Subadult of Rentapia everetti (Boulenger, 1896) (Everett’s Asian tree toad or marbled tree toad) of Sarawak / Borneo – around 1150m ASL

Rentapia everetti is a species of toad (family Bufonidae) endemic to Borneo. It is reported to occur in the north of the island, particularly in Sabah and Sarawak (Malaysia) and Brunei; its occurrence in neighbouring Kalimantan (Indonesia) is considered possible. Its altitudinal range is given as approximately 150–1250 m. The species was first described in 1896 by George Albert Boulenger; the type material comes from Mount Kinabalu (‘Mount Kina Balu’) in northern Borneo. In its taxonomic history, the species was described as Nectophryne everetti, among other names, and later placed in the genus Pedostibes before being classified in the genus Rentapia in the course of revisions of Asian ‘tree frog’ lineages. In the same revision, Rentapia rugosa (Pedostibes rugosus) is considered indistinguishable from R. everetti and is therefore treated as a synonym of R. everetti (priority principle).

The genus name Rentapia is an honour to Libau Rentap. The species epithet everetti is a patronym in honour of Alfred Hart Everett, who collected the type material. In terms of lifestyle, R. everetti is described as arboricolous (tree-dwelling) and associated with moist primary forests and well-preserved secondary forests in hilly lowlands up to submontane locations; small, slow-flowing, clear, stony streams are mentioned as the presumed reproductive habitat.
