Larivière M-C, Larochelle A. 2022. Synopsis of the subfamily Carventinae in New Zealand (Heteroptera: Aradidae). Insecta Mundi 0961: 1–54.
The subfamily Carventinae (Heteroptera: Aradidae) is revised for New Zealand. Eight genera and fifteen species are recognized.
One genus and six species are described as new: Carventaptera hallae Larivière and Larochelle new species, Lissaptera heissi Larivière and Larochelle new species, Modicarventus kirmani Larivière and Larochelle new species, Neocarventus montanus Larivière and Larochelle new species, Neocarventus northlandicus Larivière and Larochelle new species, Neocarventus potterae Larivière and Larochelle new species, Tuataraptera Larivière and Larochelle new genus.
One new combination is established: Neocarventus uncus Kirman, 1989 = Tuataraptera unca (Kirman, 1989).
One new synonymy is made: Leuraptera yakasi Heiss, 1990 = Leuraptera zealandica Usinger and Matsuda, 1959.
A revision of all taxa is provided. Descriptions, identification keys, illustrations of male genitalia, habitus photos, distributional data and maps are given. Extensive information on biology is included for each species.
The subfamily Carventinae (Heteroptera: Aradidae) contains 118 genera and 364 species (C. Damken, pers. comm.). This is primarily a tropical group of mostly flightless Aradidae; only seven genera are known to be macropterous (Schuh and Weirauch 2020). In New Zealand, Carventinae are mostly found in warm-temperate rainforests with their greatest diversity in northern areas of the North Island where subtropical forests persisted the longest over geological time. Six of eight genera and all known species are endemic to the country.
Most species live on the moist, often moldy bark (with or without visible wood-decay fungi) on the underside of rotting fallen branches and logs lying on the forest floor. Species of Carventaptera Usinger and Matsuda can also occur under the bark of decaying branches and logs. Species of Acaraptera Usinger and Matsuda, and Lissaptera Usinger and Matsuda, mostly occur in leaf and twig litter.
