Arista-like terminal flagellomere with four setae basally (Fig. 5). Thorax. Legs entirely yellow, except hind tarsomeres white. Wing (Fig. 31). R 2+3 originating well beyond r–m, at a distance two times longer than r–m (Fig. 37). Alula with microtrichia only along anterior half (Fig. 43). Abdomen (Fig. 54). Elongate, two times longer than wide, widest at fourth segment; entirely dark; tergites 1–3 with strong metallic green reflections, tergites 4–5 and sternites with coppery reflections; long golden pilosity laterally on tergites 1–3; short yellow pilosity on tergites 4–5 and sternites. Terminalia (Figs 75–77, 102–105). Genital capsule as wide as high, its posterior margin weakly pointed dorsally; medial process of synsternite weakly developed (Fig. 105), few thin setae apically. Anterior end of phallus distally to anterior margin of genitalia. Gonostylus at least two times longer than wide, pointed apically. Epandrium slightly wider than long (Fig. 75).
Female. Unknown.
Etymology. The specific epithet is feminine and it comes from the Greek word xanthos, meaning yellow, and podos, meaning foot, as a reference to the yellow leg color.
Geographic distribution. Mexico (Chiapas), Nicaragua (Matagalpa), Costa Rica (Puntarenas) (Fig. 130).
Comments. One additional specimen from Mexico (Chiapas) has the apical third of the hind femur dark brown, however, overall morphology and male genitalia fit with that of the other specimens.
