Face (Fig. 16) yellow, with transition crown-face black, sometimes red on dorsal portion of frons. Pronotum ( Fig. 14 ) yellow with small irregular-shaped black behind eye, posterior margin sometimes red, with or without transverse blacked band, that may be interrupted medially or not. Mesonotum and scutellum yellowish-brown. Forewing ( Figs 14 , 15) yellowish-brown to brownish-red. Legs yellow with tarsus darkened. Abdomem yellow ventrally; tergites red medially, lateral margins yellow.

Description. Abdominal sternite II (Fig. 7) with pair of internal apodemes long and straight, extending to posterior margin of sternite IV; apex rounded, not expanded laterally. External morphological characters as in generic description.

Male terminalia. Sternite VIII wider than long; approximately as long as sternite VII, with thin setae near lateral margins and posterior angles; posterior margin straight. Valve wider than long; posterior margin rounded. Pygofer (Fig. 8), in lateral view, 1.5 times longer than maximum height; ventral process elongated, arising from base and extended along ventral margin to almost pygofer apex, approximately straight distally; anteroventral surface convex, with many small, thin setae; ventral margin excavated; posterodorsal and posteroventral margins straight and convergent apically; apex rounded; macrosetae dispersed on posteroventral quadrant. Anal tube membranous, without processes. Subgenital plate, in lateral view (Fig. 8), produced posteriorly almost as far as pygofer apex; in ventral view (Fig. 9), elongated, 4.8 times longer than wide, wider near base and slightly tapered toward apex; ventral surface with many macrosetae, larger macrosetae near apical portion of inner margin; external margin with many long thin setae; apex rounded. Connective (Fig. 10) linear; ventral projection between arms, directed anterad; arms as wide as stem; stem elongate, abruptly wider medially, lateral margins parallel apically, with well developed dorsal keel; apex emarginated. Style, in dorsal view (Fig. 11), outer lobe rounded, with setae on inner surface; in lateral view (Fig. 12), blade elongated, without setae; ventral margin not serrated, with rounded projection basally; apex acute, curved dorsally. Aedeagus (Fig. 13) with atrium wide; preatrium developed and truncated; shaft flattened laterally and tapered distally, posterior margin carinated laterally; gonopore subapical on posterior surface. Other characteristics as in generic description.

Female terminalia. Sternite VII 1.5 times wider than long; ventral surface without setae; posterior margin approximately straight. Internal sternite VIII membranous. Pygofer (Fig. 17) 1.8 times longer than maximum height; ventral margin rounded; apex truncated; macrosetae dispersed on ventral half. First valvifer (Fig. 18) as long as high; lateral margins approximately straight; posterior angles rounded. First valvula (Fig. 18) with dorsal and ventral margins parallel, ca. 12 times longer than high; dorsal sculpturing starting at mid-length; apical portion (Fig. 19) with ventral sculpture present only near apex, continuous with the dorsal sculpture, apex abruptly tapered and acute. Second valvula (Fig. 20) ca. 10 times longer than high; apex (Fig. 21) with few irregular teeth. Second valvifer ca. 2.7 times higher than long. Gonoplac (Fig. 22) 5.3 times longer than high; dorsoapical margin long, almost parallel to ventral margin; apex rounded. Other characteristics as in generic description.

Etymology. The new species name comes from the Latin word “ tenebris ” that means dark. It refers to the coloration of the males, with dorsum predominantly black.
