Forrestopius jumandi Alvarado sp. nov.

( Figs 3 , 10C )

Holotype. ♀ “ECUADOR’ Napo Baeza 2000m Feb. ’79 Mason ” ( USUC).

Diagnosis. This species can be recognized by the following combination of characters: mandible with two teeth, antenna with 18 flagellomeres, scape predominantly yellowish brown ( Fig. 3C ), face and clypeus forming a continuous surface, pronotum with a single wrinkle arising from pronotal pit with its upper end reaching about half of way to anterior margin and dorso-posterior corner yellowish brown, and propodeum with lateromedian and lateral longitudinal carinae. This species looks similar to F. auguratricis , F. runasimi and F. yungas but differs from them by having the area superomedia 2.5× as long as wide (vs. area superomedia 2.9–3.4× as long as wide).

Description. Female: Body length 7.1 mm. Fore wing length 4.6 mm.

Head. Face and clypeus forming a continuous surface, 0.9× as long as wide, smooth with punctures, upper quarter weakly striate; labrum not exposed when mandibles closed ( Fig. 3C ); mandibles with two teeth; malar space 0.9× as long as basal mandibular width; lateral ocellus separated from compound eye by about 1.2× maximum ocellar diameter; distance between ocelli 1.2× maximum ocellar diameter; vertex behind ocellar triangle slightly declivous, occiput concave; gena in lateral view 0.9× as long as compound eye; antenna with 18 flagellomeres, ratio of length from second to fourth flagellomeres: 1.0:0.9:0.9, subapical flagellomere 1.0× as long as centrally broad.

Mesosoma . Pronotum with wrinkle arising from pronotal pit, its upper end reaching about half of way to anterior margin; metapleuron polished with isolated setae, postero-ventrally smooth; submetapleural carina scrobiculate, anteriorly expanded into conspicuous triangular lobe. Propodeum with lateromedian longitudinal carina strong, slightly closer to each other anteriorly ( Fig. 3B ); lateral longitudinal carina complete; posterior transverse carina present; area superomedia 2.5× as long as wide. Fore wing with vein Cu 1 a between Cu 1 b and 2 m-cu 2.6× as long as Cu 1 between Rs & M and 1 m-cu; 2 rs-m 1.0× 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 1.6× as long as posteriorly wide ( Fig. 3B ), lateromedian carina extending 0.6× length of tergite; tergite II 1.0× as long as posteriorly wide; laterotergite II 0.1× as wide as long; laterotergite III 0.6× as wide as long, wedge-shaped, mesal edge convex.

Colour. Head extensively black, mandible and scape yellowish brown, palpi testaceous; pedicel and flagellomeres brown. Mesosoma black, dorso-posterior corner of pronotum and subalar prominence yellowish brown, tegula yellow; fore and mid leg yellow, coxae testaceous; hind leg yellow, coxa brown and dorsally gradually changing to testaceous, trochanter, trochantellus, basal third of femur, distal fifth of tibia and tarsomere light brown. Metasomal tergites dark brown with soft metallic blue reflection, metasomal tergites II–V distal margin and laterotergites brownish; valvae testaceous.

Male: Unknown

Remarks. This species occurs in a Cloud forest at the Eastern slopes of the Andes of Ecuador, at 2000m ( Fig. 10C ).

Etymology. The specific epithet jumandi is in honor the indigenous hero Jumandi who rose up against the Spanish colonizers in 1578, in nowadays Ecuadorian province Napo. It is treated as a noun in apposition.
