Diagnosis and comments. This species is distinct in the group of S. polybioides by having the propodeal striae almost transverse, very weak, obscured by dense macropunctation and also: transverse carina of T1 weak; overall pilosity very sparse and short; metasomal macropunctation coarser and deeper and dark areas of the metasoma dark brown. As in S. cooperi there are no scutellar “windows”, but the metanotum is not so prominent in profile and the lateral axillary panel is less produced backwards.

Description. FEMALE. Differing from S. polybioides in: Color pattern. Scape black dorsally. Flagellum brown dorsally. Black markings of the head wholly interconnected as in the darker headed specimens of S. cooperi , but with the frontal mark briefly interrupted midway to the antennal socket. Humeral line shaped like a baseball bat. Mesoscutum with an additional lateral yellow line. Medial line of scutellum thinner. Metanotum entirely yellow. Propodeum yellow, with only the medial channel and a subtle sublateral spot darkened. Legs without dark markings. T1 extensively yellowish on its anterior half; metasomal terga with the dark areas darker brown, partly blackish. S2 with some basal darkening. Fore wing venation brown, a bit lighter along the costal region.

Measurements and proportions. Body length 12.6 mm. Wing length 11.3 mm. Clypeus 1.28 × wider than high and with its apical margin as wide as the interantennal distance. T1 1.21 × longer than wide and 0.67 × as wide as T2. S1 campaniform, with slightly curved sides: 1.8 × wider than its medial length and 1.27 × wider than its total length.

Structure. Clypeus slightly more convex and with its apical margin definitely concave. Pronotal carina more weakly emarginated below the humeral angle. Parapsidal line undistinguishable. Parategula hook-shaped. Axilla broader. Lateral axillary panel shortly tongue like produced posteromesally, hardly overlapping the posterior tip of the axilla and not reaching the scutellar border. Scutellum slightly more convex and without anterolateral “window”. Metanotum right angled in profile, with a well marked toothed ridge. Posterior metapleural border not marked. Propodeum strongly convex and with a very narrow medial channel. Apical propodeal lamella expanded and slightly angular upward in lateral view. T1 broadly campaniform, with a weak transverse carina which is slightly retuse forward and shortly interrupted at the middle and hardly reaches the level of the spiracle, with a very superficial longitudinal sulcus and without transverse sulcus.

Tegumental sculpture. Clypeus covered with a well marked but shallow macropunctation over its upper quarter. Pronotum coarsely macropunctate, even on its lateral surface. Scutellar macropunctures coarser and separated by less than their own diameter. Metanotum covered with coarse, almost confluent macropunctures and with a well marked anterior band. Mesepisternal macropunctures abundant, separated amongst them by 0.5 to 1 diameter. Metapleura and propodeal side with some thin scattered macropunctures. Sublateral propodeal surface covered with dense and shallow macropunctation obscuring a very thin, weak and almost transverse striation that does not reach the medial channel. Disc of T1 with well defined macropunctation. S1 covered with coarse and dense macropunctation. T2 covered with well defined and moderately spaced macropunctures which turn much denser and coarse on the apical yellow band.

Pilosity. Overall pilosity shorter and less evident. Inner lamella of the scutellar crest covered with long appressed hairs pointing toward the opening of the axillary fossa and partly obscuring it.

MALE. Unknown.
