Male genitalia
Vinculum curves posterodorsally, it's posterior ends free. Saccus small, ~triangular, with a rounded apex. Tegumen tubular, long. Gnathos median lobe narrow ovoid, recurved. Sacculus triangular - anteroventral margin rolled and strongly sclerotised, ending laterally in a short strong spine perpendicular to the plane of the valva, medial end produced posteriorly to articulate with juxta; posterodorsal margin straight, unadorned. Valvula elongate, extending much further laterally than the sacculus. Costa produced medially as a slightly angular transtilla. Juxta a short pedicle, fused to the tunica subbasally. Tunica simple with a tiny subapical tooth on the ventral side. Vesica about as long as tunica with a small comb of slender cornuti at its base (anterior end). no annulus or sclerotisation. Male genital key: In C.albicosta the small spinous process from the lateral end of the sacculus projects posteriorly beyond the margin of the sacculus; in C.vulnerariae a shorter tooth in a similar position does not cross the saccular margin.

Female genitalia
Anal papillae slightly blunt. Posterior apophyses ~2xOP. Anterior apophyses ~1.5xOP. Ostial plate elongate, rounded posteriorly. ostium large, U-shaped, central. No antrum. Ductus fairly straight in posterior ½, coiled in anterior ½. Sclerotisations: long flanked linear confluent in dorsal wall from ostium for >½ length of ductus, the bilinear flanks tapering at the anterior end of the line; circumferential moderately dense spiculation from ½OP anterior to AM for ~2OP. Junction with bursa gradual. Bursa elongate. Signum a medium-sized thorn with a broader than long ~semicircular base-plate and a slightly curved spike about as long as the shorter dimension of the base-plate.
