Abstract
Sampling of streams in the middle reaches of the Tana River Basin in Meru National Park, Kenya, from 2010 to 2012 for an NSF-funded International Research Experiences for Students (IRES) project, resulted in the capture of a number of specimens of what were first thought to be Neobola fluviatilis. On closer examination the specimens were determined to represent a distinct species, endemic to the Tana River basin, which is herein formally described. The new species is readily diagnosed from N. fluviatilis by higher counts of lateral line, pre-dorsal, and caudal peduncle circumferential scales, higher numbers of pectoral rays, lower numbers of anal fin rays, and a shorter anal-fin base length.
