| Listrura costai, new species, is described from small streams in a swampy coastal plain in the rio Jurumirim basin, Angra dos Reis Municipality, Rio de Janeiro State, southeastern Brazil. The new species is morphologically very similar to L. nematopteryx and L. picinguabae, all possessing only one long pectoral-fin ray. It differs from its congeners by possessing an autapomorphic character: first hypobranchial with an anterior process (vs. process absent). Other features such as coloration, numbers of opercular and interopercular odontodes, number of anal-fin rays, head length, and shape of some bone structures help to distinguish the new species from L. nematopteryx and L. picinguabae. Molecular analyses using partial sequences of the mitochondrial DNA... |

| The genus Listrura, Glanapteryginae, currently comprises six valid species of small and elongated trichomycterid catfishes that inhabit coastal plains of Southern and Southeastern Brazil. As primarily fossorial dwellers, species of the genus display unusual morphological adaptations and restricted habitats, which make these fishes particularly susceptible to environmental disturbance. Listrura camposi is poorly known and ranked as a Critically Endangered catfish species, according to current Brazilian list of threatened species. Description of the species was based on a single specimen collected in 1940, and for seven decades no additional specimens were reported. As a consequence, basic information about the species is unavailable. Recently, a population... |
