Araújo & Bravo
sp. nov.
(
Figs. 25A–I
)
Diagnosis.
R4+5 complete at base; r-m present; arm of gonocoxite directed to midline, apically bifurcated and with a group of elongated bristles in the center; one pair of lanciform projections in the aedeagal complex; aedeagus ending after the apex of projections in the aedeagal complex; ejaculatory apodeme short, 0.5 times the length of medial expansion of gonocoxite; cercus with apical projection with two setae.
Description. Male.
Head subcircular in frontal view. Antenna with 13 flagellomeres; scape about the same length as the subspherical pedicel; flagellomeres pyriform, eccentric (
Figs 25A, 25B
); basal ascoids 1.7 times the length of flagellomere (
Fig. 25D
); 13th flagellomere subcylindrical with terminal apiculus separated by a suture (
Fig. 25B
). Palpus with three segments; 1st segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.9:0.9 (
Fig. 25C
). Wing. R4+5 complete at base; r-m present; m-cu absent (
Fig. 25E
). Male terminalia: Hypandrium fused with gonocoxites with a pair of medial lanciform expansion. Gonocoxites with posterior arm directed to midline, apically bifurcate and with a group of elongated bristles in the center. Gonostylus articulated to gonocoxite at the middle, bare, with apex directed upward (
Fig. 25G
). Projections in the aedeagal complex, one pair, lanciform. Aedeagus ending after the apex of projections in the aedeagal complex (
Fig. 25H
). Ejaculatory apodeme short, 0.5 times the length of medial expansion of gonocoxite. Epandrium pilose, posteriorly wider than anteriorly. Cercus pilose, piriform, with apical elongated projection with two setae (
Figs. 25G,
25I
). Epiproct shorter than hypoproct, both with apical micropilosity (
Fig. 25G
).
