Stenonartonia cooperi Garcete-Barrett, sp. nov.

Stenonartonia cooperi Garcete-Barrett, sp. nov. (Figs 2, 3, 8, 14, 27, 56, 60, 69, 82, 100, 114, 138, 141, 152, 163, 171, 176, 177, 178) Nortonia polybioides (nec von Schulthess 1904): Ducke 1910: 187. Diagnosis and comments. This species differs from S. polybioides and S. hasyva by the absence of an anterolateral scutellar “window” and by having: lateral axillary panel produced mesoposteriorly in a tongue-like projection; metanotum strongly angular in side view; the propodeal striation strong, longitudinal below and visibly mixed with coarse macropunctation above; clypeal apex slightly but definitely emarginated; apical propodeal lamella projecting upward; T 1 wide campanulate; male mid femur just slightly concave ventrally near its base and the antennal hook of the male simple and reduced. Description. FEMALE. Differing from S. polybioides in: Color pattern. Supraocular marking detached from the eye, elongated, touching the postocellar marking and with an additional arm extending to the occipital band. Occipital band reduced and with its anterior arm detached. Mesonotal yellow lines curving outward in front. Tegula with a blackish inner border. Axilla and lateral axillary panel black. Sublateral propodeal marking in the shape of a large black triangle with a small anterior yellow dot. Dark areas on mid and hind legs darker and sharper. Measurements and proportions. Body length 12 mm. Wing length 13.1 mm. Clypeus 1.19 × wider than high and with its apical margin 1.1 × wider than the interantennal distance. T 1 1.16 × longer than wide and 0.63 × as wide as T 2. S 1 campaniform, with slightly curved sides: 1.63 × wider than its medial length and 1.22 × wider than its total length. Structure. Clypeus with a small translucent semicircular apical depression and with its apical margin slightly concave. Interantennal carina slightly sharper. Parategula digitiform. Scutellum more convex and without anterolateral “window”. Axilla broader. Lateral axillary panel elongate tongue-like produced posteromesally, partly overlapping the posterior tip of the axilla and reaching the scutellar border. Metanotum acutely projecting in lateral view, with a well marked toothed ridge. Posterior metapleural border not marked. Propodeum more convex. Mid propodeal carina higher. Submedial propodeal carina higher and lamellar, translucent. Apical propodeal lamella expanded and angularly projected upward in lateral view. T 1 broad campaniform, with a stronger transverse carina curving backward at the level of the spiracle, with a broader transverse sulcus and with the longitudinal sulcus a little wider but a bit shallower and continuing for short in front of the transverse carina. Tegumental sculpture. Specialized area of the vertex split in two. Scutellar and mesepisternal macropunctures coarser and separated by less than their own diameter. Metanotum coarsely macropunctured and with a well defined anterior band. Metapleura with indications of thin sparse macropunctures. Propodeal side with moderately abundant macropunctures. Sublateral propodeal surface covered with strong striae which are diagonal just above, turn longitudinal below, do not reach the medial channel and is mixed with coarse macropunctation which is especially evident anteromesally. S 1 with a very thin medial carina and covered with irregular and shallow striatopunctation which is transverse at the base and become longitudinal shortly behind. Metasomal punctation coarser and more sharply defined. Pilosity. Thinner and shorter, except for the propodeum, which bears longer hairs. MALE. Differing from the female in: Color pattern. Discussed under variation. Measurements and proportions. Body length 10.6 mm. Wing length 12.3 mm. Clypeus 1.04 × wider than high and with its apical margin 1.3 × wider than the interantennal distance. Structure and tegumental sculpture. General body shape not especially delicate neither the head especially smaller than in the female. Clypeus with a deeper apical emargination. F 9 cylindrical. F 11 short, finger-like, slightly tapering apically. Mesepisternal macropunctation denser. Mid femur rather normal, with just a slight basal depression ventrally. Propodeum as convex as in the female. Propodeum with thinner striae wish are almost striatopunctures above. Variation. The color pattern described above is typical of the Colombian specimens. There is some variation in the extent of the black markings: The postocellar marking can touch the occipital band so there can be a black preoccipital area with a pair of large yellow dots inside. The occipital band is almost absent in the male from Santarém. The humeral line can be large or reduce to a small dot. The axillar region can be largely yellow. The metanotum may have the dark areas quite reduced. The mid propodeal carina can be either black or yellow. The extent of the sublateral propodeal marking is the most geographically related variation: It is very large in individuals from the upper Amazon (Colombia, Peru, and Ecuador), to the point that the specimens from Mocoa have the propodeal declivity black with just a couple of thin submedial yellow lines. The specimen from Rondônia has the marking as in S. polybioides. The specimens from Guianas, Tumucumaque and Bragança have it split in a short postspiracular line and a small submedial dot. The specimens from Santarém and Óbidos have no sublateral markings. Biology. The specimens from La Macarena and La Chorrera were collected, and some of them labeled as emerged from, in association with two nests now deposited in the BMNH and referred with notebook numbers 147 and 99 by Martin Cooper. They were built on the underface of a leaf and are made of reddish to yellowish clay. The nest from La Chorrera is better preserved and has three more or less rectangularly shaped cells placed in a slanted pattern. The nest from La Macarena is mostly destroyed, but seems like it has a similar structure. Almost all of the specimens carry acari in their axillary fossa openings. A mite is even visible through the translucent cuticle of the inner lamella of the scutellar crest in one of the specimens from Surinam. Type material.

This species is dedicated to Martin Cooper, a well known wasp collector and vespid taxonomist. Antonio Giordani Soika labeled several specimens with this name but never described the species.Published as part of Garcete-Barrett, Bolívar R., 2011, A revision of the genus Stenonartonia Giordani Soika 1973 (Hymenoptera: Vespidae: Eumeninae), pp. 1-50 in Zootaxa 2868 on pages 13-15, DOI: 10.5281/zenodo.27749
