Nothobranchius melanospilus species Complex from the East

Abstract
During a revision of material identified in museum collections as
Nothobranchius melanospilus, two new species were recognised: N.
kwalensis, new species, from the Ramisi River basin, southeastem Kenya,
and N. prognathus, new species, from the upper Wami River basin,
eastem Tanzania. Both new species are distinguished from N.
melanospilus by Ilse relative position of the dorsal-fin origin in females,
presence of dark dots an the whole flank in females, the two sections of
the anterior supraorbital series of neuromasts well-separated, and
presence of fewer mandibular neuromasts. Nothobranchius prognathus is
distinguished from other species of the N. melanospilus complex by the
shape of the snout and eye, frontal squamation, and basal portion of the
pelvic fins medially united in males. Additional moephometric characters
were found informative to diagnose species of the N. melanospilus
complex.
