Megophrys (Xenophrys) maosonensis Figs. 3E and 8 Molecular data: A 16S sequence was generated from a tissue sample obtained from the single tadpole (VNMN010904). Uncorrected p -distance between the tadpole in this study and a M. maosonensis specimen also collected in the rough proximity of one of the type specimens; Sa Pa District, Lao Cai Province, Vietnam (GenBank accession number KX 811786) was 0.0 %. Collection site: The following tadpole description is based on two specimens at Gosner stage 25 (VNMN010904 and HLNP 2018090900015). The specimens were found feeding in a 8 m wide stream in disturbed evergreen forest on Mount Fansipan, Hoang Lien National Park, Cat Cat river, Sa Pa District, Lao Cai Province, Vietnam (22.3214°N 103.8264°E, 1244 m asl; Figs. 1 and 2D), on 9 September 2018 by Luan Nguyen, Chung Nguyen and Luong Hoang. Morphology: The body is elongated and slender; the nares are oval and are approximately equal in distance from the eyes and 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 one third of the way along the body, anterior to maximal trunk width and opens laterally; the tail length is 76.5–77.9% 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 51.2–61.0%, of the maximal trunk width; the tail tip is narrowly 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 mean width of the umbelliform oral disc makes up 63.4–68.3% of the maximal width of the trunk; in life, the maximal BW is 73.2% (n =1)the maximal width of the fully extended ODW and the width of the umbelliform oral disc exceeds the maximal width of the trunk; the lower lip is ...
