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.

4.75 mm
; Wing length 3.22−4.74, mean
4.19 mm
; wing width 1.09−2.50, mean

4.16 mm
; wing length 3.38−4.51, mean
3.97 mm
; wing width 1.14−1.49, mean
