Comments. Structure. Most similar to F. yucatanica , but differs by having the following features: Mesopleuron polished smooth, ventral half punctate (vs. polished smooth, centro-anteriorly with transversal striation, ventral half punctate); clypeus anterior margin centrally without teeth (vs. with two small tubercles); APH 0.69 (vs. 0.54); notaulus reaching about 0.45–0.49 of mesoscutum length (vs. 0.32); AWH 0.71–0.75 (vs. 0.84); epicnemial carina ending at pronotal spiracle (vs. ending above pronotoal spiracle); epomia after diverging from pronotal collar distinctly curved (vs. approximately straight); MSM 0.34 (vs. 0.28).

Also similar to F. panamensis , from which it differs by having the following features: Clypeus anterior margin centrally without teeth (vs. with two small tubercles); mesopleuron polished smooth, ventral half punctate (vs. polished smooth, centro-anteriorly with transversal striation, ventral half punctate); epicnemial carina reaching about 0.7 of distance to subalar ridge (vs. reaching about 0.8 of distance to subalar ridge); OST 1.25–1.38 (vs. 1.58– 1.59); fore wing crossvein 1m-cu fully continuous with 1-Rs+M (vs. limit between 1m-cu and 1-Rs+M more or less traceable); epicnemial carina ending at pronotal spiracle (vs. ending above pronotoal spiracle); HW1C 1.70–2.00 (vs. 1.30–1.49); hind wing vein Cub almost straight, very slightly convex (vs. distinctly convex on posterior half, otherwise straight; supra-antennal area with slight median line (vs. median line distinct and straight).

Also similar to F. exelysae , but differs by having the following features: Clypeus anterior margin centrally without teeth (vs. with two small tubercles); mesopleuron polished smooth, ventral half punctate (vs. polished smooth, centro-anteriorly with transversal striation, ventral half punctate); area behind anterior transverse carina transversally strigate, arched posteriorwards (vs. transversally strigate, generally weak, antero-laterally faint); scuto-scutellar groove with vestigial longitudinal wrinkles (vs. with distinct longitudinal wrinkles; epicnemial carina reaching about 0.7 of distance to subalar ridge (vs. reaching about 0.8 of distance to subalar ridge); median depression of T1 elongate, very shallow (vs. drop-shaped, distinct, large); supra-antennal area with slight median line (vs. median line distinct and straight).

Color pattern. Closest to F. shakira , from which it differs by having dorsal margin of pronotum whitish (vs. black); orbital band interrupted between 1–4 h (vs. interrupted between 6 –7 h); scape ventrally whitish (vs. dark brown); and clypeus entirely whitish (vs. apical e lateral margins blackish).

Also similar to F. exelysae , from which it differs by having tergites bright orange (vs. black, posteriorly with whitish stripes); scape ventrally whitish (vs. dark brown); hind t1 basally yellowish (vs. blackish); propodeum entirely bright orange (vs. posteriorly with pale yellow mark); and hind tibia apically blackish (vs. yellow).

Etymology. The word frida is a free feminine approximation for Alfredo, from Alfredo Chaves, the type locality.
