Gracixalus quyeti (Nguyen, Hendrix, Böhme, Vu, and Ziegler, 2008)

Quyet’s Bushfrog ( Fig. 5D )

Two individuals of G. quyeti were observed by P. Brakels and N. Maury on 15 November 2018 in Khounkham District site 2, Khammouan Province (17°57.160’N, 104°43.793’E; elevation 500 m asl) .

Morphological characters of the individuals from Khammouan Province agreed well with the description of Egert et al. (2017). The photographed individual ( Fig. 5D ) agrees with the diagnosis of G. quyeti in the following characters: small body size; snout rounded; canthus rostralis distinct, loreal region slightly concave; tympanum distinct, supratympanic fold present; tips of fingers and toes enlarged into round discs; tibiotarsal projection absent; dorsal surface with small sharp tubercles; coloration of dorsum gray with brown marbling; ventral surface of throat, chest and belly yellowish.

Ecological notes. The individual was found at ca. 2100 h hiding in rock crevices a few meters inside a limestone cave. The surrounding habitat was dry mixed evergreen forest on limestone within close proximity of riverine forest.

Distribution. In Laos, this species has been previously recorded from Hin Nam No NPA, Boualapha District, Khammouan Province, near the Vietnam border ( Egert et al. 2017). This is the first record from Khounkham District, Khammouan Province, which represents a range extension of ca. 150 km to the northwest. Elsewhere, this species has been reported from central Vietnam ( Frost 2020).
