Five new records of comesomatids (Nematoda, Chromadorida) from the Canary Islands

Abstract

Five species belonging to the family Comesomatidae were recorded in an ecological study of the intertidal sandy seabeds on the south coast of Tenerife. These species were: Actarjania sp. 1, Actarjania sp. 2 Laimella aff. longicauda Cobb, 1920, Paramesonchium belgium Jensen, 1976 and Vasostoma sp. The first two species were detennined to genus level due to the lack of material in good conditions and the latter was represented by only one anterior fragment. Descriptions, figures and meristic data of each species are presented.
