P a r a t y p e s (2 and 1): same data (ZSM and Coll Riedel).  
D e s c r i p t i o n of: Body length 9-9.5 mm. Flagellum lanceolate, with 33 flagellomeres, first flagellomere (without anellus) 3.2x as long as wide, both basal flagellomeres together about 0.74x as long as compound eye, about 11th or 12th flagellomere square, widest flagellomeres 1.5x as wide as long. Temple short, strongly narrowed behind eye, with superficial puncture. Distance of lateral ocellus to compound eye about 1.2x its diameter. Frons smooth, above with superficial puncture. Face and clypeus with puncture, intervals smooth. Genal carina meets the hypostomal one close to mandibular base.  
Mesosoma with short whitish hairs. Notaulus not impressed. Mesoscutum with coarse puncture and granulation, matte. Mesopleurum densely punctured, speculum smooth. Metapleurum with dense puncture. Coxal carina distinct. Scutellum moderately convex, wider than long, with strong lateral carina in the basal 0.7 and scattered puncture. Propodeum with coarse puncture, shining. Areae basalis and superomedia confluent and smooth. Coxa III with dense puncture, without scopa. Femur III with dense puncture, about 4.2x as long as high.  
Areolet pentagonal, frontal distance of intercubiti 2x its diameter, nervulus slightly postfurcal.  
Postpetiole slightly widened. Median field with very fine striation. Gastrocoelus small, impressed. Thyridium very small, about 0.2x as wide as the thyridial interval. Second tergite as long as wide. Tergites 2-3 with dense puncture, tergite 2 with fine median striation in the basal 2/3. Tergite 4 with superficial puncture. Ovipositor sheath long, seen from dorsal 1.5x as long as the seventh tergite.  
Coloration: black. Cream-yellow are stripe on flagellomeres 8-12, palps, labrum, clypeus and face, gena and complete orbit, anterior and upper margins of pronotum, subtegular ridge, longitudinal stripe on lower mesopleurum, sides of scutellum, postscutellum, carinal triangle, small spot on posterior propodeum at dentiparal edge, coxae I-II, trochanters I-III, anterodorsal spot on coxa III. Coxa III red ventrally, with black apical mark dorsally. Legs otherwise yellowish-red. Femur III red, infuscate in the apical 0.2. Tibia III dark reddish, infuscate in the apical 0.3, tarsus III blackish. Postpetiolus with yellow posterodorsal spot, tergite 2 with a wide yellowish apical band, tergite 3 with a more diffuse reddish-yellow hind margin. Tergite 6 with a yellowish apical band, tergite 7 mainly yellow. Pterostigma brownish.  
D e s c r i p t i o n of: Body length 8 mm. Flagellum with 30 flagellomeres, first flagellomere 2.5x as long as wide. Linear tyloids on flagellomeres 9-14. Femur III 4.2x as long as high. Metapleurum with superficial and scattered puncture. Structure otherwise as in.  
Coloration: as described for the except an cream-yellow spot on scapus beneath, and a narrow black interruption of orbit between frontal and vertical orbits. Tergite 2 with a reddish-yellow apical band, tergites 3-4 with diffus reddish-brown apical bands.
