A review of the Cholevinae from the island of Borneo (Coleoptera, Leiodidae)

Menno Schilthuizen et al. Zookeys. .

Abstract

The available knowledge of the round fungus beetle subfamily Cholevinae (Leiodidae) from the island of Borneo is reviewed, and the results of newly studied material presented. The currently known 30 species (of which 14 are newly described herein) represent the genera Micronemadus (one species), Catops (one species), Baryodirus (one species), Ptomaphaginus (14 species), and Ptomaphaminus (13 species). The following new species are described: Micronemadussondaicus Schilthuizen & Perreau, sp. n., Ptomaphaginusgrandis Schilthuizen & Perreau, sp. n., P.louis Schilthuizen & Perreau, sp. n., P.muluensis Schilthuizen & Perreau, sp. n., and P.isabellarossellini Schilthuizen, Njunjić & Perreau, sp. n., and Ptomaphaminuskinabatanganensis Njunjić, Schilthuizen & Perreau, sp. n., P.testaceus Schilthuizen & Perreau, sp. n., P.nanus Schilthuizen & Perreau, sp. n., P.marshalli Schilthuizen & Perreau, sp. n., P.hanskii Schilthuizen & Perreau, sp. n., P.sarawacensis Schilthuizen & Perreau, sp. n., P.layangensis Schilthuizen & Perreau, sp. n., P.microphallus Schilthuizen & Perreau, sp. n., and P.alabensis Schilthuizen & Perreau, sp. n. It is expected that the cholevine biodiversity of Borneo is still far from completely known. Nonetheless, provisional identification keys to all species known so far are presented.

Keywords: Indonesia; Malaysia; caves; scavenging beetles; taxonomy.
