Diagnosis

Synosis townesi may be distinguished by the lateromedian longitudinal carinae separated and submetapleural carina anteriorly expanded into a conspicuous triangular lobe.

Description

Female. Total length 5.9–6.2 mm; fore wing length 4.8–5.2 mm. Head punctate; antenna with 36–37 flagellomeres, first flagellomere c.2.8× as long as centrally broad, and subapical ones elongate c. 1.8–2.0× as long as centrally broad, clearly longer than broad; lateral ocellus separated from compound eye by c.0.85× ocellar diameter; face 0.83–0.91× as wide as long; mandibles not twisted, slightly tapered, with upper tooth broader and 1.8–2.0× longer than lower tooth; malar space 1.6–1.7× as long as basal mandibular width; gena, in lateral view, c.0.55–0.67× as long as eyes. Mesosoma generally with punctures, except for pronotum polished, with a band of hair along the upper and posterior margin, elsewhere bare and speculum and area below bare; notauli extending to centre; epomia strong, almost reaching upper margin of pronotum; scuto-scutellar groove deep, wide and scrobiculate; scutellum with longitudinal lateral carinae reaching to posterior end; metapleuron polished, with a band of hairs along its upper margin, elsewhere bare; submetapleural carina anteriorly expanded into a conspicuous triangular lobe. Propodeum with lateromedian longitudinal carinae anteriorly converging but never in contact, with a space between them wider than thickness of the two, area basalis and superomedia hairless; carina anterior transverse present between longitudinal carinae. Fore wing with abscissa of Cul between 1m-cu and Cu1a c.2.0–2.1× as long as Culb; cu-a postfurcal. Metasoma with tergite I moderately slender, 1.3–1.4× as long as posteriorly broad, lateromedian carinae c.0.3× the length of tergite, in dorsal view finally punctate, except between lateromedian carinae and area posterior, which is glabrous; tergite II finally punctate, 08–0.9× as long as posteriorly broad; tergite III–VI similarly sculptured. Laterotergites I and II vestigial, laterotergite II 0.13–0.17× wide as long ( Figure 7B ).

Head face, frons on the inner orbit, palpi and mandibles, malar space and from the malar space extends further back towards occiput yellow, ventral part of scape brownish and rest black. Mesosoma predominantly black, except for tegula, upper part of subalar prominence and apical part of the prosternum yellowish. Metasoma black. Legs yellowish, except for hind leg with coxa, apical part of tibia and tarsomeres black. Wings hyaline; pterostigma brown.

Male. Unknown.

Etymology

Named in honour of Dr Henry Townes.
