Figures 22, 23, 24, 30 C, D, 50 C

Diagnosis.

Coloration black (males) (Fig. 22 A, B) or reddish (Figs 23, 24 C, D, 30 C) (females, rarely males). Aedeagus (Fig. 22 G, H) shaft distinctly wide in lateral view, ventral margin entirely serrated, apical portion expanded, apex broadly rounded, forming a hood-like structure. Paraphysis (Fig. 22 I, J) almost straight, ventral and dorsal margins converging apically.

Description.

Measurements: Total length: holotype male 3.9 mm; paratypes, males (n = 19) 3.8–4.2 mm; females (n = 20) 4.6–5.2 mm. — Head and Thorax: Crown (Figs 22 A, B, 23 A, 30 C), in dorsal view, slightly produced, anterior margin often subtriangular, rarely broadly rounded, median length from 1 / 6 to 1 / 5 of intraocular width, and about 1 / 3 of transocular width. Ocelli located slightly before the imaginary line between anterior eye angles. Pronotum width approximately equal to transocular width. Other features as in generic description. — Coloration: Females (Fig. 30 C) with crown and pronotum browned, with marks and maculae as in C. albolineatus . Forewings distinctly reddish, with veins yellow. Abdomen (Figs 24 A – C, 50 C), in ventral view, darkened, with lateral margins and terminalia yellow, prosternum and metasternum darkened. Legs yellow. Other features as described in C. albolineatus . Males rarely as females (Fig. 23), mostly with overall coloration black (Fig. 22 A – C), with marks, bands, and maculae as in C. albolineatus, but with marks often reddish and smoother. Face (Figs 22 C, 23 B, 30 D), with yellow marks on muscular impressions, often with a yellow longitudinal band medially. Clypeus darkened with yellowed areas medially. Gena and lorum yellow with darkened areas. Pronotum (Figs 22 A, 23 A, 30 C) posterior third often entirely black. Forewing (Fig. 22 B) black, veins concolor, except costal margin, R + M stem and basal portion of claval suture and Pcu yellowish or reddish. Abdomen darkened, lateral margins yellow. — Male terminalia: Pygofer (Fig. 22 D), in lateral view, posterior margin rounded. Subgenital plate (Fig. 22 D), in lateral view, slightly surpass half of pygofer. Valve (Fig. 22 E), in ventral view, margins subparallel, lateral margins subacute. Style (Fig. 22 F), in dorsal view, with preapical lobe. Aedeagus (Figs 22 G, H), in lateral view, conspicuously wide; shaft slightly protuberant dorsally; ventral margin entirely serrated; apical portion expanded, apex rounded, forming a hood-like structure. Paraphysis (Fig. 22 I, J), in lateral view, directed posteroventrally, almost straight, not attaining pygofer apical third, apex subacute. Other features as in generic description. — Female terminalia: Sternite VII (Fig. 24 A – C), in ventral view, 1.7 × wider than long, posterior margin with a nearly indistinct median lobe. Valvula II (Fig. 24 F, G) blade with 18 continuous triangular serrated teeth, without a distinct gap on anterior margin of teeth. Other features (Fig. 24 D, E, I, J) as in generic description.

Etymology.

The epithet “ dissidens ” means “ different ” in Latim. It refers to the reddish coloration of females that can also occur in males, and is different from any other color pattern known in Ciminius . This is a noun in apposition.

Remarks.

The black males of Ciminius dissidens sp. nov. resemble C. hartii, C. yana, C. sesamum sp. nov. and the black male specimens of C. albolineatus, due to their coloration and size. Although Ciminius dissidens sp. nov. tends to present more distinct yellow areas on the pronotum and head, and reddish portions laterally, different from Ciminius sesamum sp. nov. and C. yana . In addition, the forewing veins are never yellow, differing from C. albolineatus . Ciminius dissidens sp. nov. males can be distinguished from the other Ciminius species by the distinct wide aspect of the aedeagus in lateral view, with serrated processes along the entire ventral margin. The females of C. dissidens sp. nov., stand out for their distinct reddish forewing coloration. In a total of 44 males of C. dissidens sp. nov. studied, 40 males were black and only four were reddish.
