Arthorpoda of the subantarctic islands of New Zealand (1) Coleoptera : Carabidae Southern New Zealand, Patagonian, and Falkland Islands Insular carabidae

Abstract

Diagnoses are given for carabids of the Migadopinae, Trechinae, and Zolinae occurring on the islands to the south of New Zealand. Two Patagonian and Falkland Islands species are included and a New Zealand species is synonymised under one of them. A new species from the Snares Islands is described, as are the larvae and pupae of some species.

The beetle (Coleoptera) fauna of the Antipodes Islands, with comments on the impact of mice; and an annotated checklist of the insect and arachnid fauna

“…'Distribution' Refers to the localities in addition to the Antipodes Islands from which the species is known. Johns (1974) noted the ability of adults and larvae of this species to live under seawater, and thus the possibility of their transoceanic dispersal The adult is illustrated (as Kenodactylus capito Broun) in Darlington (1964) and the larva in Johns (1974) Loxomerus new species First record New record Origin Endemic Comments Adults and larvae were collected from Bollons Island from under tussock mats and rocks P M Johns (pers comm 1999) collected the remains of dead specimens from one site on the North Plains, Antipodes Island No live specimens have been collected from Antipodes Island Loxomerus n sp is very similar to Loxomerus brevis (Blanchard) from the Auckland Islands The Antipodes Islands species differs most obviously in its brown colouration and has more parallel-sided elytra with more deeply impressed striae, a more constricted pronotal base, and a smoother dorsal surface to the head Johns (1974) commented that Antipodes Island specimens were confined to low stony areas associated with penguin colonies or seal haul-outs The adult is illustrated (as Oopterus tarsahs (Broun)) in Darlington (1964) Ordish (1984) recorded M. campbellensis from among littoral debris and bird nesting material on Campbell Island and from porous rock on the Antipodes Islands. The adult is illustrated in Gressitt and Samuelson (1964a) and the larva is illustrated in Samuelson (1964).…”

The significance of the sub-Antarctic Kerguelen Islands for the assessment of the vulnerability of native communities to climate change, alien insect invasions and plant viruses

“…During the 1970s, a period of rising air temperature had a major influence on the establishment of C. vicina populations on the Kerguelen Islands, facilitating the successful completion of this species' life cycle. Individuals of C. vicina originating from (Darlington 1970;Johns 1974). This species was first observed on the Kerguelen Islands in February 1939 (Jeannel 1940), but was probably introduced at one site in 1913 (Port Couvreux, see Fig.…”

Physiological responses to temperature in Merizodus soledadinus (Col., Carabidae), a subpolar carabid beetle invading sub-Antarctic islands

“…To date, six insect species are invasive in the Kerguelen Islands, five of them being cosmopolitan species with widespread worldwide range or temperate origin (Frenot et al 2005). So far, only the ground beetle Merizodus soledadinus Guérin-Méneville (Col., Carabidae) originates from a native area restricted to about the same latitude as the Kerguelen Islands, in the cold southern temperate area (Patagonia, Tierra del Fuego and Falkland Islands;Jeannel 1940;Johns 1974;Chevrier 1996;Roig-Junent and Dominguez 2001;Convey et al 2011). In the recipient environment, this flightless predaceous insect has encountered biotic (prey communities and their distribution) and abiotic conditions (cooler temperatures) that differ from its native area.…”
