DiagnosisAdditional details, e.g. a detailed description or comparisons (2731 characters), are available for collaborators and contributors. Please contact us for details. 
CommentDistribution: Possibly in Bhutan (Lenz 2012). Not in Pakistan fide KHAN 2002 (pers. comm.). See map in Mohapatra et al. 2016: 116 (Fig. 1).

Habitat: partly arboreal (Harrington et al. 2018). 
EtymologyDaudin doesn’t seem to explain the etymology of this species. Beolens et al. believe that it may have been named after Helen of Troy, the classical embodiment of female beauty, in mind when he chose the binomial.

The name nigriangularis is composed by the Latin words nigri = “black,” and angularis = “angular,” that refers to the black V- or Y-shaped marking in the neck of this species.
