Diagnosis.

Overall coloration (Figs 13 A, B View Figure 13 , 15 A, B View Figure 15 , 29 C View Figure 29 ) dark-brown to black with paler markings on crown, pronotum anterior third, and at least on veins of anterior portion of forewings. Aedeagus (14 G), in lateral view, ventral margin rounded and expanded, with rugosities preapically; apical portion not expanded, apex rounded. Paraphysis (Figs 14 I, J View Figure 14 ) directed posterodorsally, slightly curved dorsally, with dorsal and ventral margins subparallel, bearing a subapical constriction dorsally.

Description.

Measurements: Total length: males (n = 1) 4.7 mm; females (n = 1) 5.7 mm. — Head and Thorax: Crown (Figs 13 B View Figure 13 , 14 A View Figure 14 , 29 C View Figure 29 ), in dorsal view, slightly produced, anterior margin subtriangular; median length approximately 1 / 3 of intraocular width, and 1 / 4 of transocular width. Ocelli located slightly posteriorly of imaginary line between anterior eyes angles. Frons (Figs 13 A View Figure 13 , 14 B View Figure 14 ), in lateral view, slightly inflated. Pronotum width approximately equal to transocular width. Other features as in genus description. — Coloration: Overall coloration of male black (Figs 14 A – C View Figure 14 ). Crown and face (Figs 14 A, C View Figure 14 ) with yellow markings in ocelli and muscular impressions. Clypeus, gena and lorum yellow. Pronotum (Fig. 14 A View Figure 14 ) anterior third with yellow markings, black posteriorly, with posterior margin yellow. Mesonotum black. Forewings veins yellow basally (Figs 14 A, B View Figure 14 ). Legs yellow (Fig. 13 B, C View Figure 13 ). Female overall coloration yellow (Figs 13 View Figure 13 , 29 C View Figure 29 ). Crown and pronotum (Figs 13 B View Figure 13 , 29 C View Figure 29 ) anterior third with darker markings. Frons (Figs 13 View Figure 13 , 29 D View Figure 29 ) with darker areas in muscular impressions. Forewings (Figs 13 A, B View Figure 13 , 29 C, D View Figure 29 ) browned, with veins paler. Abdomen (Figs 13 D View Figure 13 , 15 A, B View Figure 15 ), yellow, with darkened portions. — Male terminalia: Pygofer (Fig. 14 D View Figure 14 ), in lateral view, posterior margin broadly rounded. Subgenital plate (Fig. 14 D View Figure 14 ), in lateral view, attaining pygofer apical portion. Valve (Fig. 14 E View Figure 14 ), in ventral view, anterior and posterior margins subparallel; lateral margins narrowly rounded. Style (Fig. 14 F View Figure 14 ), in dorsal view, with a pair of slight dentate processes on outer margin, one basally and other preapically. Aedeagus (Fig. 14 G, H View Figure 14 ), in lateral view, shaft expanded, ventral margin rounded, apical portion rugulose, apical portion not expanded, apex rounded. Paraphysis (Fig. 14 I View Figure 14 ), in lateral view, directed posterodorsally, curved dorsally, reaching pygofer apical third; dorsal and ventral margins subparallel, dorsal margin with a small dentate process basally, apex subacute; in dorsal view (Fig. 14 J View Figure 14 ), lateral margins with small reentrances preapically. Other features as in generic description. — Female genitalia: Sternite VII (Figs 13 D View Figure 13 , 15 A – C View Figure 15 ), in ventral view, almost 2.2 × wider than long, posterior margin with a distinctly acute median lobe. Valvula II (Fig. 15 F – H View Figure 15 ) blade with 18 continuous subtriangular serrated teeth, with a distinct gap in anterior margin of teeth. Other features (Fig. 15 D, E, I, J View Figure 15 ) as in generic description.

Remarks.

Ciminius taosus is the largest member of Ciminius . The males of C. taosus can be differentiated in coloration from the other black species by the forewings with yellow longitudinal veins, fading towards apex, and the crown and frons contrasting yellow and black marks. In dorsal view (Figs 12 B View Figure 12 , 13 A View Figure 13 , 28 C View Figure 28 ), the crown is longer, as in lateral view (Figs 12 A View Figure 12 , 13 B View Figure 13 ), the frons is more inflated compared to the remaining species of the genus. The aedeagus of C. taosus is similar to C. sidanus and C. hartii , but the ventral margin is more expanded than in the former and the apex is not expanded as in the latter. Otherwise, the paraphysis in C. taosus is curved dorsally, while in C. sidanus and C. hartii it is rectilinear.
