Diagnosis and comments. Stenonartonia guaranitica is a relatively stout bodied species with a short T1, a very transverse crescent shaped S1 and prominent apical propodeal lamella, readily dislocated from the valvula in side view. They are medium sized, grayish wasps with dull amberish wings, dark mesosoma and strongly banded mesosoma reminiscent of the social wasp Brachygastra lecheguana .
Description. FEMALE. Color pattern. Black integument with light orange yellow markings as follows: short lower inner orbit; small suffuse spot at the posterior pronotal corner; short inner line along fore femur; diffuse apical ring on mid and hind femora; anterior face of mid tibia; external line along mid and hind tibiae; suffuse lateral margin and sometimes also a medial posterior spot on T1; some suffusion on S1; thick apical bands on metasomal segments 2–6. Brown are: flagellum ventrally; mandible except for the teeth and the basal triangle; apical tarsomeres; S1 largely. Wing membrane and venation dull amberish, gradually turning into dull brown toward the apex. Measurements and proportions. Body length 9.8 mm. Wing length 9.6 mm. Clypeus 1.1 × wider than long and with its apical margin 0.9 × as wide as the interantennal distance. T1 1.36 × wider than long and 0.77 × as wide as T2. S1 very transversely crescent-shaped: 3.4 × broader than its medial length and 2.10 × broader than its total length. Structure. Clypeus cordiform, moderately convex above and gradually flatter below, with a shallow apical depression and small but marked semicircular emargination between two shortly carinate and slightly outpointing teeth. Humeral angle weak, obtuse in frontal view. Pronotal carina slightly undulated below the humeral angle. Parapsidal line vestigial. Parategula broad and short, thumb-like, almost triangular. Scutellar-axillar complex as described for S. flavotestacea . Metanotum right angled in side view and bearing a low but well defined toothed ridge. Propodeum short, semi truncate, with the lateral surface flat, the sublateral surface convex and with a diffusely defined posterior concavity where the medial channel is ill defined. Mid propodeal carina complete and sublateral propodeal carina low and lamellar. Apical propodeal lamella projected backward and separated from the valvula by both a longitudinal crease and a marginal dislocation. T1 wide campanulate, regularly convex in side view, without longitudinal carina and with a weak and straight transverse carina that hardly reaches the level of the spiracle.
Tegumental sculpture. Clypeus moderately opaque, slightly shagreened, covered with abundant micropunctation (especially on its upper half) and abundant shallow and moderately spaced macropunctation. Body surface and micropunctation as in S. apicipennins . Head and mesosomal sculpture differing from S. apicipennis in: overall macropunctation partly coarser and overall a bit sparser; tegula wholly covered with well marked and moderately dense micropunctures; metanotum with a reticularly macropunctate anterior band and with moderately dense macropunctation behind; upper metapleura bearing a series of weak and thin striae; lower metapleura and lateral propodeal surface more coarsely macropunctate; sublateral propodeal surface reticularly macropunctate and slightly striolate obliquely, especially below. T1 with a few very thin macropunctures scattered on its anterior declivity and with moderate macropunctation on its disc, coarser along its midline. S1 densely and coarsely macropunctate. T2 covered with moderately spaced macropunctation becoming gradually coarser and a little denser toward the posterior and lateral margins. Macropuncture of S2 as in T2 but specially coarser at middle. Metasomal segments 3–5 covered with moderately dense macropunctation which is a little sparser on sterna. Metasomal segment 6 with thin macropunctures obscured by the micropunctation.
Pilosity. Body covered with a grayish fulvous subappressed pubescence mixed with sparse semi erect setae. Posterior propodeal declivity with a mid lower area of downward appressed and reflective silvery pubescence. Metasomal pilosity appressed and with less evident setae.
MALE. Differing from the female in: Color pattern. Mandible mainly black, at most with a short sub-basal line. Clypeus yellow with thin black margins, at most with a short mesobasal line eventually connected to the basal margin. Scape yellow ventrally. Inner orbit reaching up to the ocular sinus. There is an interantennal spot. Antenna from F9 to the apex mostly orange brown. Metasomal segment 7 with a band across its middle.
Measurements and proportions. Body length 8.5 mm. Wing length 8.1 mm. Clypeus 1.04 × wider than high and with its apical margin 1.06 × as wide as the interantennal distance.
Structure. Clypeus more oval, with a translucent apical margin and with a deeper concavity between blunter and non-carenated teeth. F9 cylindrical. F11 short, fingerlike and a slightly tapering point. Propodeum shorter, with a more abrupt posterior declivity.
