Fragosa tenuis species group

Description. Head. Face wholly pale; tubercle convex and ventrally positioned (Fig. 81). Frons narrow (less than 1/3 of head width) and pale on ventral 1/4 to 1/2 lateral to lunule (Fig. 82). Frons/frontal triangle smooth. Frontal triangle white microtrichia homogeneously distributed but oriented ventro-dorsally (only visible from a ventral view) (Fig. 81). Female ocellar triangle separated by more than its length from the posterior eye margin (Fig. 82). Dorsal occiput with microtrichia oriented ventro-dorsally (Figs 80, 82). Dorsal occiput with 1–2 rows of pile (Fig. 82). Thorax. Scutum shiny black. Metathoracic epimera extended dorsal to the metacoxa but not so close to each other as in the F. rugosifrons group (Fig. 79). Metafemur with sub-apical dark band (Fig. 80). Wing. Female wing hyaline basally and gradually turning light brown towards apex; female wing bare on basal 1/3 to 2/3 of c, and bases of br and bm. Terminalia. Male epandrium and hypandrium of similar size (Figs 92, 94); surstylus sub-quadrangular with slightly extended apex (Fig. 93, 94); subepandrial sclerite rectangular and wide, with basal corners slightly extended and round (Fig. 95).

Included species (6): F. aurora (Hull, 1943c) comb. nov. [1b], F. filissima (Hull, 1943a) comb. nov. [1a], F. macer (Curran, 1930a) comb. nov. [1b], F. tenuis (Walker, 1852) comb. nov. [2, type lost], F. titania (Hull, 1943a) comb. nov. [1b], F. virgilio (Hull, 1942b) comb. nov. [1a].

Comments. Fragosa aurora (Fig. 74) and F. virgilio (Fig. 76) were previously allocated to the O. lepidus group (Mengual et al. 2018). However, the type specimen of F. virgilio and photos of the type and the original description of F. aurora were studied and they show the distinct very narrow and long 2 nd abdominal segment that defines the genus Fragosa, and the pale smooth frontal triangle that defines the F. tenuis group.
