Plenotocepheus (Plenotocepheus) trinidadensis n. sp. differs from its most similar congener P. (Plenotocepheus) neotropicus Ermilov, Sandmann, Marian and Maraun, 2013 by the length of some notogastral setae and number of notogastral condyles. Generic and subgeneric diagnoses and an identification key to the known subgenera and species of Plenotocepheus are presented. ER -
