Diagnosis. The pseudotegumen folded outwards posteriorly, a unique condition within the genus as are the phallus with two diverticula only on its antero-ventral portion, and the inward folded fultura inferior.

Examined material (in total 2 ♂). Bolivia. Cochabamba. 1 ♂ , HT; 1 ♂, Chapare, Locotal, 1200 m: 1 ♂, X.2019, Calderón-Villavicencio leg. ( CGCM 42.521 ; CGCM) .

Male ( Pl. 3 View PLATE 3 : Fig. 15–16 View PLATE 2 View PLATE 3 , Pl. 10: Fig. 14 View PLATE 2 ). Forewing length: 19 mm, wingspan: 40 mm.

Male genitalia (Pl. 15: Fig. 4 View PLATE 1 , Pl. 19: Fig. 14 View PLATE 2 ). Saccus with posterior edge concave. Tegumen rectangular, slightly curved. Tergal lobes protruded posteriorly. Pseudotegumen less reinforced anteriorly than posteriorly, the latter expanded latero-posteriorly and folded outwards. Fultura inferior rectangular, twice as wide as long, posterior margin inward folded. Valvae apically pointed (not visible in the Pl. 15: Fig. 4 View PLATE 1 ).

Female. Unknown.

Distribution. Known from two localities in Cochabamba, Bolivia (Pl. 28: Fig. 1 View PLATE 1 ).

Remarks. Viette (1961) figured the male genitalia in the original description, so here the male is figured for the first time.

d) Species-group: endyra . Six species: C. claudia sp. nov., C. endyra , C. hannelore sp. nov., C. mirna sp. nov., C. monique sp. nov., and C. ykeyra .

Defined by the phallus shape with a distal bladder, that when everted, comprises three mesal diverticula (posterior, mesal, and ventral) (Pl. 20: Fig. 1–6 View PLATE 1 ). In addition by: i) male sternite VIII uniformly sclerotised and shows the posterior margin obtuse; ii) tegumen extended beyond articulation with saccus; iii) tergal lobes crab claw-shaped with or without projections; iv) pseudotegumen ribbed and expanded mesally; v) valvae digitiform and ribbed, and; vi) plates of the lamella antevaginalis with mesal corner projected and tapered.

Distribution. Coastal and mainland between Espírito Santo in southeastern Brazil and Santa Catarina in southern Brazil at altitudes between about 600 and 2200 m (Pl. 26: Fig. 1 View PLATE 1 ).
