Crustacea Africa cryptic species fairy shrimp integrative taxonomy phylogeny


Three genera of Anostraca have been recorded so far in Senegal: Streptocephalus Baird, 1852, Branchinella Sayce, 1903 and Artemia Leach, 1819. The occurrence of the previously recorded freshwater species in Senegal have been confirmed in this work, namely Streptocephalus zeltneri Daday, 1910, S. sudanicus Daday, 1910 and Branchinella (Branchinellites) chudeaui (Daday, 1910). New records and the description of a new species are given. The new species, Streptocephalus wolof sp. nov., has been recognized through molecular (mitochondrial and nuclear markers) and morphological (egg shape) data. The adult stage of this new species is morphologically indistinguishable to its closely related species Streptocephalus zeltneri, suggesting the existence of two cryptic species in Senegal. Finally, some taxonomic comments on the genus Streptocephalus are presented.
