Interactive key to the Cylindroleberididae

Anna Syme, August 2006

Ostracods of the family Cylindroleberididae are identified by fine setal combs attaching ventrally to the maxilla and the fifth limb. Nearly all species also have 3-7 pairs of gills attaching to the posterior of the body. A checklist to all species in the family (219) is available (Syme and Poore, 2006 : see main page for reference list), with details about type localities and references to full species descriptions.

Taxonomically well-known species (133) are included in this interactive key, with 66 morphological characters. Figures of appendages and other features are presented here, below (scroll down). The characters are those of adult female specimens, unless noted otherwise in the character description. It is recommended that identifications made using the key are confirmed with the species description (referenced in the checklist). Most species descriptions use more characters than are included in the interactive key. It is also likely that many new specimens will in fact be new species, particularly when sampled from a relatively un-studied geographic region.
