| 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). 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 gu¬lar 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). |
