Frontal callus margin divergent towards face. Arista-like terminal flagellomere with four setae basally ( Fig. 5 View FIGURES 1–6 ). Thorax. Legs entirely yellow, except hind tarsomeres white. Wing ( Fig. 31 View FIGURES 29–32 ). R 2+3 originating well beyond r–m, at a distance two times longer than r–m ( Fig. 37 View FIGURES 33–38 ). Alula with microtrichia only along anterior half ( Fig. 43 View FIGURES 39–44 ). Abdomen ( Fig. 54 View FIGURES 45–55 ). 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 View FIGURES 75–77 , 102–105 View FIGURES 96–105 ). Genital capsule as wide as high, its posterior margin weakly pointed dorsally; medial process of synsternite weakly developed ( Fig. 105 View FIGURES 96–105 ), 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 View FIGURES 75–77 ).

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 View FIGURE 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.
