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.
