The family Chromadoridae (Nematoda) in the Canary Islands

Abstract

Three species of the family Chromadoridae were collected during an ecological study of the intertidal and shallow soft-bottoms of two beaches in Tenerife. Two of these species were determined to genus level: Actinonema sp and Hypodontolaimus sp, due to the lack of adult specimens in the first genus and the presence of aduhs in poor conditions in the second. Another species recorded was Ptycholaimellus ponticus (Filipjev, 1922). Descriptions, figures and meristic data of each species are presented, as well as, autoecological data from sampling stations.
