Geographical distribution

Multiple localities around Boa Vista Island, Cabo Verde Archipelago.

Conservation status in IUCN Red List

Least concern.

Remarks

This species is widely distributed around the island of Boa Vista. Differences in color pattern have been invoked for the introduction of new names for certain local populations from the southeast and south coasts of the island without further justification. We hereby consider these names as synonyms. Thus, specimens matching the type material of Africonus wandae were studied in detail in Tenorio et al. (2014), and their haplotypes (cox1 gene fragment) showed to be identical with that of A. borgesi . The holotype of Africonus pedrofiadeiroi exhibits a white middle band patterned with minute brown zigzag markings, a feature characteristic of A. borgesi , which is considered conspecific.

Africonus borgesi and A. josephinae are very closely related according to the phylogeny. They belong to a lineage that contains species from Boa Vista and Maio islands, and is the sister group to the remaining Africonus .
