( Figs 1–11 View FIGURES 1–11 )

Description. Length based on alcohol preserved specimens. Male body length: 1.42 mm (n = 9), varying from 1.34 to 1.53; wing length: 1.12 mm (n = 9), varying from 0.98 to 1.30. Female, body length: 1.47 mm (n = 7), varying from 1.39 to 1.56. Wing length: 1.14 mm (n = 7), varying from 1.01 to 1.21. Head. Black, dichoptic. Eye dark reddish. Ocellar tubercle black, concolorous with occiput, with 3–4 pairs of tiny brown to black setae. Frons below medial ocellus as wide as high, subparallel sided, brown dorsally with 4 pairs of tiny lateral setae, yellow at lower part near antennae. Ocelli yellow, lateral ocellus separated from eye margin by approximately diameter of lateral ocellus. Face about twice as high as wide, brown, not protuberant beyond curve of eye. Mouth margin black. Postcranium and occiput black, subshining, sparsely brown dusted with covering of short blackish setae. Antenna ( Figs 1, 2 View FIGURES 1–11 ) dark brown to black; second flagellomere one-third length of first flagellomere; stylus apical, translucent ( Fig. 2 View FIGURES 1–11 ). Proboscis ( Fig. 1 View FIGURES 1–11 ) brown, robust, downward directed, slightly higher than head height (mainly in alcohol preserved specimens). Clypeus brown medially, yellow laterally and distally, with 4 pairs of setae, lower pair more robust. Labrum brown, shorter than longest diameter of eye, with minute teeth ventrally on each side. Palpus absent. Thorax. Pronotum and mesonotum black, subshining, lightly brown dusted. Mesonotum with rather inconspicuous yellow U-shaped mark from level of transverse suture to near base of scutellum (visible only in specimens preserved in alcohol). Disc of mesonotum with scattering of short black setae, rather randomly distributed but posterior dorsocentral line of more robust setae apparent, with posterior setae larger, reclinate. Scutellum black, subshining, with two pairs of setae, apical pair more robust. Postpronotal lobe yellow with 3 minute setae. Two supra-alar setae more robust than surrounding setae. Postalar callus yellow with small black seta. Mesopleuron brown, subshining, lightly brown dusted, except on black shining bare areas. Notopleuron with pair of more robust setae and 2–3 minute setae. Anepisternum with 4–5 minute setae dorsally, narrow yellow spotted anterodorsally (spot only anteriorly and dorsally visible in alcohol preserved specimens; spots extend posteriorly to white area just in front of and below wing base). Legs. Brown with apex of femora-tibial articulation yellow; distal half of tibiae and basal tarsomeres yellow, last two tarsomeres progressively darker. Wing ( Fig. 3 View FIGURES 1–11 ). Hyaline; veins brown; costa circumambient. Vein Sc incomplete, ending at about middle of Rs. Rs thinner at basal half. R 2+3 originating from Rs about two-thirds distance from R 1 to r-m crossvein. R 4+5 slightly sinuous. Vein M 1 more than two times length of cell dm, slightly downcurved distally. M 2 more distinctly curved than M 1. Crossvein r-m slightly beyond basal third of short cell dm. Crossvein dm-cu straight, slightly longer than m-m crossvein vein. CuA 1 and CuA 2 well developed to wing margin. A 1 short, ending at level of alular incision. Anal lobe normal. Halter with light brown stem, knob light yellow to whitish. Abdomen. Tergites brown, subshining. Tergites IV–VI with rather inconspicuous narrow pale yellow band across posterior margin. Sternites concolorous with tergites. Tergosternite VIII ( Fig. 5 View FIGURES 1–11 ) thin, almost complete circular band. Male genitalia ( Figs 4–8 View FIGURES 1–11 ). Brown, except extreme apex of epandrial projection and extreme apex of gonostylus black, subshining. Epandrium produced inwards posteroventrally ( Fig. 4 View FIGURES 1–11 ). Cercus subtriangular with small marginal setae on internal face ( Fig. 4 View FIGURES 1–11 ). Gonostylus fused, bifid at apex ( Figs 7, 8 View FIGURES 1–11 ). Anterior arm of aedeagal sheath elongate, thin ( Fig. 6 View FIGURES 1–11 ). Ejaculatory apodeme expanded distally. Lateral ejaculatory process ( Figs 5, 6 View FIGURES 1–11 ) rather translucent. Female genitalia. Tergite IX thinner than preabdominal tergites. Apical sternite longer than anterior ones. Vaginal furca as in Figure 9 View FIGURES 1–11 , with lateral arms slightly projected laterally; one short basal sperm duct; three spermathecae, each one same length with basal jarshaped sperm pump and spermathecal reservoir extremely elongate with microvilli tubules in two areas along duct ( Fig. 11 View FIGURES 1–11 ); spermathecal reservoir coiled distally ( Fig. 10 View FIGURES 1–11 ); each duct slightly dilated at apex and placed within spiral.

Etymology. The specific epithet is a noun in apposition and refers to the first name of Neri Pereira da Trindade, who helped us in the field collection.

Habitat. Specimens were hand-collected from unidentified flowers in Parque Nacional Serra das Confusões, Piauí state, Brazil, in typical Caatinga vegetation, one of the more arid areas in Brazil.
