Genus Colossendeis Jarzinsky, 1870

Remarks: Child (1995a) commented: “The Antarctic species of this genus need a thorough revision but I leave this difficult task to a future student of the Pycnogonida.” He also reported Colossendeis megalonyx ssp. from the shelf and slope off Buenos Aires Province ( Argentina) on the basis of material collected by the RV Islas Orcadas (37°24´S– 54°39´7W, 182–327 m). Child recorded great variation in size, and in morphometric relationships between proboscis, femur, and tibia. These considerations, as well as those made below for C. geoffroyi , highlight the need for a revision of Antarctic and Subantarctic species of Colossendeis ( Cano & López-González 2007; Krabbe et al. 2010).
