Micropeza dactyloptera , sp. n.

( Figs. 1–7 )

Etymology. The specific epithet refers to the Greek words daktylos (=finger) + pteron (=wing). It is allusive to a finger-shaped projection on the basal third of the costal vein in males.

Description. Male. ( Fig. 1–5 ) Body length, 6.7–9.1 mm. Head. Dorsal view, the anterior region of mesofrons, parafrons and lunule orange to brownish; front view, parafrons and parafacial pale yellow with fine silver setulae; lateral view, paracephala and gena pale yellow (with small bristles sparse), occiput black; mouthparts brownish; ocellar triangle brown; antenna brown with some large and small bristles black, arista brownish with bristles on basal third; inner and outer-vertical bristles, postvertical bristles black, well developed and nearly the same size. Thorax. General coloring black; pronotum pale yellow, disc of thorax and scutellum black; prosternum pale yellow; in lateral view, yellow macules on anepisternum, katepisternum and metakatepisternum; one notopleural, supra-alar, postalar and two scutellar apical bristles, all black.

Leg. Fore coxa black, trochanter yellow, femur yellow with apical half black, tibia, tarsus black; mid coxa and trochanter yellow, femur yellow with three black bands, tibia yellow with apex black, with a dense and long pilosity distally ( Fig. 2 ), tarsus black; hind coxa and trochanter black, femur yellow with three black bands, tibia yellow with apex black, two rows of bristles, tarsus black.

Wing. Hyaline or banded, costal vein densely hairy, on basal third the C vein have a finger-shaped projection ( Fig. 3 ), with small spines in the apex; R1, in dorsal view, with 8–10 setae long and sparse; r2 +3 with darker brown longitudinal macula underlying costal vein; r4+5 closed, forming a petiole.

Abdomen. Black and pale yellow in proximal portion of the first tergite and distal in others; sternites black with lateral margin pale yellow.

Terminalia. Sternite 5 with one pair of claspers with one strong and long hair apically and margin setose ( Figs. 4–5 ).

Female. ( Fig. 6-7 ) Body length, 6.2–9.1 mm. Similar to the male, except by absence of the finger-shaped projection in the costal vein and the long hairs on the mid tibia; ovipositor black and slender tapering towards apex; spermathecae small, rounded, one single and one pair ( Fig.7 ); ducts long.

Type material. The male HOLOTYPE is housed in the Coleção Entomológica do Departamento de Zoologia da Universidade de Brasília ( CEZUB), Brasília-DF, Brazil, and labeled: Brazil, Distrito Federal, Paranoá, 47º 38' 13" W, 15º 49' 42" S, 01/12/2009, Sevilha, E. col. [white label], UNB 012937 [white label]; Holotipo [red label]. The specimen is in excellent condition although the right antenna is broken.

Taxonomic note. M. dactyloptera sp. n. is easily distinguished from the other species of the genus by the presence of a finger-shaped projection on the costal vein of the male wing. This feature represents a sexual dimorphism for this species. The female diagnostic characters are the color patterns of the body, which is similar to male

Records of geographic distribution. Brazil: Goiás, Distrito Federal, Paraná.
