|Distribution||Australia (Queensland), New Guinea|
Type locality: Fort Du Bus and Oeroe-Langoeroe Bay (as W coast of New Guinea), Irian Jaya, Indonesia.
|Types||Holotype: RMNH 4812|
Syntypes: MSNG = MCG C. E. 28723, other syntypes not found fide COGGER 1983, from Wokam (as Wokan), Aru Ils., Indonesia [Monitor beccarii]
|Diagnosis||Diagnosis (Hapturosaurus): Hapturosaurus is a monophyletic (Ast 2001; Ziegler et al. 2007b) group of medium-sized (Collar et al. 2011), tree monitor lizards from New Guinea and northern Australia which is uniquely defined by the following combination of morphological characters: (1) A long and prehensile tail which is round in cross section together with (2) an elongated body, head, neck, limbs, and digits with strong claws in relation with a highly arboreal live style (Greene 1986; Mendyk & Horn 2011); (3) a partly colourful appearance of bright green, blue or yellow pigmentation in combination with a varying degree of black (including entirely melanistic taxa, such as beccarii and bogerti) often forming a dorsal pattern of more or less distinctive chevrons (Sprackland 1991; Jacobs 2008); (4) elongated dorsal scales separated by numerous rows of tiny granules and with a single distinctly enlarged posterior granulum; in addition, most body scales are roof-shaped and strongly keeled (this study, see Fig. 28); (5) differentiated head scales comprising enlarged supraocular scales and up to three rows of enlarged scales spanning the interorbital region (Koch et al. 2014); (6) lungs with an open intrapulmonary bronchus (Becker et al.1989); and (7) copulatory organs with bilaterally built hemipenial and hemiclitorial paryphasmata (Branch 1982; Böhme 1988; Ziegler & Böhme 1997). Furthermore, Conrad et al. (2011) listed five additional diagnostic morphological synapomorphies (next to 93 molecular synapomorphies; see Ast 2001) for the tree monitors. These are: (1) Palatine longer than wide; (2) parallel-sided (not expanded or tapered) anterior ends of the anterolateral processes of the frontal; (3) presence of a distinct, raised, posterior margin of the anterior narial fossa on the anterodorsal margin of the maxilla; (4) absence of a dorsal keel on the supraoccipital; and (5) crista interfenestralis developed posterolaterally and hides the occipital recess in lateral view (see also part two about the skull in Mertens’ [1942a] monograph).|
|Comment||Synonym partly after COGGER 1983 and MERTENS 1963. V. kordensis has been previously synonymzed with V. prasinus. However, JACOBS (2002) provides evidence that prasinus and kordensis are different species.|
Type species: Varanus prasinus is the type species of the subgenus Hapturosaurus Bucklitsch et al. 2016.
