[[ Genus Myoglanis ]]

Myoglanis is distinguished from its closest relatives Leptorhamdia and Brachyglanis by its apomorphically high numbers of caudal vertebrae and anal-fin rays, and thickened basal half of the adipose fin that is confluent with the caudal fin. Myoglanis currently comprises two species, the type species M. potaroensis Eigenmann , from the Essequibo River basin of Guyana, and M. koepckei Chang , from a tributary of the Río Nanay in the Peruvian Amazon basin. We recognize, nevertheless, that additional systematic work is needed on Myoglanis , Leptorhamdia and Brachyglanis plus Gladioglanis and Phreatobius to document character variation among the described and known yet undescribed species, to test monophyly of the genera and to clarify their interrelationships.
