Megophrys (Panophrys) jingdongensis Fei and Ye

Megophrys (Panophrys) jingdongensis Figs. 3C and 6 Molecular data: A 16S sequence was generated from a tissue sample obtained from the single tadpole (VNMN010902). Uncorrected p -distance between the tadpole in this study and a M. jingdongensis specimen collected approximately 390 km to the northwest in the proximity of the type locality; Wenlong, Jingdong County, Yunnan Province, China (GenBank accession number KX 811874) was 0.1 %. Collection site: The following tadpole description is based on a single specimen (VNMN010902) at Stage 25. The specimen was found near the bank in a large, 2 m wide pool in heavily disturbed evergreen forest on Mount Pu Ta Leng, Bat Xat Nature Reserve, Bat Xat District, Lao Cai Province, Vietnam (22.4322°N 103.6297°E, 1912 m asl; Figs. 1 and 2A), at 15:00 h on 20 March 2018 by Luan Nguyen, Christopher Portway, Chung Nguyen and Benjamin Tapley. Morphology: The body is elongated and slender; 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 68.1% of the total length; the dorsal tail fin inserts behind the body-tail junction, the dorsal fin is low, particularly towards the proximal half of the tail length; the basal tail width is 48.8% of the maximal trunk width, the tail tip is rounded; the oral disc is subterminal and antero-dorsal; the lateral corners fold medially and turn upward when not fully extended (and in preservative), the width of the umbelliform oral disc makes up 63.4% of the maximal width of the trunk; in life the maximal BW is 80.4% (n =1) the maximal width of the fully extended ODW; the lower lip is bi-triangular shaped; marginal papillae are absent; regularly positioned, round and oblong shaped ...
