Abstract

A new species of Ptyctolaemus Peters, 1864 is described from Htamanthi Wildlife Sanctuary, Sagaing Division, Myanmar. The new species differs from P. gularis and Ptyctolaemus aff. gularis from Tibet, China, by having relatively longer limbs and different colorations of the gular region, and it differs from P. collicristatus by having much longer limbs and a less developed nuchal crest in males. Moreover, the new species differs genetically from Ptyctolaemus aff. gularis from Tibet, China, and P. collicristatus by an uncorrected percentage distance of 23.5% and 24.8%, respectively, inferred from mitochondrial NADH dehydrogenase subunit 2 gene sequences. This discovery increases the number of known Ptyctolaemus species to three.

Highlights

The agamid genus Ptyctolaemus Peters, 1864 is characterized by the males having longitudinal parallel folds on either side of the throat (Peters 1864; Ananjeva and Stuart 2001; Schulte et al 2004)

The specimens from Tibet, China, largely agree with the type specimen (Holotype ZMB 5004) of Ptyctolaemus gularis, there is a clear overlap in morphology of the

Summary

Introduction

The agamid genus Ptyctolaemus Peters, 1864 is characterized by the males having longitudinal parallel folds on either side of the throat (Peters 1864; Ananjeva and Stuart 2001; Schulte et al 2004). Ptyctolaemus currently contains two species: P. gularis (Peters, 1864) and P. collicristatus Schulte & Vindum, 2004. Mantheyus phuwuanensis (Manthey & Nabhitabhata, 1991), a species which once was assigned to Ptyctolaemus due to the presence of folds on either side of the throat (Manthey and Nabhitabhata 1991; Hallermann and Böhme 2003), is currently assigned to a monotypic genus (Ananjeva and Stuart 2001; Schulte et al 2004; Uetz et al 2021). Ptyctolaemus collicristatus is currently known only from Chin State, western Myanmar (Schulte et al 2004; Manthey 2010; Uetz et al 2021). In Myanmar, P. gularis was recorded from Kachin State (Smith 1940) and Sagaing Division (Schulte et al 2004)
