The river sardine,    Mesobola   brevianalis    (Boulenger, 1908), is the type species of    Mesobola    Howes, 1984. Standard phylogenetic analyses of partial sequences of the cytochrome oxidase I gene of individuals from populations across southern Africa that are currently identified as    M.   brevianalis    showed that these populations represent four genetically distinct allopatric lineages. Furthermore,    Engraulicypris   sardella    (Günther, 1868), the type species of    Engraulicypris    Günther, 1894, was convincingly nested amongst these clades. These findings support synonymisation of    Engraulicypris    and    Mesobola    syn. n. ; restoration of    Engraulicypris   gariepinus    (Barnard, 1943),  stat. rev.  for the lower Orange River population; description of two new species,    Engraulicypris   ngalala    sp. n.  and    Engraulicypris   howesi    sp. n.  from the Rovuma and Kunene river systems, respectively; affirmation of the synonymy of    Engraulicypris   brevianalis    (Boulenger, 1908),  comb. n.  sensu stricto and    Engraulicypris   whitei    van der Horst, 1934; and restoration of    Engraulicypris   bredoi    Poll, 1945,  stat. rev.  and    Engraulicypris   spinifer    Bailey &amp; Matthes, 1971,  stat. rev.  from    Mesobola   . Discriminant function analysis of a truss network of five traditional morphometric measurements and 21 morphometric measurements that characterised the shape of the fishes was used to seek morphological markers for the genetically distinct populations. Only    E.   gariepinus    was morphometrically distinctive, but live colouration differed between the lineages. Detailed taxonomic descriptions and an identification key for the species are provided.
