The genus Protobothrops was described to accommodate two species previously placed in the genus Trimeresurus, T. jerdonii and T. mucrosquamatus. In their 2007 revision, Guo et al. placed 10 species in this genus, including P. mucrosquamatus.

The dangerously venomous Protobothrops mucrosquamatus is known from Myanmar (Kachin State), northeastern India and Bangladesh, China, Taiwan, and northern Vietnam. It is found n the Northern Triangle temperate and subtropical forests of Kachin State (Myanmar) at elevations of 250-1088 m. Individuals have been found near streams either under rocks or in the leaf litter. Historically, this species has been reported to be common in hilly and mountainous areas. More recently, the species has been described as common in Vietnam around villages and disturbed habitats. These snakes are active at night. (Leviton et al. 2003 and references therein)

Leviton et al. (2003) provide a technical description of this species: Scales in 25 longitudinal rows at midbody. Scales on upper surface of head small, each keeled posteriorly. Internasals 5-10 times size of adjacent scales, separated by 3-4 scales. Supraoculars long, narrow, undivided, 14-16 small interocular scales in line between them. 2 scales on line between upper preocular and nasal; 9-11 upper labials, first upper labial separated from nasal by suture; 2-3 small scales between upper labials and subocular; 2-3 rows of temporal scales above upper labials smooth, above those scales keeled; ventrals 200-218; subcaudals 76-91, all paired; grayish or olive brown above, with dorsal series of large brown, black-edged spots or blotches, and a lateral series of smaller spots; head above brownish, below whitish; belly whitish but heavily powdered with light brown; tail brownish (possibly pink in life) with series of dark dorsal spots. Hemipenes spinose. Total length: males: 1122 mm, females 1160 mm; tail length: males 195 mm, females 205 mm.

Guo and Zhao (2006) undertook an analysis of skull morphology of nine Asian pit vipers, including Protobothrops mucrosquamatus.

Zhang et al. (2013) sequenced the complete mitochondrial genome of P. mucrosquamatus.

Chen et al. (2007) discussed treatment in Taiwan of bites by P. mucrosquamatus and Trimeresurus stejnegeri, which together account for the majority of snakebites in northern Taiwan
