Evanioidea Online

Lower face uniformly brown [Morphbank], setose medially, sparsely setose laterally. Torulus at midline of eye. Area between toruli without carina but raised as smooth, convex area. Eye 0.4 times head height. Epistomal declivity of clypeus short, diverging slightly. Gena nitid, denudate. Malar space 0.67 times eye height. Clypeal process evenly round, not pinched in appearance [Morphbank]. Vertex defined by slight, irregular surface sculpture. Scape and pedicel light brown to yellow. Flagellomere evenly brown. Mandible light brown, with 3 reddish teeth on anterior face (4 teeth total).

Less rhomboid and more rectangular; more strongly sculpted than other species and covered in long setae [Morphbank]. Propleuron rugose. Ventral half of mesopleuron areolate, medially nitid (anterior half of concave area). Mesoscutum and scutellum faintly rugulose. Notaulus nearly linear (only very slightly sinuous). Parapsidal furrow present as obscure line. Tegula light brown. Metapleuron areolate. Mesosternum rugose laterally, irregularly areolate medially. Propodeum long, greater or equal than half length of petiole; dorsally without areolate to rugulose sculpture, laterally nitid; propodeal area ventral to petiole flat. Propodeum dorsally rugose; lateral and posterior faces of propodeum alveolate-areolate. Legs covered with long setae, uniformly brown except fore leg tibia and tarsus light brown. Hind coxae punctuate-rugulose. Hind and mid trochanters, femora, and tibiae punctuate-perlate.

Fore wing with 7 cells enclosed by tubular veins. 2Mb, 3M, and 3CU veins spectral. 1RS vein attached to Sc+R at stigmal vein. Hind wing with 4 hamuli; proximal hamulus separate from the others and more erect. One specimen (DERV099a) with teratological wing vein deformations (see Mani & Muzaffer (1944) for examples observed in Evania appendigaster (L.)).

Gaster elliptical, much less than half the size of the mesosoma in lateral view. Petiole >6 times longer than width, even wide along its length, rugose laterally, rugulose dorsally and ventrally, and with long setae.

Ovipositor straight, as long as petiole (i.e., slightly longer than in A. gattiae) concealed within metasoma.

The specific epithet is a combination of longus (Latin meaning, “long”) and saeta (Latin meaning, “setae”). The name is feminine.

Unknown.

Female description: As for male except: eye strongly elliptical, smaller, flatter. Gena nitid.Vertex not obviously distinguished by sculpture. Scape, pedicel light brown to yellow. Flagellum brown. Notauli sinuous. Mesopleuron ventrally alveolate, irregularly areolate medially (in median depression), nitid dorsal to the median depression; antero-dorsal corner of propodeum punctate. Propodeum laterally with large nitid to slightly rugulose areas; alveolate dorsal of those areas and on posterior face of the propodeum ventral to the articulation with the petiole. Petiole with irregular, parallel rugae dorsally.
