Caridina H. Milne Edwards, 1837 (Crustacea: Decapoda: Caridea: Atyoidea: Atyidae) - freshwater shrimps from eastern and southern Africa

Since the study of Richard and Clark (2009), additional material of Caridina africana Kingsley, 1882 has been examined and as a consequence C. nilotica var. paucipara Weber, 1897 is considered to be a junior synonym of C. africana. Material of Caridina serratirostris De Man, 1892, C. angulata Bouvier, 1905, C. brachydactyla De Man, 1908 and C. moeri Woltereck, 1984 is reported, and redescribed. Caridina serratirostris and C. angulata are reported for the first time from the African mainland, both species being previously known from Madagascar. The first record of C. brachydactyla from the African continent is also noted. Furthermore, Caridina nilotica var. natalensis De Man, 1908 and Caridina nilotica var. brevidactyla J. Roux, 1920 are considered to be junior synonyms of C. brachydactyla. Part of the type series of C. brachydactyla was examined for the present study and this material together with the description and figures of the rostrum illustrated by De Man (1892) as Caridina wyckii appear to be three different species: C. brachydactyla s. str. and probably two new species. These are not described due to lack of additional material available for study. However, two new African species are described and an identification key is provided.
