Diagnosis: Similar to C. berau sp. nov., distinguished from this and other known congeners by distinctive shape of E (posterior half bottle-shaped, anterior half filiform, tip pointed; Figs 52-53), C (straight prolateral margin, broadest at midpoint, hooked tip; Figs 52-53) and RTA (tapering, pointed tip; Figs 52-54). Females can be distinguished by the round spermathecae, and by short CD not being longer than the width of the wall of S (Figs 55-56). Specimens of both sexes are smaller and lighter in color than specimens of C. berau sp. nov.

Etymology: Named after the ancient Greek mythological figure Phaidra.
