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.
