ETYMOLOGY: T he specific name is an arbitrary combination of letters.

DIAGNOSIS: Males resemble those of C. obtina (cf. figs. 439–449), but have a narrower, more angular distal embolar prong (figs. 516–521); females have two small sclerotizations reaching to near the anterior margin of the genital atrium (figs. 525, 526).

MALE (PBI_ OON 49595 View Materials , figs. 516–521): Total length 1.77. Endite ventral process relatively short, wide; dorsal process narrow, arched. Femur I r0-1-1; tibia I v4-4-1; metatarsus I v2-2-2. Embolus proximal prong with retrolaterally directed spur; distal prong with angularly notched tip (N = 5).

FEMALE (PBI_ OON 29768 View Materials , figs. 522–526): Total length 1.98. Spination typical. Genital atrium with pair of small sclerotizations near anterior margin (N = 1).
