Ciminius yana Young 1977

Ciminius yana Young Figures 16, 17, 18, 19, 29 E, F Ciminius yana Young, 1977: 593. Diagnosis. Coloration pale-yellow (Fig. 29 E, F) to brown (females and rarely males) (Fig. 18) or black (males) (Figs 16, 17 A – C), with R + M and base of CuP veins yellow. Aedeagus (Fig. 17 G, H) with shaft strongly protuberant, forming a preapical lobate process on dorsal margin, directed apically. Paraphysis (Fig. 17 I, J) curved ventrally, with a preapical constriction on ventral margin. Description. Measurements: Total length: males (n = 11) 3.2–3.7 mm, females (n = 6) 3.9–4.3 mm. — Head and Thorax: Crown (Figs 17 A, B, 18 A, 29 E), in dorsal view, from slightly to moderately produced, anterior margin from broadly rounded to subtriangular. Median length of crown from 3 / 7 to 1 / 2 of intraocular width, and about 1 / 4 of transocular width. Pronotum width slightly greater than transocular width. Ocelli aligned to imaginary line between anterior eye angles. Other features as in genus description. — Coloration: Overall coloration from pale-yellow (Fig. 29 E, F) to brown (Fig. 18), as described in C. albolineatus, especially in females. Males usually with overall coloration black (Figs 16, 17 A, B), with marks, bands and maculae as described in C. albolineatus. Face (Figs 17 C) with yellow marks on muscular impressions, often with yellow longitudinal band medially. Clypeus browned. Gena and lorum black with margins yellow. Forewings (Figs 16, 17 A, B) with veins black, except costal cell, basis of claval suture and basis of R + M and C veins distinctly yellow. Legs (Fig. 17 B, C) yellowish. Abdomen black, lateral margins yellowish. — Male terminalia: Pygofer (Fig. 17 D), in lateral view, posterior margin broadly rounded. Subgenital plate (Fig. 17 D), in lateral view, slightly exceeding posteriorly half-length of pygofer. Valve (Fig. 17 E), in ventral view, anterior and posterior margins slightly converging medially; lateral margins rounded. Style (Fig. 17 F), in dorsal view, without preapical lobe. Aedeagus (Fig. 17 G, H), in lateral view, shaft with a preapical lobate process, directed apically; ventral margin without processes; apical portion not expanded, apex rounded. Paraphysis (Fig. 17 I, J), in lateral view, curved and directed posteroventrally, almost attaining pygofer apical third, with a preapical constriction on ventral margin, apex subacute. Other features as in genus description. — Female terminalia: Sternite VII (Fig. 19 A – C), in ventral view, 1.9 × wider than long, posterior margin with median lobe distinct, rounded. Valvula II (Fig. 19 F – H) blade with 13 continuous subtriangular serrated teeth, without distinct gap in anterior margin of teeth. Other features (Figs 19 D, E, I, J) as in genus description.

Remarks. The black males of C. yana resemble Ciminius dissidens sp. nov .. and Ciminius sesamum sp. nov. but can be distinguished due to the distinct yellow markings on claval suture and basis of R + M and C veins. The pale-yellow to brown males are more similar to C. albolineatus and C. platensis. Furthermore, males of C. yana can be distinguished from other congeners by the conspicuous lobate process on the aedeagus dorsal margin. From all the studied material, a unique black specimen of C. yana presented forewings venation that was completely yellow.
