Etymology. Named in honor to the collector of the specimen, Francisco Felipe Xavier Filho (INPA, Brazil).

Description. Holotype ♂. Body length 4.85 mm.

Diagnosis. Antenna entirely black, including arista. Gena brown pruinose. Palpus dark brown to black, brown at extreme distal tip. Tergite 6 asymmetrical, restricted to the right side, very short, inconspicuous medially.

Head ( Figs 57–59 ). Frontal pruinosity velvety dark brown, with distinct dorsal vitta projecting laterally to ocellar triangle reaching vertex area ( Fig. 58 ). Height 1.33X the length; width 1.2X the height. Frons 1.5 wider than long. Fronto-orbital plate with gray-yellowish pruinosity in frontal view ( Fig. 58 ). Genal groove area brown, large, bare; gena brown pruinose; postgena with brown to dark brown pruinosity ( Fig. 59 ). Antenna entirely black, including arista ( Fig. 57 ). Palpus dark brown to black, brown at extreme distal tip.

Thorax ( Fig. 60 ). Mesonotum dark brown to black with a faint gray pruinose stripe between dorsocentral setae, reaching third dorsocentral setae pair, more distinct when seen under anterior incident light. Scutellum dark brown to black; in dorsal view with conspicuous gray pruinosity when seen under anterior incident light. Legs ( Fig. 57 ). Coxae and femora brown to dark brown. Tibiae mainly brown somewhat yellowish medially. Tarsi brown. Wing ( Fig. 61 ). Hyaline. Length 4.4 mm, width 1.5 mm, 2.9X longer than wide.

Abdomen ( Fig. 62 ). Male terminalia. Tergite 6 asymmetrical, restricted to right side, very thin and short, inconspicuous medially ( Fig. 64 ); syntergosternite 7+8 largely fused. Epandrium with some scattered setae and a single row on posterior edge ( Figs 63–64 ). Cercus almost 3X longer than wide, slightly shorter than epandrium, setose ( Figs 63–64 ). Hypandrium 1.8X longer than epandrium ( Figs 63, 65 ). Phallapodeme 2.4X longer than hypandrium ( Figs 63–64 ). Basiphallus as long as distiphallus ( Fig. 63 ). Distiphallus subhemispherical in ventral view, with a small fissure distally ( Fig. 65 ). In ventral view pregonite with distal mesial keel subrounded; postgonite as a small thin sclerite ( Fig. 65 ). Gonocoxal apodemes upward directed, apparently not fused when seen from posterior view ( Fig. 66 ).

Female. Unknown.
