A New Species of the Natricine Snake Genus Amphiesma from Borneo (Squamata: Natricidae)

Patrick David, Gernot Vogel

Abstract


A new species of the natricine snake genus Amphiesma is described from a single specimen obtained from Borneo by Franz Steindachner in 1878. Amphiesma arquus sp. nov. is distinguished from other species of the Sunda Region by the combination of an elongated body, 17 + 3 enlarged maxillary teeth, 17 – 17 – 15 dorsal scale rows, all strongly keeled, absence of a loreal, a high number of ventrals and subcaudals, supralabials ornate with white arched markings, and an obscured venter. Its generic position, especially in respect with the genus Tropidonophis Jan, 1863, is discussed. This new species is compared with other Asian natricine species with 17 dorsal scale rows. A key to natricine species known from Borneo is provided.
