Morphometry. See Table 1, Figs 20–21, and Appendix.
Variation. Fore wing vein 3-M distinctly shorter than 2-M; mesopleuron sometimes centro-anteriorly polished smooth, without transversal striation; anterior transverse carina medially slightly arched forwards. Orbital band complete (5 of 13 specimens) or incomplete (8/13), briefly interrupted near 2, 3, or 4 h, or interrupted between 2–4 h; malar space black; scape rarely ventrally with yellowish mark; propodeum rarely posteriorly without distinct pale yellow area; clypeal groove sometimes black marked; hind coxa rarely dorsally with weak pale yellow spot; epicnemium dorsal 0.40-0.95 black, or entirely black; T1 sometimes basally orange. Specimen from Camamú (BA) has propodeum posteriorly with brown marks, and T1 black, posteriorly with whitish stripe.
Male (Fig. 3). Same overall structure and color pattern as female, but with the following differences. Antenna with 31 flagellomeres (vs. 22–24 in female). Clypeus apico-ventrally dark brown; propodeum posteriorly without pale yellow area; scutellar carina pale yellow; T1 dorso-anteriorly bright orange; and orbital band almost complete, briefly interrupted between 09:00–09:30 h. Specimen from Sinop, Mato Grosso, with propleuron dark brown; and mesepisternum without mid anterior pale yellow spot.
Comments. Structure. Most similar to F. panamensis, from which it differs by having the following features: Epomia after diverging from pronotal collar approximately straight (vs. distinctly curved); scuto-scutellar groove with distinct longitudinal wrinkles (vs. with vestigial longitudinal wrinkles); area behind anterior transverse carina transversally strigate, generally weak, antero-laterally faint (vs. transversally strigate, arched posteriorwards); anterior transverse carina medially straight (vs. slightly arched forwards); epicnemial carina ending at pronotal spiracle (vs. ending above pronotoal spiracle); hind wing vein Cub almost straight, very slightly convex (vs. distinctly convex on posterior half, otherwise straight); T2–8 faintly coriarious (vs. from distinctly coriarious T2 to smooth T8); median depression of T1 drop-shaped, distinct, large (vs. elongate, very shallow).
Also similar to F. sacha, but differs by having the following features: OST 1.43–1.54 (vs. 1.70); sternaulus weakly sinuous (vs. strongly sinuous); area behind anterior transverse carina transversally strigate, generally weak, antero-laterally faint (vs. transversally strigate, arched posteriorwards); fore wing crossvein 1m-cu more or less uniformly curved (vs. basally bent, otherwise straight); crossvein 3r-m spectral (vs. nebulous); T2–8 faintly coriarious (vs. from distinctly coriarious T2 to smooth T8); median depression of T1 drop-shaped, distinct, large (vs. elongate, very shallow).
Also similar to F. yucatanica, but differs by having the following features: Scuto-scutellar groove with distinct longitudinal wrinkles (vs. with vestigial longitudinal wrinkles); area behind anterior transverse carina transversally strigate, generally weak, antero-laterally faint (vs. transversally strigate, arched posteriorwards); supra-antennal area with median line distinct and straight (vs. with slight median line); notaulus reaching about 0.39–0.54 of mesoscutum length (vs. 0.32); epicnemial carina reaching about 0.8 of distance to subalar ridge (vs. reaching about 0.7 of distance to subalar ridge); T2–8 faintly coriarious (vs. from distinctly coriarious T2 to smooth T8); sternaulus weakly sinuous (vs. strongly sinuous; median depression of T1 drop-shaped, distinct, large (vs. elongate, very shallow); anterior transverse carina medially straight (vs. slightly arched forwards).
Color pattern. Closest to F. yucatanica, from which it differs by having scape ventrally dark brown (vs. whitish); mid coxa entirely light orange (vs. dorsally with whitish area); and hind coxa without or with faint whitish spot dorsally (vs. with distinct whitish spot dorsally).
Also similar to F. panamensis, from which it differs by having epicnemium mostly or almost entirely black (vs. entirely light orange); dorsal margin of pronotum pale yellow (vs. black); and propodeum posteriorly with pale yellow mark (vs. without pale yellow mark).
Etymology. From the Greek exelysis, feminine, meaning outlet, mouth of a river. In reference to the location of the holotype.
