PSEUDOCALOTES FITZINGER, 1843 View in CoL

Type species: Pseudocalotes tympanistriga (Gray, 1831) .

Diagnosis: Pseudocalotes can be diagnosed from other Draconinae genera by having: (1) scales of lateral head smooth, especially loreal and subocular region; (2) scales of lateral jaw enlarged; (3) scales of central gular region distinctively smaller than others of throat; (4) sub-orbital scale row usually one, or multiple but with the middle one significantly enlarged; (5) post-orbital and post-occipital spines absent; (6) nuchal crest scales mostly elongated and tall, CL/HL mostly>10%; (7) dorsal crest scales feeble and low; (8) dorsal body scales heterogeneous in size and shape; (9) enlarged dorsal body scales not arranged in paravertebral, dorsolateral or V-shaped ridges.

Phylogenetic definition: We define Pseudocalotes using the maximum crown-clade definition, which includes species that share a more recent common ancestor with Pseudocalotes tympanistriga than with Diploderma polygonatum and Acanthosaura lepidogaster .

Included species: A single species of Japalura s.l. Pseudocalotes kingdonwardi bapoensis , is reclassified into the genus Pseudocalotes . Currently, the genus includes 22 recognized species in total ( Grismer et al., 2016a; Harvey et al., 2017).

Geographic distribution: The genus is distributed in South-East Asia and Indochina, including southern Mainland China, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Sumatra, Thailand and Vietnam ( Fig. 5).
