A new and threatened species of Listrura (Siluriformes: Trichomycteridae), a rare catfish from an Atlantic Forest continental island

This dataset contains the digitized treatments in Plazi based on the original journal article de Medeiros, Lucas Silva, Donin, Laura Modesti, Ferrer, Juliano, Lima, Sergio Maia Queiroz, de Pinna, Mário (2024): A new and threatened species of Listrura (Siluriformes: Trichomycteridae), a rare catfish from an Atlantic Forest continental island. Neotropical Ichthyology 22 (3): e 230136, DOI: 10.1590/1982-0224-2023-0136, URL: doi.org/10.1590/1982-0224-2023-0136 Listrura is a genus of small pencil catfishes of Trichomycteridae that currently comprises 12 valid species in coastal drainages of Southern and Southeastern Brazil, all with fossorial dwelling habitats and eel-like morphology.

Here, we describe a new species of Listrura known from only two specimens collected in an interval of 24 years in order to make it taxonomically available for biodiversity inventories and conservation decisions. The new species is morphologically distinguished from its congeners by the combination of features, as pectoral-fin rays counts, number of free vertebrae, number caudal-fin procurrent rays, interopercular odontodes counts and the anterior-most position of dorsal and anal fin.
