Crown length 0.9x or more than interocular width (22A1,A2); aedeagus with pair of relatively long apical processes, length of each process more than 3x median width; aedeagus without unpaired apical process................................ 2 1’. Crown length 0.8x or less than interocular width (25A); aedeagus with pair of short apical tooth-like processes, each process not longer than 1.5x median width (26H); aedeagus with unpaired apical process (26H)............................. 3 2. Aedeagus symmetrical; apical processes of aedeagus very thin, forming semicircles in caudal view............. C. adama 2’. Aedeagus asymmetrical; apical processes of aedeagus thicker, sinuate, not forming semicircles in caudal view... C. cyphora 3. Aedeagus shaft relatively stout, symmetrical (25H,I); unpaired apical process short, not strongly recurved and paralleling shaft (25H); paired apical processes larger, triangular (25H); dorsal side of aedeagal base not excavated (25H); sclerotized phragma plates in caudal view not bent medially below anal tube, separated from each other, broadly rounded (25R).. C. obrienorum 3’. Aedeagus shaft gracile, slightly asymmetrical (26H); unpaired apical process long, recurved and paralleling shaft (26H); paired apical processes smaller, toothlike (26H); dorsal side of aedeagal base excavated (26H); phragma sides in caudal view bent mesad below anal tube, paralleling and close to each other throughout length to bulbous base (26Q)................... 4 4. Unpaired apical process of aedeagus widely separated from shaft (26H); apex of unpaired process distinctly bent caudad, not as widely flared (26H); dorsal side of aedeagal base more deeply excavated (26H); basal half of aedeagal shaft parallel to caudoventral margin of base of aedeagus (26H)....................................................... C. otamendi 4’. Unpaired apical process of aedeagus closely paralleling shaft or overlapping; apex of unpaired process not or only gradually bent caudad, distinctly flared; dorsal side of aedeagal base more shallowly excavated; basal half of aedeagal shaft not parallel to caudoventral margin of base of aedeagus, directed more dorsad....................................
