Abstract

CONDE-VELA, Víctor Manuel. Redescriptions of four nereidid species (Annelida: Phyllodocida: Nereididae) from the Atlantic Ocean described by Aaron Louis Treadwell. Rev. Mex. Biodiv. [online]. 2022, vol.93, e934052.  Epub Dec 12, 2022. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2022.93.4052.

Aaron Louis Treadwell proposed a large number of new taxa, and several of them are regarded as synonyms. Treadwell proposed 32 new species in the family Nereididae, and a few of them have been re-evaluated. Here, the validity of 4 species is reassessed based on the examination of type material of 3 Nereis species and 1 Perinereis: N. arroyensis, N. largoensis, and P. diversidentata are regarded as valid species, and the synonymy of Nereis disparsetosa Treadwell, 1932 with Pseudonereis palpata (Treadwell, 1923) is confirmed. A commented table of the nereidid species proposed by Treadwell is also included.
