Comments. Structure. Most similar to F. yucatanica , but differs by having the following features: OST 1.58– 1.59 (vs. 1.37); T1LW 2.67–2.85 (vs. 2.54); MSM 0.33–0.39 (vs. 0.28); HW1C 1.30–1.49 (vs. 1.76); sternaulus weakly sinuous (vs. strongly sinuous); epicnemial carina reaching about 0.8 of distance to subalar ridge (vs. reaching about 0.7 of distance to subalar ridge); MLW 1.55–1.67 (vs. 1.44).

Also similar to F. frida , from which it differs by having the following features: Clypeus anterior margin centrally with two small tubercles (vs. without teeth); mesopleuron polished smooth, centro-anteriorly with transversal striation, ventral half punctate (vs. polished smooth, ventral half punctate); OST 1.58–1.59 (vs. 1.25–1.38); HW1C 1.30–1.49 (vs. 1.70–2.00); epicnemial carina ending above pronotoal spiracle (vs. ending at pronotal spiracle); limit between fore wing crossvein 1m-cu and 1-Rs+M more or less traceable (vs. fully continuous with 1-Rs+M); sternaulus weakly sinuous (vs. strongly sinuous; epicnemial carina reaching about 0.8 of distance to subalar ridge (vs. reaching about 0.7 of distance to subalar ridge).

Also similar to F. exelysae , but differs by having the following features: Area behind anterior transverse carina transversally strigate, arched posteriorwards (vs. transversally strigate, generally weak, antero-laterally faint); scutoscutellar groove with vestigial longitudinal wrinkles (vs. with distinct longitudinal wrinkles); median depression of T1 elongate, very shallow (vs. drop-shaped, distinct, large); T2–8 from distinctly coriarious T2 to smooth T8 (vs. faintly coriarious).

Color pattern. Closest to F. shakira , from which it differs by having tergites black, posteriorly with whitish stripes (vs. bright orange); and antenna with white band composed by fl5 apical 0.55, fl6–12, and fl13 basal 0.40 (vs. by f5 apical 0.20, f6–10 and most of fl11).

Also similar to F. exelysae , from which it differs by having epicnemium entirely light orange (vs. mostly or almost entirely black); dorsal margin of pronotum black (vs. pale yellow); and propodeum posteriorly without pale yellow mark (vs. with pale yellow mark).

Also similar to F. yucatanica , from which it differs by having propodeum posteriorly without pale yellow mark (vs. with pale yellow mark); hind coxa dorsally without whitish spot (vs. with distinct whitish spot centrally); and scape ventrally dark brown, or with yellow spot (vs. whitish).

Etymology. The specific epithet refers to the country where the holotype was collected.
