SynonymSinomicrurus peinani LIU, YAN, HOU, WANG, NGUYEN, MURPHY, CHE & GUO 2020 
DistributionChina (Guangxi), Vietnam (Cao Bằng and Vinh Phuc)

Type locality: Cangwu County (N23.65°, E111.56°), Guangxi, China, elevation of ~30 m  
TypesHolotype: YBU 16086, adult female; collected on 05 June 2016.
Paratypes (three specimens): YBU 16054, female; YBU 16066, male; YBU 16067, female. Same locality and date as holotype. 
DiagnosisDiagnosis: All examined specimens possessed a small to medium-sized body, varying from 368 mm to 620 mm, as well as: (1) 30–35 black cross-bands on body and tail; (2) 13 dorsal scale rows throughout, all smooth; (3) white belly with black speckles or bands; (4) broad white transverse bar on top of head with inverted V-shaped anterior margin, white bar wider than anterior black bar; and (5) frontal V-like, 1.3 times as long as wide.

Comparisons: Sinomicrurus peinani sp. nov. differs from S. m. univirgatus by its different body pattern, with the latter having black vertebral strip and transverse bars restricted to sides of body, or absent altogether (Günther, 1868). Sinomicrurus peinani sp. nov. can be distinguished from the other three subspecies by broad white transverse band with inverted V-shaped anterior margin on top of head (vs. two white bands with straight margin) and V-shaped frontal (vs. spindle-shaped frontal), small and not closely arranged cross-bands and spots (Figure 1D) (vs. more closely arranged black cross-bands and spots on belly, such that abdomen appears dark black, Figure 1E) (Reinhardt, 1844; Maki, 1935; van Denburgh, 1912; Zhao, 2006). Sinomicrurus peinani sp. nov. can be distinguished from S. macclellandi by white band on top of head wider than anterior black band vs. white band generally as wide as anterior black band. Historically, several other names have been allied to S. macclellandi, e.g., Calliophis macclellandi gorei Wall, 1910 and Calliophis macclellandi concolor Wall, 1925, with the first described from India and the latter described from Myanmar. Nevertheless, the new species differs from both by having black transverse bars on body (vs. without) (Wall, 1910, 1925). 
EtymologyThe species is named after Professor Pei-Nan Yu, a distinguished doctor in China, in recognition of his great contribution to the treatment of snakebite.
