|Types||Holotype: PNM 9719 (formerly KU 320000; LJW ﬁeld number 071), adult male, salvaged from hunter, 29 June 2009. Paratypes: KU 322188 (ACD|
|Diagnosis||Diagnosis: Varanus bitatawa differs from congeners by the combination of (i) large, robust body (and related scalation differences: table 1), (ii) contrasting black and golden yellow dorsal coloration, (iii) dark gular coloration in juveniles, (iv) anteriorly directed, slit-like external nares, and (v) multiple characters of hemipeneal morphology (ﬁgure 2; electronic supplementary material). Additionally, the new species is distinguished from congeners by marked divergence in mitochondrial and nuclear gene sequences and differs from its closest relative, V. olivaceus, by genetic divergence in excess of the divergence between other Asian species (ﬁgure 1 and table 2; electronic supplementary material, ﬁgure S2 and table S3). Detailed comparisons are provided in the electronic supplementar y material [from WELTON et al. 2010].|
