(Figs 7, 10A)  
 Holotype. ♀ “ PERU: CU, San Pedro, 13°03’22”S / 71°32’55.2”W, 1520m, 22.ix.2007, Malaise11, C. Castillo ” (MUSM).   
 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) 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), and metatarsomeres light brown (Fig. 7A). 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); 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); 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); 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), 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); 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.
