6CC312A825DBE6603D4E045F5EEF0E8D.taxon	diagnosis	Diagnosis. The genus Cyclocosmia differs from all the other genera of Ctenizidae by the abruptly truncated abdomen forming a heavily sclerotized disc that is enhanced by a series of raised ribs and grooves (Gertsch and Platnick 1975) (Fig. 1 B-D, I-L). Genera Galeosoma and Idiosoma of the family Idiopidae have the similar abdominal form as Cyclocosmia, but the genus Galeosoma can be distinguished from Cyclocosmia by the distinctly truncated abdomen without ribs or grooves, and the genus Idiosoma can be distinguished from Cyclocosmia by the moderately truncated abdomen, even though with ribs or grooves. Moreover, the arrangement of eyes is also different, Cyclocosmia with two eye rows, yet the two genera of Idiopidae with three eye rows (Gertsch and Platnick 1975; Zhu et al. 2006).	en	Xu, Xin, Xu, Chen, Li, Fan, Pham, Dinh Sac, Li, Daiqin (2017): Trapdoor spiders of the genus Cyclocosmia Ausserer, 1871 from China and Vietnam (Araneae, Ctenizidae).

D11C78DEE1CC35CE11B9DB9BCCCD7E25.taxon	diagnosis	Diagnosis. Cyclocosmia ricketti differs from other species of Cyclocosmia by the character of 23 - 33 radiating ribs on each side of abdominal disc (Fig. 1 I-L), and parallel-sided spermathecae (Fig. 1 G, H). It can be distinguished from Cyclocosmia latusicosta by the lack of the elevated central zone inside the upper pair of muscle impressions (Fig. 1 I-L).
