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.
Highlights
Wilkinsonellus Mason, 1981 are parasitoid wasps within Microgastrinae (Braconidae: Hymenoptera) of Pantropical distribution
The genus currently contains 19 species (Table 1), of which three species were recently reported in the Neotropics (Arias-Penna et al 2013)
The identity of hosts parasitized by those wasps remains essentially undocumented
Summary
Wilkinsonellus Mason, 1981 are parasitoid wasps within Microgastrinae (Braconidae: Hymenoptera) of Pantropical distribution. This paper provides descriptions of the three new Wilkinsonellus species, representing the first records of this genus in Fiji and establishing this island country as the easternmost distribution of the genus in the Indo-Pacific Region so far. This revision elevates the current total of Wilkinsonellus species known worldwide to 22. First record of the genus Wilkinsonellus (Hymenoptera, Braconidae, Microgastrinae)... 27
