Mesonotum (Figs 1 A, 2 A, C, E, 27 A, C), in dorsal view, yellow, usually with pair of darkened triangular maculae laterally, pair of darkened rounded maculae medially, sometimes smoky, and usually with a smoky darkened band on transverse sulcus. Forewing veins (Figs 1 A, B, 2 A, C, E, 27 A, C) distinctly paler, rarely indistinct. Abdomen (Fig. 3 B), in lateral view, yellowish ventrally and darkened dorsally. Legs (Fig. 1 B) yellowish, metasternum usually darkened. Specimens with overall color black (Figs 2 E, F, 27 C, D), with similar marks and maculae as described in pale-yellow coloration, but sometimes less distinct, abdomen entire black and legs smoky darkened. Females very rarely black. — Male terminalia: Pygofer (Fig. 1 D), in lateral view, posterior margin broadly rounded. Subgenital plate (Fig. 1 D), in lateral view, attaining pygofer half-length. Valve, (Fig. 1 E), in ventral view, margins subparallel and lateral margins rounded. Style (Fig. 1 F), in dorsal view, with preapical lobe. Aedeagus (Fig. 1 G, H), in lateral view, dorsal margin of shaft from slight to broadly rounded; ventral margin excavated basally and expanded distally, without processes; apex broadly rounded. Paraphysis (Fig. 1 I, J), in lateral view, curved ventrally, attaining pygofer apical third, with conspicuous preapical constriction on ventral margin and apex acute. Other features as in generic description. — Female terminalia: Sternite VII (Fig. 3 A – C), in ventral view, 1.8 × wider than long, posterior margin with a slight median lobe. Valvula II (Fig. 3 F – H) blade with 14 continuous triangular serrated teeth, without distinct gap in anterior margin of teeth. Other features (Fig. 3 D, E, I, J) as in generic description.

Remarks.

Specimens of C. albolineatus and C. platensis are the most abundant species amongst all studied specimens, and have external resemblances to each other, but they can be differentiated by the male genitalia characters presented in the former as: aedeagus with ventral margin lacking processes and paraphysis curved ventrally, with ventral margin bearing a preapical constriction. The specimens of C. albolineatus collected in “ Centro Politécnico, UFPR, Curitiba, Paraná ” and “ Parque Estadual Vila Velha, Ponta Grossa, Paraná ” presented a great number of males and a few females with black coloration. Even when specimens are black, they present the forewings with veins paler, unlike the other black specimens of Ciminius, like C. hartii, C. dissidens sp. nov. . males, and C. sesamum sp. nov. which present the veins mostly concolor with the membrane. Until the present moment, this species presents the only occurrence of black females for the genus.
