ABSTRACTABSTRACTEucynorta quadripustulata (Simon, 1879), the type species of the third most diverse genus in Cosmetidae, Eucynorta Roewer, 1912 Roewer CF. 1912. Die Familie der Cosmetiden Opiliones-Laniatores. Archiv für Naturgeschichte. 78(10):1–122. [Google Scholar], was described for 'Colombia' and after more than a century, a more specific locality was not known. Based on the examination of abundant material from several collections, including the type material, we were able to better establish its geographic distribution in the Caribbean littoral of Colombia. A redescription of the species, emended diagnosis and comments about the status of the genus are offered. Finally, based on the morphology of the type species, we assigned the genus, originally in Cosmetinae Koch, 1839, to the subfamily Cynortinae Mello-Leitão, 1933.KEYWORDS: Colombian Caribbean coastEucynorta QuadripustulataGonyleptoideaLaniatores Disclosure statementNo potential conflict of interest was reported by the author(s).AcknowledgmentsWe are thankful to Gustavo Miranda (USNM) and Carine Gonçalves who gave special attention to the MM in his visit to Washington.
