Ocellar triangle black; ocellar setae proclinate and developed (as long as frontal setae). Frontal vitta velvety black, golden pruinose, at the narrowest point two times wider than anterior width of ocellus (Fig. 13 A). Frontal setae 17. Fronto-orbital plate black, with silver pruinosity. Parafacial bare, brown with silver pruinosity. Frontogenal suture and gena silver pruinose. Gena brownish (Fig. 13 A). Pedicel with dorsal seta developed, with about a third of the length of arista. Postpedicel black, silver pilose, 3 times longer pedicel. Thorax. Scutum without vittae, with inconspicuous silver pruinosity on postpronotal and notopleural regions (Fig. 13 B). Acrostichal setulae biserial presuturally and triserial postsuturally. Dorsocentrals 2 + 3, long, the posteriormost postsutural pair slightly longer than the others. Prealar 2, the anterior one slightly longer. Katepisternum with about 10 long and thick setae ventrally (Fig. 13 C). Wing. Brownish, with the upper third between vein C and vein R 4 + 5 darker (Fig. 13 B). Calypters white. Haltere yellow, base of stem light brown. Legs.

(Figs 14, 15) Dichoptic (Fig. 14 A), similar to male, except: frontal vitta velvety black. 4 – 5 frontal setae (Fig. 14 A). Upper and lower orbital setae reclinate. Fronto-orbital plate shining black. Parafacial greyish pruinose (Fig. 14 A). Pedicel with 1 short seta. Fore tarsomere brown. Mid femur and tibia not modified. Mid femur with 1 row of short ad, av and pv setae, 5 long prepical setae connected to a row from p to pv. Mid tibia not constricted, with 1 supramedian pd, 1 submedian ad, and 1 preapical ad. Hind femur not modified, with a row of ad setae, 2 long submedian av setae, 1 preapical pd (Figs 14 B, 14 C). Abdomen rounded. Terminalia: cercus longer than epiproct (Fig. 15 A); hypoproct triangular and setulose, slightly longer than wide (Fig. 15 B); sternite 8 reduced to 2 separated plates with long setae; sternite 7 twice wider than its length; sternite 6 trapezoid (Fig. 15 B). Spermathecae 3, semicircular, one of them smaller with about half diameter of the other (Fig. 15 A). Morphological variation. The leg coloration varies from dark brown to light brown; some specimens have the sternite 5 more enlarged, as F. grisalesae (Fig. 3 G). The specimens from Chiapas have the wing slightly darker on the costal region, the surstyli slightly more enlarged apically and the lateral spike on surstyli more narrow and protruded.	en	Gomes, Lucas R.
