A new species of green-eyed Cordylus Laurenti, 1768 from the west-central highlands of Angola, and the rediscovery of Cordylus angolensis (Bocage, 1895) (Squamata: Cordylidae)

description | Cordylus angolensis (Bocage, 1895) was described 128 years ago on the basis of a single specimen collected at Caconda in the west-central highlands of Angola. Additional specimens referred to this species were collected at ‘Mombolo’ (also in the central highlands) during the Vernay Angola Expedition in 1925. As the holotype was apparently destroyed in the fire of 1978 at the Museu Bocage in Lisbon and no additional specimens have been collected, its taxonomic status and phylogenetic relationships has remained uncertain. The species has eluded all efforts aimed at its re-discovery in the vicinity of the type locality, with a single specimen from near Condé, north of Mombolo—collected in 1970 by Wulf Haacke—the only other specimen of Cordylus known from west-central Angola. Recent field work in the Angolan highlands resulted in the collection of a series of specimens from Taqueta Mountain (west of Caconda), Monte Verde (Sandula, ‘Mombolo’) and Uassamba (Vondo). A phylogenetic analysis, using three mitochondrial and six nuclear genes, indicated the existence of two distinct species-level lineages in the Angolan highlands. These two species are allopatric and morphologically distinct, differing especially in terms of their colour patterns, eye colour and certain scalation characteristics. We therefore confirm that C. angolensis is a valid species and designate a neotype, and describe a new species, Cordylus momboloensis sp. nov. |
