( Figs 1–14 )

Etymology. The noun in apposition refers to the place where the specimens were collected, Parque Estadual do Mirador, Maranhão state, Brazil.

Holotype ♂. Body length: 4.4 mm.

Diagnosis. Frontal pruinosity velvety black. Palpus light brown to brown, orange on distal half. Tergite 6 about 4X shorter than syntergosternite 7+8, longer laterally.

Head ( Figs 1–3 ). Frontal pruinosity velvety black, with evanescent dorsal vitta projecting laterally to ocellar triangle ( Fig. 2 ). Height 1.66X the length; width 1.5X the height. Frons 1.8X wider than long. Fronto-orbital plate with gray-yellowish pruinosity in frontal view ( Fig. 2 ). Genal groove area brown, large, bare; gena predominantly gray pruinose; postgena with brown pruinosity ( Fig. 3 ). Antenna with arista yellowish at base ( Fig. 3 ). Palpus light brown to brown, orange on distal half.

Thorax. Mesonotum dark brown to black; when seen from dorsal view and with lateral and dorsal incident light with dense gray pruinose stripe between dorsocentral setae, reaching third dorsocentral setae pair ( Fig. 4 ); when seen with anterior incident light also with distinct gray pruinosity on posterior margin. Scutellum dark brown to black; in dorsal view with distinct gray pruinosity when seen under anterior incident light. Legs ( Fig. 1 ). Coxae and femora brown to dark brown. Tibiae light brown, yellowish on proximal ¼. Tarsi dark yellow to light brown. Wing ( Fig. 5 ). Mainly hyaline, slightly brown infuscated on cell c and beginning of cell r1. Length 3.5 mm, width 1.3 mm, 2.7X longer than wide.

Abdomen ( Fig. 6 ). Male terminalia. Tergite 6 narrow dorsally, about 4X shorter than syntergosternite 7+8, longer laterally ( Figs 7–8 ). Epandrium with scattered setae on posterior half. Cercus ( Figs 7–9 ) longer than midlongitudinal line of epandrium, divergent distally, with sparse setae on anterior margin and outer surface. Hypandrium 3X longer than epandrium ( Figs 9–10 ). Phallapodeme 2.23X longer than hypandrium ( Fig. 9 ). Basiphallus almost as long as distiphallus ( Figs 7, 9 ). Distiphallus suboval and slightly bilobate distally in ventral view ( Figs 8, 10, 12 ). In ventral view, pregonite with distal mesial keel with margin nearly truncate; postgonite subtriangular ( Fig. 10 ). Gonocoxal apodemes upward directed, apparently loosely fused when seen from posterior view ( Fig. 11 ).

Female similar to male. Terminalia ( Figs 13–14 ). Tergite 6 as in the male. Sternite 6 with small median triangular sclerite, with the point directed posteriorly, bare; with two posterolateral small sclerites, weakly sclerotized. Tergite 7 strongly fused with sternite 7; posterior ¾ with long, thin and sparse setae. Epiproct small, plate-like. Cerci brown setose, separated, elongated and thin.

Variations. Male (n = 4). Body length 3.62−5.32, mean 4.75 mm; Wing length 3.22−4.74, mean 4.19 mm; wing width 1.09−2.50, mean 1.69 mm. Female (n = 4). Body length 3.25−4.67, mean 4.16 mm; wing length 3.38−4.51, mean 3.97 mm; wing width 1.14−1.49, mean 1.34 mm.
