Diagnosis

Synosis cosnipatensis is easily distinguished by the combinations of characters hind coxa reddish and submetapleural carina anteriorly expanded into conspicuous triangular lobe.

Description

Female. Total length 4.8–5.3 mm; fore wing length 3.8–3.9 mm. Head punctate; antenna with 30–32 flagellomeres, first flagellomere 2.2–2.3× as long as centrally broad, and subapical ones elongate c.1.2–1.3× as long as centrally broad; lateral ocellus separated from compound eye by 1.0–1.2× ocellar diameter; face c.0.85× as wide as long, coarsely punctate; mandibles not twisted, slightly tapered with the upper tooth broader and 1.7–2.0× longer than lower tooth; malar space 1.1–1.2× as long as basal mandibular width; gena, in lateral view, 0.75–0.88× as long as compound eyes. Mesosoma generally with punctures except for the pronotum polished, with band of setae along the upper and posterior margin, elsewhere bare and speculum and the area below bare; notauli extending to centre; epomia strong, almost reaching upper margin of pronotum; mesoscuto-mesoscutellar groove deep, wide and smooth; scutellum with longitudinal lateral carinae reaching to apex; metapleuron polished, with a band of hairs along its upper margin, elsewhere bare; submetapleural carina anteriorly expanded into conspicuous triangular lobe. Propodeum with lateromedian longitudinal carinae anteriorly converging and in contact, area basalis and superomedia smooth with few punctures, anterior carina transverse absent between longitudinal carinae. Fore wing with abscissa of Cul between 1m-cu and Cu1a 1.6–1.8× as long as Culb; cu-a postfurcal. Metasoma with tergite I moderately slender, 1.1–1.2× as long as posteriorly broad, lateromedian carinae c.0.3× length of tergite, in dorsal view coarsely punctate, except between the lateromedian carinae; tergite II coarsely punctate, except the hairless anterior central area, c.0.8× as long as posteriorly broad; tergite III–VI punctate. Laterotergites I and II developed, laterotergite II 0.4–0.5× wide as long.

Head black except extensively yellow on the face, malar space, frons on the inner orbit, palpi, ventral part of scape, and mandibles. Mesosoma predominantly black, except for tegula, upper part of subalar prominence and apical part of the prosternum yellowish. Metasoma black. Legs reddish. Wings hyaline; pterostigma brown.

Male. Unknown.

Etymology

The specific epithet is based on the type locality, the Cosñipata Valley.
