A new Dermatohomoeus from the Ulu Temburong forest, Brunei (Coleoptera, Leiodidae)

'Taxon expeditions' are field courses/expeditions for mixed teams of scientists, students and lay people with the aim to do biodiversity inventories, particularly of cryptobiota and to discover and describe new species.

During a taxon expedition to the Kuala Belalong Field Studies Centre and surrounding area of the Ulu Temburong Forest in Brunei, leaf litter sampling yielded a specimen of a previously unknown species of the round fungus beetle genus Dermatohomoeus Hlisnikovský (Leiodidae, Leiodinae, Pseudoliodini). Using the limited time and facilities available, a scientific description was prepared by a number of the expedition participants. The new species is described, pictured and compared with related species from South and Southeast Asia.
