DiagnosisDiagnosis: Mastigodryas moratoi differs from all other species in the genus by the combined presence of five distinct dark dorsal stripes on the anterior portion of the body (one mediodorsal, two dorsolaterals, and two laterals); gular region smudged with dark or mostly dark with cream spots until the level of the first ventrals; tail uniformly reddish or yellowish; usually eight supralabials, with the third, fourth, and fifth in contact with the orbit; midregion of the hemipenis below the capitulum with several enlarged spines, one of which is significantly larger and hooklike. 
CommentHabitat: partly arboreal (Harrington et al. 2018).
