First record of the genus Wilkinsonellus (Hymenoptera, Braconidae, Microgastrinae) from Fiji with description of three new species

Abstract

Wilkinsonellus Mason is a relatively small Pantropical genus of braconid parasitoid wasps within the subfamily Microgastrinae. Most of the currently described species are from the Palaeotropics; however, previous records were absent from Fiji. Here, the first three Wilkinsonellus species from Fiji are described: Wilkinsonellus corpustriacolor sp. n., Wilkinsonellus fijienis sp. n. and Wilkinsonellus nescalpura sp. n. The material was collected by Malaise traps set up in a quite variety of ecosystems (wet zone, dry zone and coastal forests) throughout the archipelago. With these records, Fiji represents the easternmost known distribution of the genus in the Indo-Pacific Region. A key to all of the currently known Wilkinsonellus species is included to facilitate species identification. © D.C. Arias-Penna et al.
