Diagnosis.

Coloration pale-yellow (Figs 10 A, B View Figure 10 , 11 A, B View Figure 11 , 29 A View Figure 29 ), with longitudinal paler stripes on forewings and orangish marks on pronotum and mesonotum anterior thirds. Aedeagus (Fig. 11 G, H View Figure 11 ) ventral margin with slightly rugosities preapically, shaft expanded, apical portion not expanded, apex rounded. Paraphysis (Fig. 11 I, J View Figure 11 ) directed posterodorsally, rectilinear, dorsal and ventral margins subparallel.

Description.

Measurements: Total length: males (n = 3) 3.8–4.0 mm; females (n = 3) 4.6–5.0 mm. — Head and thorax: Crown (Figs 10 B View Figure 10 , 11 A View Figure 11 , 29 A View Figure 29 ), in dorsal view, slightly produced, anterior margin subtriangular or rounded. Median length of crown from 1 / 4 to 1 / 2 of intraocular width, and from 1 / 4 to 1 / 3 of transocular width. Pronotum width approximately equal to transocular width. Ocelli located slightly posteriorly of imaginary line between anterior eyes angles. Other features as in generic description. — Coloration: Overall coloration yellow. Crown (Figs 10 B View Figure 10 , 11 A – C View Figure 11 , 29 A, B View Figure 29 ) with pair of small black spots at apex. Frons (Figs 10 C View Figure 10 , 11 C View Figure 11 , 29 B View Figure 29 ) with darker areas on muscular impressions. Pronotum (Figs 10 B View Figure 10 , 11 A View Figure 11 , 29 A View Figure 29 ) anterior third orangish, disc browned, posterior margin brown or yellow. Forewings (Figs 10 A, B View Figure 10 , 11 A, B View Figure 11 , 29 A View Figure 29 ) brown to dark-brown, with longitudinal yellow stripes on lateral margins of clavus, anterior portion of M vein, and costal margin. Legs and abdomen (Figs 10 A, B, D View Figure 10 , 11 B View Figure 11 , 12 A, B View Figure 12 ) without dark markings. — Male terminalia: Pygofer (Fig. 11 D View Figure 11 ), in lateral view, posterior margin broadly rounded. Subgenital plate (Fig. 11 D View Figure 11 ), in lateral view, attaining pygofer apical portion. Valve (Fig. 11 E View Figure 11 ), in ventral view, margins subparallel, lateral margins acute anteriorly. Style (Fig. 11 G View Figure 11 ), in dorsal view, with a slight dentate preapical process on outer margin. Aedeagus (Fig. 11 G, H View Figure 11 ), in lateral view, shaft expanded, ventral margin with anteriorly projected process; apical portion slightly rugulose, apex rounded. Paraphysis (Fig. 11 I View Figure 11 ), in lateral view, directed posterodorsally, rectilinear, reaching pygofer apical third; dorsal and ventral margins subparallel, apex subacute; in dorsal view (Fig. 11 J View Figure 11 ), sinuous preapically. Other features as in generic description. — Female genitalia: Sternite VII (Figs 10 D View Figure 10 , 12 A – C View Figure 12 ), in ventral view, 1.7 × wider than long, posterior margin with a distinctly rounded median lobe. Valvula II (Fig. 12 F – H View Figure 12 ) blade with 14 continuous subtriangular serrated teeth. Other features (Fig. 12 D, E, I, J View Figure 12 ) as in generic description.

Remarks.

Ciminius sidanus presents a unique coloration in Ciminius , which is responsible for its easy recognition. Otherwise, the male genitalia assemble with C. hartii differentiating in a few features, as the presence of rugosities basally on aedeagus ventral margin and aedeagus apex expanded, while in C. sidanus the rugosities are restricted to preapical portion and the aedeagus apex is not expanded in lateral view. Although the separation of these two species is possible using the coloration and male genitalia, the similarities between them are strong, which suggest the necessity of a future molecular analysis to confirm their status as separate species.
