Astata rufoatra sp. nov.

Holotype.

Namibia • ♂; Khomas pr., 25 km NEE Vsakos [recte Usakos]; 21°52'S, 15°19'E; 1110 m alt.; 17.3.2014; J. Halada leg.; OLML.

Diagnosis male.

Astata rufoatra sp. nov. is a member of the A. miegii group with setose dorsal surface of propodeum. From the other species of this group ( A. gracilicornis , A. melanaria and A. lubricata ), it is distinguished by the red and black metasoma, by limitation of dorsal surface of propodeum by a foveate carina and a granulate structure of the lateral surface of propodeum before and behind the propodeal spiracle.

Description male.

Habitus. Dorsal Fig. 32 , lateral Fig. 33 . Body length 11 mm. Head. Black. Mandible black, with black bristles and distinct basal lobe. Clypeus shiny, with scattered fine punctures, middle lobe produced into an obtuse point (Fig. 35 ). Face and frons very closely punctate with appressed white pubescence (Fig. 34 ). Occiput shiny, with shallow punctures and erect white setae. Antenna. Black. Antennomere III about 3.5 × as long as II, 1.6 × longer than IV. Middle segments of antenna moderately convex in profile, with carinate tyloids, the latter without pale tubercles (Fig. 36 ). Thorax. Black, with scattered erect whitish pubescence. Pronotal lobe black. Tegula pale yellow. Pronotum closely and finely reticulate. Mesoscutum shiny, strongly and irregularly punctate, proximally closer and finer than distally, lateral surface dull with very dense punctures. Mesoscutellum in anterior half smooth and shiny with isolated punctures, in posterior half and laterally very densely punctate. Mesopleuron dull, closely and deeply punctate, posterior coarsely reticulate. Wings. Basal sclerite pale yellow. Forewing hyaline, faintly obscured in area of venation, veins and pterostigma dark brown. Marginal cell about 4.3 × as long as maximally wide. Legs. Black, with scattered erect whitish pubescence, foretibia with pale yellow basal spot. Propodeum. Black. Dorsal surface with whitish setae, reticulate, laterally limited by a distinct row of foveolae. Posterior surface irregular reticulate with long white setae. Lateral surface with different structure; anteroventrally reticulate, area before and behind propodeal spiracle granulate. Metasoma. Terga I-III and sterna II-III red, proximal segments black. Terga II-VI with pale brownish apical margins. Terga with microsculpture, tergum I with shallow punctures, V-VI with some strong punctures, VII dull with coarse punctures basally. Tergum I and sterna with white setae. Sterna III-VII without hairbrush, but with coarse and deep punctures, scattered on III-IV, dense on V-VII.

Female unknown.
