Figs. 2‑12

Type material: Holotype: male, BRAZIL, Bahia, Igrapiúna, Reserva Ecológica Michelin, Vila 5, 28.v-12. vii.2012, Malaise [trap]. Aragão, M.; Menezes, E.; Mota, E.; Andena, S, leg. ( MZFS #56225 ) . Paratypes: 6 males, same data as holotype ( MZFS #56227 , # 56229 , # 56230 , # 56231 , # 56232 , # 56233 ) ; 2 males, same locality as holotype, 27-28.x. 2012, light [trap], Aragão, M., Menezes, E., Mota, E. leg. ( MZFS #56226 , # 56234 ) ; 1 male, same locality as holotype, 28.x-18.xi.2012, Malaise [trap], Aragão, M., Menezes, E. leg. ( MZFS #56228 ) .

Description: Male: Head: slightly wider than long; short vertex; eye bridge with four facet rows; eyes separated by almost one facet diameter; interocular suture inverted Y-shaped ( Fig. 2 ). Antenna: scape wider apically than at base, 2.0 times the length of the pedicel ( Fig. 3 ); pedicel spherical, with two groups of three small sensorial setae both in front of and behind the proximal margin ( Fig. 6 ); flagellum with 14 flagellomeres, all cylindrical ( Figs. 3-5 ); ascoids not observed,probably lost;14 th flagellomere with long apiculus, 0.3 times the length of the flagellomere ( Fig. 5 ). Wing ( Fig. 8 ): Sc short not reaching C; R₂₊₃ not connected to R₄; R₅ ending slightly beyond the wing apex; radial fork basal to medial fork. Terminalia: hypandrium bent backwards, narrower laterally ( Fig. 9 ); gonocoxites 1.2 times the length of gonostyli, with setae only dorsally ( Figs. 9, 11 ); gonostyli bifurcate; lateral branch of gonostylus longer than mesal branch ( Figs. 9, 10 ), divergent in lateral view ( Fig. 10 ); aedeagus bipartite, asymmetrical, short shaft 0.8 times the length of the long shaft; short shaft with two sclerites fused basally, dorsal sclerite platelike, shorter than the narrow ventral sclerite, both covered by an apical membrane ( Fig. 9 ); parameres asymmetrical, long shaft with curved apex and short shaft plate-like with rounded apex ( Figs. 9, 11 ); gonocoxal apodemes fused medially and articulated with parameres ( Fig. 11 ); epandrium wider than long, bare ventrally, with one basal aperture ( Fig. 12 ); hypoproct longer than epandrium, with apex tapered; epiproct shorter than hypoproct, with rounded apex; hypoproct and epiproct both with apical micropilosity ( Fig. 12 ); cerci with two tenacula ( Fig. 12 ).

Female: Unknown.

Remarks: The new species can be distinguished from oth- er species of Tonnoira by the eye bridge with four facet rows, separated by 0.5 facet diameter; R₅ ending slightly posterior to apex of wing; gonostyli bifurcated, dorsal arm shorter than ventral arm;long arm of gonostyli shorter than length of gonocoxites; cerci with two tenacula; aedeagus bipartite, asymmetrical, short shaft 0.8 times the length of the long shaft; parameres asymmetrical, longer shaft with apex curved.The gonostylus is similar to that of T.andradei Santos, 2014 , but differs, mainly, by the bifid aedeagus in the new species and with only one shaft in T.andradei . The ejaculatory apodeme and hypoproct in the new species is longer than the same structures in T.andradei .

Etymology: The species name is a reference to the municipality of Igrapiúna where the specimens of the new species were collected.

Distribution: Known only from the type locality.
