= Hypsilurus megapogon (Duméril & Bibron, 1837)
Syntypes: RMNH. RENA.3048, male, Lobo, New Guinea, coll. Müller 1828; RMNH. RENA.3049, male, same locality assumed, coll. Müller & Macklot 1828.
Type locality: “im hohen Wald“ [in the high (primary) forest]) near Lobo, Triton Bay, New Guinea
Remarks: The type status and nomenclature of the Naturalis specimens of Calotes megapogon are discussed in detail in Denzer & Dondorp (2023b). Briefly, the name Calotes megapogon was published as a synonym of Lophyrus dilophus (comb. nov. pro Tiaris dilophus Duméril & Bibron, 1836) by Duméril & Bibron (1837). In a later publication by Gray (1845) made the name megapogon available for nomenclatural purposes in accordance with Art. 11.6.1 of the Code (IZCN 1999) in the new combination Tiaris megapogon. Comparison of the Naturalis specimens with the holotype by monotypy of Tiaris dilophus Duméril & Bibron, 1836 revealed that they belong to different genera (Denzer & Dondorp 2023b). Tiaris dilophus belongs to the genus Lophosaurus Fitzinger, current name Lophosaurus dilophus (Duméril & Bibron, 1836), while Calotes megapogon is a member of the genus Hypsilurus Peters related to the species Hypsilurus auritus (Meyer, 1874) and Hypsilurus spinosus (Duméril & Duméril, 1851). The latter two species were shown to be conspecific and synonymized with Hypsilurus megapogon which constitutes the oldest available and therefore the applicable name for the taxon.
