articleOpen accessABSTRACT Here we describe a new hypopomid species, Microsternarchus javieri n. sp., encountered in flooded savanna streams of the Branco River and in terra-firme streams in the mid- and lower portions of the Negro River basin. We compared this new species with M. bilineatus from the San Bartolo River, Venezuela, and M. brevis from the upper portion of the Negro River. We also compared this new species with two recently described species in the genus Microsternarchus, M. longicaudatus and M. schonmanni. We examined morphometrics, anatomical characters, DNA barcode distances for the COI (cytochrome C oxidase subunit I) gene, and electric organ discharge (EOD) parameters. We diagnosed M. javieri n.sp. based on variation in maximum body depth, eye diameter, caudal vertebral counts, number of anal fin rays, and the shape of the maxillae. The average intra-specific genetic distance (K2P) in M. javieri n.sp. was 0.83%, whereas the average inter-specific genetic distance to M. brevis was 12.45%, and to other hypopomids ranged from 17.21 to 21.54%. When comparing EOD waveforms of the new species with M. brevis, we found differences in repetition rate, the ratio between the first and second phase areas, and the polarity balance. The description of M. javieri n. sp. increases to five the number of species in the genus.

Uma nova espécie, Microsternarchus schonmanni, é descrita a partir de uma série de especimens coletados nas drenagens da parte baixa do Rio Pacaás Novas e Rio Mamoré-Guaporé, Brasil. Essa é uma região de elevada biodiversidade, com florestas periodicamente inundadas e savanas. A espécie nova é diagnosticada a partir das espécies nominais M. bilineatus, M. brevis e M. longicaudatus por medidas que incluem o comprimento do filamento caudal, o tamanho da boca e dos olhos, e a distância do focinho à narina posterior. Além disso, a nova espécie difere das demais pelo número mais elevado de raios da nadadeira anal. Ademais, o maxilar mais amplo de M. schonmanni difere do maxilar mais alongado de M. bilineatus, M. brevis e M. longicaudatus.
