(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.
