Costa, W.J.E.M. 2019. Two new species of seasonal killifishes of the Nothobranchius melanospilus species Complex from the East Africa Biodiversity Hotspot (Cyprinodontiformes: Aplocheilidae). Vertebrate Zoology, 69 (1): 75, fig. 1. 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.
