Abstract
 We report on biological notes of an enigmatic asterophryine Gastrophrynoides borneensis based on a male collected from western Sarawak. The male is immaculate brown in dorsal colour, without small white spots contrasting to previous descriptions. Whether this indicates intraspecific variation or specific differentiation requires further study. Mitochondrial DNA analysis revealed the species to be monophyletic with, but sufficiently diversified from, the continental G . i mmaculatus. The species emits two call types that are distinct from calls reported in Asterophryinae. 

Key words: acoustics, Asterophryinae, body color, Gastrophrynoides immaculatus, mitochondrial phylogeny
