( Figs 1B View FIGURE 1 , 2D View FIGURE 2 )

Diagnosis. This species is easily recognized by having the dorsal margin of harpe sinuous, the dorsal margin apex almost straight, the basal cover plate very narrow and the basivolsella without protuberance.The tergal process of this species is very similar to coronatus species-group.

Description. Head. Mandible with two distal teeth. Median clypeal lobe trapezoidal, with one angulate tooth; median clypeal carina low in profile, complete or nearly so, straight in profile or nearly so. Frons coriaceous, punctures small and dense. Vertex crest weakly incurved. Dorsal pronotal area with anterior margin coarse. Tergal process submedian, with dense tuft of setae inside of shallow depression. Posterior hypopygeal margin straight or nearly so. Genitalia. Harpe slightly wide basally, apical margin straight, abaxial margin not projected; gonostipes shorter than harpe, ventral margin not excavated until outer margin of basivolsella; digitus short, basidorsal corner poorly projected; basivolsella without protuberance, without spines; aedeagal ventral valve with apex anterior to apex of dorsal one, wide, abruptly narrowing apicad; inner margin outcurved; outer margin outcurved, curved laterad; aedeagal dorsal valve narrow, with two pairs of apical lobe; outer lobe long, narrow, apical margin rounded and posterad; apex of inner median filament anterior to apex of lobe, directed slightly laterad; basal cover plate entirely narrow, posterior margin rounded; apodeme extending beyond genital ring.

Material examined. Holotype, 1♂: VENEZUELA, Táchira, 8 Km SE San Cristóbal, 1425–1450m, 23– 31.V.1998, FIT Ashe, Brooks, Hanley ( CNCI) . Paratype: 1♂, same data as holotype ( CNCI) .
