Crocker Range National Park in Sabah (East Malaysia), northern Borneo, is an exceptional area for herpetological diversity. Inventories of the Park are incomplete, but show high diversity, as well as regional endemicity shared with the adjacent and more well-known Gunung Kinabalu National Park. The montane ecosystem of the Range offers refuge for a number of rare herpetofaunal taxa, including Stoliczkia borneensis, Rhabdophis murudensis, Oligodon everetti, Philautus bunitus, Ansonia anotis, Sphenomorphus aesculeticola, and undescribed species of squamates of the genera Sphenomorphus and Gongylosoma. The 59 species of amphibians and 45 species of reptiles now recorded from the Range represent 39 and 16.2 per cent of the total Bornean amphibian and reptile fauna, respectively. The high levels of deforestation of the surrounding regions of Borneo, particularly lowland rainforests, highten the importance of protection of primary forests of northern Borneo’s Crocker Range.
The taxonomy of king cobras (Ophiophagus) was reevaluated using qualitative, mensural and meristic characters, based on 148 entire and five skeletal specimens, and supported by a recent molecular phylogenetic analysis. We provide nomenclatural synopses of both the genus and species-series nomina. We restrict the concept of Ophiophagus hannah s. str. to populations from eastern Pakistan, northern and eastern India, the Andaman Islands, Indo-Burma and Indo-China, south to central Thailand. The nomen Ophiophagus bungarus (Schlegel, 1837) comb. nov. is revived for the populations inhabiting the Sunda Shelf area, including the Malay Peninsula, the Greater Sunda Islands and parts of the southern Philippines. We describe two new species, Ophiophagus kaalinga Gowri Shankar, Das & Ganesh sp. nov. endemic to the Western Ghats of south-western India and Ophiophagus salvatana Gowri Shankar, Das & Wüster sp. nov., inhabiting the island of Luzon in northern Philippines. For the purpose of nomenclatural stability, we designate a neotype for Hamadryas hannah Cantor, 1836. A dichotomous identification key to the four species recognized here is provided.
