---|---|---|
M. Ivanov et al. 2018 | Mid-sized Varanus with estimated snout-vent length up to about 38 cm; differs from all other species in the genus on the basis of a single autapomorphy – parietal and squamosal processes of postorbitofrontal forming a
distinctly acute angle – and the following combination of features: (1) short septomaxilla with flat dorsal surface; (2) frontal and anterolateral postorbital processes of post- orbitofrontal forming obtuse angle; (3) posterior margin of nasal lobe of frontal situated in middle of dorsal width of rostral process; (4) posterior margin of anteroposter- iorly elongated frontal relatively narrow; (5) parietal with wide subrectangular fronto-postfrontal processes, anteri- orly arched fronto-parietal suture, and parietal foramen situated significantly posterior to anterior margin of bone (more than one-third of parietal plate length); (6) distance between medially converging parietal crests of parietal shortest in posterior quarter of parietal plate length; (7) otoccipital with very distinct occipital crest at base of paroccipital process; (8) pointed conical teeth with dis- tally recurved apices and prominent smooth mesial and distal cutting edges; (9) trunk vertebrae with moderately developed depression between pars tectiformis and medial margin of prezygapophyses and with posterolaterally directed postzygapophyses forming a right angle; (10) preacetabular process of ilium prominent and directed at right angle to pubic process; and (11) bifurcated iliac crest prominent. |
