Kissing cousins: a review of the African genus Limnophis Günther, 1865 (Colubridae: Natricinae), with the description of a new species from north-eastern Angola
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Werner Conradie --- Port Elizabeth Museum (Bayworld), South Africa V Deepak --- Department of Life Sciences, The Natural History Museum, United Kingdom Chad Keates --- National Geographic Okavango Wilderness Project, South Africa David J Gower --- Department of Life Sciences, The Natural History Museum, United KingdomThe African natricine genus Limnophis is represented by two species: Limnophis bicolor Günther, 1865 and Limnophis bangweolicus (Mertens, 1936). They are stout-bodied, semi-aquatic snakes that mostly feed on fish and amphibians, and occur from Botswana and Namibia in the south... -
Current-day distribution of the rinkhals (Hemachatus haemachatus) in central South Africa and Lesotho: An evaluation based mainly on photographic and videographic records from social media
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Michael F Bates --- National Museum, South Africa Cora S Stobie --- National Museum, South AfricaThe rinkhals (Hemachatus haemachatus) is a well-known venomous elapid found in greater South Africa and the eastern highlands of Zimbabwe. To evaluate its current-day (mostly 2012–2021) distribution in central South Africa and Lesotho, we examined various media sources, including Facebook,... -
Digging adaptations evolved independently in two lineages of Psammophiid snake: evidence from cranial morphology
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Nick Sekits --- Whitman College, United States Walter Tunnell-Wilson --- Whitman College, United States Kate Jackson --- Whitman College, United StatesThe Beaked Snakes (Rhamphiophis) are semi-fossorial snakes with reinforced snouts adapted for digging. The Skaapstekers (Psammophylax) are generalist terrestrial snakes. Both belong to the family, Psammophiidae. The Striped Beaked Snake (Kladirostratus acutus) was originally assigned to the genus Rhamphiophis, because... -
A specimen of Leptotyphlops bicolor (Jan) from Ghana with a “subocular” (Serpentes: Leptotyphlopidae), with a note on the skull of this species
Item type: Journal Article • Journal: The Journal of the Herpetological Association of Africa • Authors: DonaldG. Broadley --- Research Associate, Natural History Museum of Zimbabwe,A specimen of Leptotyphlops bicolor (Jan) from Mole National Park, Ghana, has the second supralabial in broad contact with the third and it becomes a virtual subocular, excluding the ocular from the lip. This condition was previously considered diagnostic for... -
Patterned, plain, and in-between: An assessment of ecogeographic divergence between colour pattern morphs of the common egg-eater Dasypeltis scabra
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Jody M. Barends --- University of Johannesburg, South Africa Ielhaam Bassier --- University of the Western Cape, South Africa Emma E. Buckley --- University of the Western Cape, South Africa Cora S. Stobie --- National Museum, South Africa Michael F. Bates --- National Museum, South AfricaIntraspecific variation in colour patterns may reflect adaptive responses to local environmental regimes that favour selection of different trade-offs between visual communication, thermoregulation, and anti-predatory functions. Understanding the drivers of colour pattern variation within species can therefore provide valuable insights... -
Filling in the gaps: Distribution of the puff adder Bitis arietans (Merrem, 1820) in central South Africa and Lesotho – an investigation using mainly social media records and species distribution modelling
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Cora S Stobie --- National Museum, South Africa Michael F Bates --- National Museum, South AfricaThe puff adder (Bitis arietans) is widely distributed in Africa and south-western Arabia. Most published records for central South Africa and Lesotho are from surveys undertaken nearly 50 years ago, and although a large part of this area is considered...
