Diagnosis. This species can be recognized by the following combination of characters: mandible with two teeth, antenna with 20 flagellomeres, scape predominantly yellowish brown, face and clypeus forming a continuous surface, pronotum with a single wrinkle arising from pronotal pit ( Fig. 7C View FIGURE 7 ) which upper end reaches about two third of way to anterior margin and dorso-posterior corner yellowish brown, propodeum with lateromedian and lateral longitudinal carinae ( Fig. 7B View FIGURE 7 ), and metatarsomeres light brown ( Fig. 7A View FIGURE 7 ). This species looks similar to F. auguratricis , F. jumandi and F. yungas but differs from them by having the submetapleural carina smooth (vs. submetapleural carina scrobiculate).

Description. Female: Body length 8.2 mm. Fore wing length 5.5 mm.

Head. Face and clypeus forming a continuous surface, 1.0× as long as wide, smooth with punctures, upper quarter weakly striate ( Fig. 7D View FIGURE 7 ); labrum not exposed when mandibles closed; mandibles with two teeth; malar space 1.2× as long as basal mandibular width; lateral ocellus separated from compound eye by about 1.1× maximum ocellar diameter; distance between ocelli 1.2× maximum ocellar diameter; vertex behind ocellar triangle slightly declivous, occiput concave; gena in lateral view 1.0× as long as compound eye; antenna with 20 flagellomeres, ratio of length from second to fourth flagellomeres: 0.7:0.7:0.7, subapical flagellomere elongate, 1.1× as long as centrally broad.

Mesosoma . Pronotum with wrinkle arising from pronotal pit, its upper end reaching about two third of way to anterior margin ( Fig. 7C View FIGURE 7 ); metapleuron polished with isolated setae, posteroventrally striate; submetapleural carina smooth, anteriorly expanded into triangular lobe. Propodeum with lateromedian longitudinal carina strong, slightly closer to each other anteriorly ( Fig. 7B View FIGURE 7 ); lateral longitudinal carina complete; posterior transverse carina present; area superomedia+petiolaris 2.9× as long as wide. Fore wing with vein Cu 1 a between Cu 1 b and 2 m-cu 1.7× as long as Cu 1 between Rs & M and 1 m-cu; 2 rs-m 0.6× as long as abscissa of M between 2 rs-m and 2 m-cu. Hind wing with distal abscissa of M indistinguishable, distal abscissa of Cu 1 and 1 A sclerotized throughout. Outer metatibial spur 0.7× as long as inner spur.

Metasoma. Tergite I 1.4× as long as posteriorly wide ( Fig. 7B View FIGURE 7 ), lateromedian carina extending 0.5× length of tergite, smooth with isolated punctures on the apical half (absent centrally); tergite II 0.9× as long as posteriorly wide; laterotergite II 0.2× as wide as long; laterotergite III 0.5× as wide as long, wedge-shaped, mesal edge straight.

Colour. Head black, mandibles yellowish brown, scape, distal third of pedicel, and palpi yellow; basal 2/3 of pedicel and flagellomeres brown. Mesosoma black except dorso-posterior corner of pronotum yellowish brown and tegula yellow; fore and mid legs yellow, mid coxa dorsally light brown; hind leg with coxa and basal 2/3 of femur black, distal 1/3 of femur and basal 2/3 of tibia yellow; trochanter, trochantellus, 1/3 distal of tibia and tarsomeres light brown. Metasomal tergites dark brown with soft metallic blue reflection, metasomal tergites II–V distal margin and laterotergites brownish; ovipositor and valvae testaceous.

Male: Unknown

Remarks. This species was collected in a wet forest in Peru at 1520m ( Fig. 10A View FIGURE 10 ); it occurs in the same locality as F. yungas sp. nov.

Etymology. The specific epithet runasimi means ‘people’s language’ in the Quechua language. It is treated as a noun in apposition.
