Megophrys (Panophrys) hoanglienensis Figs. 3D and 7 Molecular data: A 16S sequence was generated from tissue samples collected from one tadpole (VNMN010903) and uncorrected p -distance between this sequence and that of the holotype of M. hoanglienensis also collected on Mount Fansipan, Sa Pa District, Lao Cai Province, Vietnam (Genbank accession number MH 514889) was 0.0 %. Collection site: The following tadpole description is based on a single specimen (VNMN010903) at Stage 26. The specimen was found feeding in a 5 m wide stream in disturbed evergreen forest on Mount Fansipan, Hoang Lien National Park, Tam Duong District, Lai Chau Province, Vietnam (22.3483°N 103.7700°E, 1901 m asl; Figs. 1 and 2B), on 10 September 2018 by Luan Nguyen, Chung Nguyen and Luong Hoang. Morphology: The body is longitudinally oval shaped and dorsally compressed; the nares are oval and are closer to the eyes than to the snout, the rims of the nares are serrated and raised from the body wall, the internarial distance is less than the interorbital distance; the eyes are positioned dorsolaterally, the pupils are round; the spiracle is sinistral and the spiracular tube protrudes from midway along the body wall and anterior to maximal trunk width and opens laterally; the tail length is 73.2% of the total length; the dorsal tail fin inserts behind the body-tail junction, the dorsal fin is low, particularly towards the anterior half of the tail length; the basal tail width is 43.5%, of the maximal trunk width, the tail tip is pointed; the oral disc is subterminal and antero-dorsal; the lateral corners fold medially and turn upward when not fully extended (and in preservative), the mean width of the umbelliform oral disc makes up 47.8% of the maximal width of the trunk, in life the width of the umbelliform oral disc exceeds the maximal width of the trunk; in life the maximal BW is 79.3% (n =1) the maximal width of the fully extended ODW; the lower lip is bi-triangular shaped; marginal papillae are absent, the edges of the lips are smooth; ...
