Clypeus black. Gena and lorum yellowed. Mesonotum (Fig. 25 A) black anteriorly to transversal sulcus and yellow posteriorly. Forewings (Fig. 25 A, B) veins dark. Legs yellow. Abdomen, in lateral view, blackened, bordered with yellow. Males, rarely pale-yellow like the females (Fig. 26), mostly with overall coloration black (Fig. 25 A – C). Females with overall coloration pale-yellow (Figs 30 E, F, 51), with features as described in  C. albolineatus. — Male terminalia: Pygofer (Fig. 25 D), in lateral view, posterior margin rounded, slightly narrowed apically. Subgenital plate (Fig. 25 D), in lateral view, slightly surpassing half-length of pygofer. Valve (Fig. 25 E), in ventral view, margins subparallel, lateral margins subacute anteriorly. Style (Fig. 25 F), in dorsal view, without dentate process preapically. Aedeagus (Fig. 25 G, H), in lateral view, shaft slightly protuberant, ventral margin anterior two-thirds serrated, apical portion not dentate, expanded, apex rounded, forming a hood-like structure. Paraphysis (Fig. 25 I, J), in lateral view, directed posterodorsally, rectilinear, reaching pygofer apical third, dorsal and ventral margins subparallel, apex from acute to subacute. Other features as in generic description. — Female genitalia: Sternite VII (Fig. 27 A – C), in ventral view, 2 × wider than long, posterior margin with a distinctly median lobe. Valvula II (Fig. 27 F – H) blade with 18 continuous subtriangular serrated teeth, with a distinct gap in anterior margin of teeth. Other features (Fig. 27 D, E, I, J) as in genus description.   Figure 26.   Ciminius sesamum  sp. nov., color variation in male, habitus. Adorsal view; Bfrontal view.   Figure 27.   Ciminius sesamum  sp. nov., female paratype. Adistal portion of abdomen, ventral view; Bdistal portion of abdomen, lateral view; Csternite VII, ventral view; Dfirst valvifer and first valvula, lateral view; Eapical portion of first valvula; Fsecond valvula, lateral view; Gmedian portion of second valvula; Hapical portion of second valvula; Isecond valvifer and gonoplac, lateral view; Japical portion of gonoplac.

This is a noun in apposition.   Remarks.   Ciminius sesamum  sp. nov.resemble externally to other black males of the genus:  C. hartii,  C. yana,  C. albolineatus, and  C. dissidens  sp. nov., however,  C. sesamum  sp. nov.have a more homogeneous black aspect, with indistinct or faint yellow marks along the crown and pronotum. The only constant yellow mark is in the posterior half of the mesonotum. In the aedeagus,  C. sesamum  sp. nov.can be distinguished from  C. yanadue to absence of a lobate distinct process on dorsal margin, distinguished from  C. hartiiand  C. albolineatusdue to the aedeagus bearing the ventral margin serrated, and from  C. dissidens  sp. nov., due the aedeagus not strongly widened in lateral view. In the locality of CentroPolitécnico, mostly females presented a submacroptery condition (Fig. 50), which is discussed furthermore. 5189131310 2017-04-08 2017-04-22 2017-04-08 sweep DZUP A. C.
