Another new Cophixalus species (Amphibia: Anura: Microhylidae) from western New Guinea

摘要

Based on external morphological, anatomical, bioacoustic, and molecular traits, a new species in the micro-hylid genus Cophixalus is described. The new species was discovered in the Fakfak Mountains, northwestern corner of the Bomberai Peninsula, Papua Province, Indonesia. The new taxon is most closely related to the sympatic Cophixalus tetzlaffi. It differs from that species in several morphological traits, but primarily by its advertisement call: the new species utters a single peeping note with amean duration of less than 200 milliseconds, whereas the advertisement call of C. tetzlaffi consists of three to four notes, with a mean note duration of more than 400 milliseconds. Molecular data (mitochondrial 16S rRNA) support the determination of thespecific distinctness of the new species.
