Diagnosis. – Cyclocosmia can be easily distinguished from all other ctenizids by its distinctly truncate abdomen forming a caudal disc bearing ribs and grooves. Although two other genera, Galeosoma and Idiosoma of the family Idiopidae , have similar abdominal form, they are not closely related to Cyclocosmia . These idiopid spiders possess eyes arranged in three rows rather than two, which is characteristic for ctenizids. In addition, the abdomen of the genus Galeosoma is abruptly truncate but bears no ribs or grooves, whereas that of the genus Idiosoma bears ribs or grooves but is only moderately truncate (Gertsch & Platnick, 1975).
Description. – See Gertsch & Platnick (1975).
