Abstract
A new genus and three new species of pselaphine staphylinid beetles, supertribe Faronitae, from Western Australia are described as follows: Porongurupgen. nov. is based on Porongurup angulatussp. nov., with the two additional new species, Porongurup clarkeisp. nov. and Porongurup tenuissp. nov. Illustrations of their habitus, and major diagnostic characters as well as a distribution map are included. A key to the species is provided.
Highlights
The supertribe Faronitae consists of 29 genera worldwide, with 13 genera being found in Australia and New Zealand (Park and Chandler 2017)
In the collections of Faronitae being examined as part of a treatment of the fauna of Australia, 31 specimens were segregated into three species that shared a combination of discrete diagnostic characters, with that combination separating them from all other known faronite genera and supporting the creation of a new genus
This new genus can be recognized by the following combination of characters: rostrum with linear frontal sulcus, abdominal segment VI approximately twice as long as V, and the male genitalia have the median lobe of the male genitalia elongate and narrow, culminating in an acute apex
Summary
The supertribe Faronitae consists of 29 genera worldwide, with 13 genera being found in Australia and New Zealand (Park and Chandler 2017). Members of this genus are separated from other faronite genera by the following combination of characters: rostrum with linear frontal sulcus (Fig. 3A); pronotum with median antebasal foveae, outer basolateral foveae, and inner basolateral foveae; prosternum with lateral mesocoxal foveae, and median procoxal foveae (Fig. 3B); mesoventrite with lateral mesosternal foveae and promesocoxal foveae (Fig. 3C); metaventrite with lateral metasternal foveae and lateral mesocoxal foveae (Fig. 3C); length of abdominal tergite and visible sternite VI approximately twice as long as V (Fig. 1); species only known from Western Australia (Fig. 5).
