZeopoecilus calcaratus).
