Diagnosis.
Coloration pale-yellow (Figs 20 A – C View Figure 20 , 30 A, B View Figure 30 ), with copper marks on crown and forewings; claval suture and R + M veins whitened. Aedeagus (Fig. 20 G, H View Figure 20 ) basidorsal portion expanded, ventral margin from shallowly to deeply excavated basally, serrated medially, rectilinear subapically; apical portion expanded, apex rounded forming a hood-like structure. Paraphysis (Fig. 20 I, J View Figure 20 ) directed posterodorsally, with a preapical constriction on ventral margin.
Description.
Measurements: Total length: holotype male 4.0 mm; paratypes, males (n = 11) 4.0– 4.3 mm; females (n = 5) 4.5–4.63 mm. — Head and Thorax: Crown (Figs 20 A, B View Figure 20 , 30 A View Figure 30 ), in dorsal view, slightly produced, anterior margin subtriangular; median length from 2 / 7 to 1 / 2 of intraocular width, and about 2 / 5 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: Overall coloration pale-yellow (Figs 20 A – C View Figure 20 , 30 A, B View Figure 30 ). Crown (Figs 20 A View Figure 20 , 30 A View Figure 30 ), in dorsal view, with distinct browned areas. Pronotum, in dorsal view, anterior third with distinct browned marks and darkened maculae, posterior third smoky paler. Forewing (Figs 20 A, B View Figure 20 , 30 A View Figure 30 ) with cubital and first anal veins copper-brown; R + M vein, claval suture whitened, other veins yellow. Other features as in C. albolineatus description. — Male terminalia: Pygofer (Fig. 20 D View Figure 20 ), in lateral view, posterior margin rounded, slightly tapering towards apex. Subgenital plate (Fig. 20 D View Figure 20 ), in lateral view, almost reaching pygofer half-length. Valve (Fig. 20 E View Figure 20 ), in ventral view, margins subparallel, lateral margins subacute. Style (Fig. 20 F View Figure 20 ), in dorsal view, with a slight dentate process medially in outer margin. Aedeagus (Fig. 20 G, H View Figure 20 ), in lateral view, shaft from slightly to broadly protuberant, ventral margin from shallowly to deeply excavated basally, with serrated processes medially, rectilinear subapically; apical portion expanded, apex rounded, forming a hood-like structure. Paraphysis (Fig. 20 I, J View Figure 20 ), in lateral view, rectilinear, directed posterodorsally, almost reaching pygofer apical third, with a conspicuous preapical constriction on ventral margin, apex acute. Other features as in generic description. — Female terminalia: Sternite VII (Fig. 21 A – C View Figure 21 ), in ventral view, 1.9 × wider than long; posterior margin shallowly excavated each side of a small and distinct median lobe. Valvula II (Fig. 21 F – H View Figure 21 ) blade with 14 continuous triangular serrated teeth, without a distinct gap in anterior margin of teeth. Other features (Fig. 21 D, E, I, J View Figure 21 ) as in generic description.

Etymology.
The epithet “ autumnalis ” means “ from autumn ” in Latim, and refers to the specimens’ coloration, reminding autumn leaves. This is a noun in apposition.
Remarks.
Ciminius autumnalis sp. nov. resembles C. albolineatus and C. platensis due to their size and overall coloration. Ciminius autumnalis sp. nov. can be differentiated from the other Ciminius species by the following male genitalia aspects: the aedeagus dorsal margin distinctly rounded dorsally, ventral margin serrated medially and rectilinear subapically; and paraphysis rectilinae, directed dorsally, with a distinct preapical constriction ventrally. The specimens of C. autumnalis sp. nov. presents variations in the aedeagus. In seven specimens studied, there were variations in shaft roundness, which can be strongly or moderately rounded dorsally, and in basiventral margin, which can be rectilinear or with a reentrance. The most distinct patterns were provided in the illustration (Fig. 19 G View Figure 19 ). The paraphysis structure presented a variation in curvature degree, from slight to distinctly curved, but the shape remaining the same.
