| Diagnosis | Diagnosis: A large species of Gonocephalus reaching 424 mm in length (SVL = 147 mm (NOT 277 mm as given in the original diagnosis) and distinguished from all congeners by the following combination of characters: (1) nuchal and dorsal crests separated by pectoral gap spanning 3–13 scales; (2) gulars crest of 9–12 projecting triangular scales, total gular scales 36–49 from mental or chinshields to point where gular pouch attaches to chest; (3) rostral single, 2.6–3.6 times as wide as tall; (4) usually two large tubercular scales ventral to tympanum, separated from one another by small scales; (5) scales on lower flanks heterogenous, large scales or small patches of large scales separated from one another by much smaller scales; (6) scales around midbody 97–125; (7) keeling very reduced over much of body, gulars and ventrals smooth or feebly arched; (8) in life, mostly green with banded limbs and tail and with large scales on flanks paler than intervening scales (capable of considerable color change to varying shades of brown and degree of banding); (9) eye surrounded by distinctive ring of pale scales or palpebrals almost entirely cream or pale yellow; (10) iris brown in young individuals, blue in large adults. |

| Etymology | The new name pyrius is a masculine adjective derived from the Greek word pyrios (ptqio1), meaning fire. In addition to having an evolutionary origin likely influenced by the fiery volcanic history of Sumatra, gravid female Gonocephalus pyrius develop a fiery countenance when threatened as their usual green coloration changes to black with fiery yellow, orange, and crimson markings. |
