dc.description.abstract |
The herpetofauna of Angola has been neglected for many years, but recent surveys have revealed
previously unknown diversity and a consequent increase in the number of species recorded for the country. Most
historical surveys focused on the north-eastern and south-western parts of the country, while mostly neglecting
the central and south-eastern parts, comprising the provinces of Bié, Moxico, and Cuando Cubango. To address
this sampling bias and investigate the conservation importance of the region, a series of rapid biodiversity
surveys of the upper Cuito, Cubango, Cuando, Zambezi, and Cuanza river basins were conducted by the National
Geographic Okavango Wilderness Project between 2015 and 2019. The first part of those survey results are
presented here as an updated checklist of current and historical snake records from the south-eastern region
of Angola. In summary, 160 new specimens were collected from the region, comprising 36 species, bringing the
total number of recognized snake species for the region to 53. These surveys revealed three new country records
(Amblyodipsas ventrimaculata, Crotaphopeltis barotseensis, and Dasypeltis confusa) and led to the description
of two novel species in previous publications (Boaedon branchi and B. fradei), increasing the total number
of snake species in Angola to 133. Finally, updated geographic distribution maps are provided for all species
encountered in this study for the whole country. This contribution increases our knowledge of this poorly known
region of Africa and highlights the need for and importance of similar studies in other undersampled areas. |

A herpetofauna de Angola foi negligenciada durante muitos anos. A maior parte dos levantamentos
realizados a nível histórico incidiram no nordeste e sudoeste do país, sendo o centro e o sudeste, englobando
as províncias do Bié, Moxico e Cuando Cubango, menos estudado. Para resolver este enviesamento de
amostragem, foram realizados uma série de levantamentos rápidos de biodiversidade das nascentes do alto
Cuito, Cubango, Okavango, Cuando, Zambeze e Cuanza pelo National Geographic Okavango Wilderness Project
entre 2015 e 2019. Aqui apresentamos a primeira parte dos nossos resultados, uma lista actualizada de registos
novos e históricos de cobras do sudeste de Angola. 160 novos registros de espécimes foram documentados
na região, incluindo 36 espécies, e elevando o número total de espécies reconhecidas da região para 53. Estes
levantamentos revelaram três novos registos para Angola (Amblyodipsas ventrimaculata, Crotaphopeltis
barotseensis, e Dasypeltis confusa) e levaram à descrição de duas novas espécies (Boaedon branchi e B.
fradei), aumentando o número de espécies do país para 133. Por fim, produzimos mapas de distribuição
atualizados de todas as espécies encontradas neste estudo para todo o território de Angola. Este estudo é
uma contribuição significativa para o conhecimento desta região pouco estudada do continente africano, e
destaca a necessidade e importância de estudos semelhantes em áreas subamostradas. |
