Abstract

Teratocyclops cubensis Plesa, 1981 (Copepoda, Cyclopidae) is redescribed on the basis of specimens deposited in the collection of the Speleological Institute Emil Racovitza, Cluj, Romania. The genus Teratocyclops Plesa, 1981 is redefined, mainly characterized by the following characters of the female: the general habitus of the body, the 11-segmented antennule, the presence of the vestigial exopodite on the antenna, the segmentation of the swimming legs, the structure of the distal segment of the endopodite of leg P4 with 1 spine and 3 setae, and the proximal segment of leg 5 fused to the somite. The relationship to the closely related genera Metacyclops Kiefer, 1927, Apocyclops Lindberg, 1942, and Goniocyclops Kiefer, 1955 are discussed. Teratocyclops cubensis Plesa, 1981 (Copepoda, Cyclopidae) est redecrit a partir des specimens deposes dans les collections de l'Institutul de Speologie Emil Racovitza, de Cluj, Roumanie. Le genre Teratocyclops Plesa, 1981 est redefini. Il est principalement caracterise par les traits suivants de la femelle: la forme generale du corps, l'antennule a 11 segments, la presence de l'exopodite vestigial sur l'antenne, la segmentation des pattes natatoires et l'ornementation du dernier segment de l'endopodite de P4 comprenant 1 soie et 3 epines, le segment proximal de P5 soude au somite. Les affinites avec les genres voisins, notamment Metacyclops Kiefer, 1927, Apocyclops Lindberg, 1942 et Goniocyclops Kiefer, 1955 sont discutees.
