| Distribution | New Guinea, Oceania (Ferguson Island, Trobriand Island) Type locality: Hall Sound, Central Province, 8°49’S 146°36’E, Papua New Guinea. Type locality: “costa della Nuova Guinea che sta in prossomità dell’Isola Yule” [= Central Province, Papua New Guinea] [G. (L.) albertisii PETERS & DORIA 1878]. |
| Reproduction | oviparous |
| Types | Holotype: AMS R 31883 (formerly MAMU R335, MR833) Holotype: ZMB 21387, adult male, paratypes adult females ZMB 16371 and 16372, all leg. Prof. Dr. Neuhauss; Sattelberg, Kaiser–Wilhelmsland [longicauda] Syntypes: ZMB 9722, ZMB 9724-25, MSNG 29122, NMW [albertisii] |
| Diagnosis | Diagnosis (papuensis): Large, robust, long–tailed species with homogeneous dorsal scalation and a discontinuous vertebral crest. An area of strongly enlarged scales below the tympanum, a row of enlarged submaxillaries present; anterior edge of the gular pouch without enlarged scales. Males with a high tail at base. Similar to H. binotatus (with the exception of the basal part of the tail in males). H. papuensis differs from binotatus by a vertebral crest indented near the nape (vs. continuous), larger tympani T/E > 1.0 (vs. ≤ 1.0) as well as a strongly raised tail at the base present in males (vs. not raised); auritus, geelvinkianus, modestus, nigrigularis and bruijnii by the presence of strongly enlarged scales below the tympanum (vs. absent); all other species by the presence of a dark, above and behind brighter limited spot on either side of the neck (vs. absent); additionally from schultzewestrumi by smaller gulars, ≈ Ø tympanum (vs. some = ≥ Ø tympanum) and from boydii, spinipes and dilophus by a homogeneous dorsal scalation (vs. heterogeneous) and a longer tail TL/SVL > 2.9 (vs. < 2.3) (Manthey & Denzer 2006: 19). Diagnosis (longicauda): Large, robust, long-tailed and long-legged species (SVL of males up to 205, females up to 190 mm; TL/SVL usually > 3.6) with homogeneous dorsal scalation and a discontinuous vertebral crest. Strongly enlarged scales below the tympanum; a row of enlarged submaxillaries present; anterior edge of the gular pouch without enlarged scales. The subspecies longicauda differs from the nominate form by an only moderately raised tail at its base in adult males (height of tail/width of tail < 1.7), decreasing in height slowly behind the first third of the tail [vs. strongly raised (height of tail/width of tail ≥ 1.97), decreasing abruptly], a longer tail TL/SVL > 3.6 (vs. ≤ 3.4) as well as longer legs HBL + FL > 0.831 (vs. < 0.81) and feet FL/SVL > 0.37 (vs. < 0.36) (Manthey & Denzer 2006: 21). |
