Diagnosis. The shorter pronotal and abdominal tergite IX setae separates this species from the similar F. cognata.

Distinguishing features. Color. Body dark, forewings dark, basally pale, legs dark, fore tibiae paler, hind tibiae basally pale (Fig. 56A). Pigmented ventral eye facets with the 1-1-2 pattern. Structure. Antennal segment VI with a transverse line of 3 small setae. Head with the PO1 setae, OC3 setae in position 2B (Fig. 56B). Pronotum usually with 4 mAM setae (Fig. 56B). Abdominal tergite I with transverse lines of sculpture between the campaniform sensilla (Fig. 56C). Upper surface of the hind coxae with microtrichia. Abdominal tergite VIII posteromarginal comb complete, microtrichia 19–22 µm (Fig. 56D).

Interception frequency. Common.

Region(s) of interceptions. South America.

Comments. This species is usually intercepted associated with Delphinium sp. cut flowers. Molecular data presented by Skarlinsky and Rugman–Jones (2023) revealed that specimens morphologically interpreted as F. xanthaner may be a complex of cryptic species.
