Redescription. FEMALE (holotype). Body mostly dark brown except base of gaster yellow to light brown, hypopygium brown, midlobe of mesoscutum with a light brown transverse submedian stripe, and borders of axilla and dorsellum light brown. Appendages light brown to brown.

Vertex transversely striate, with a few short setae.

Antenna ( Fig. 84 ) with short setae. Pedicel much longer than F1; all funicular segments at least a little longer than wide; F1 the shortest funicular segment, F2–F5 gradually slightly increasing in length and each much shorter than F6; F1–F5 without longitudinal sensilla, F6 with 2 longitudinal sensilla; clava about 4.0 x as long as wide, with 5 longitudinal sensilla.

Mesosoma ( Fig. 85 ). Mesoscutum wider than long, its midlobe finely longitudinally striate and with 1 pair of strong setae. Scutellum about as long as mesoscutum, posterior scutellum finely longitudinally striate. Dorsellum broadly angulate posteriorly.

Wings. Forewing ( Fig. 86 ) 4.7 x as long as wide; blade slightly infumate behind venation but otherwise hyaline, with a few setae only in the apical 1/4; longest marginal cilia about 1.2 x greatest width of wing. Hind wing 16 x as long as wide, almost as long as forewing; blade slightly infumate apically; longest marginal cilia about 3.7 x greatest wing width.

Metasoma ( Fig. 85 ). Petiole wider than long. Gaster longer than mesosoma; ovipositor about 4/5 length of gaster, exserted beyond apical gastral tergum by about 1/5 of ovipositor length and a little exserted beyond apex of hypopygium, 1.6 x length of metatibia.

Measurements of holotype (in µm). Body 670; mesosoma 258; gaster 345; ovipositor 273. Antenna: scape (including radicle) 112; pedicel 42; F1 17; F2 18; F3 21; F4 24; F5 27; F6 52; clava 124. Forewing 484:104; longest marginal cilia 124. Hind wing 479:30; longest marginal cilia 112. MALE. Unknown. Diagnosis. Member of the flavovarius species group. Erythmelus (E.) cingulatus is extremely similar to E. (E.) pastoralis Ogloblin , which has a relatively shorter ovipositor (ovipositor length: metatibia length ratio 1.4:1); the minor differences between these two species are indicated in the key above. Distribution. Argentina. Hosts. Unknown.
