Etymology: The specific epithet (Latin adjective: doubled) alludes to the presence of two pairs of claw-shaped structures in the internal sac of the aedeagus.

Description: Body length 1.0– 1.1 mm. Eye rudiments minute, composed of three or four weakly defined ommatidia without pigmentation. Other external and male secondary sexual characters as in the preceding species, except as follows:

: metaventrite depressed in the middle; aedeagus ( Fig. 62–64 View Figs 59–69 ) approximately 0.23 mm long; internal sac with two pairs of large and strongly curved claw-shaped structures, with an additional pair of weakly curved spines, and with a transverse apico-median structure; paramere apically extending beyond apex of median lobe, with short apical seta.

Intraspecific variation: The males from Termessos differ from those from other localities by slightly longer and more slender weakly curved structures (i.e., the most basal pair of internal structures). However, since slight variation was observed also in the shapes of the remaining structures and between specimens from all localities, and since no other evidence was found suggesting that these populations should represent distinct species, the observed differences are attributed to intraspecific variation.

Comparative notes: This species is reliably distinguished from the preceding representatives of the C. unguicum subgroup by the presence of three pairs of large sclerotized spines in the internal sac of the aedeagus.

Distribution and natural history: The known distribution of C. geminum is confined to the west of Antalya province, Southwest Anatolia ( Map 3 View Map 3 ). The specimens were sifted from litter in oak and pine forests and in a north slope with cedar, cypress, and oak shrubs at altitudes of 325–1255 m.
