cupreolus Barbosa & Azevedo, species-group nov. (Figs 16, 17, 18A–F) Females. Mandible with five distal teeth, evenly developed; clypeus short; antennal scrobe carinate; frons projected anterad; frontal angle of ocellar triangle acute or about right; ocelli small; vertex convex. Pronotum without transverse pronotal carina; parapsidal signum with anterior half continuous; metapectal-propodeal disc with anterior margin of propodeal declivity not setose; mesopleuron with lower mesopleural fovea opened, mesopleural suture opened. Forewing bi-banded, and with R1 vein indistinct. Mesotibia not spinose Metatrochanter with lateral expansion. Metasoma with distal spiracle of metasoma large. Posterior hypopygeal margin projected convex. Genitalia with 2vv as long as 1vv, and apex slender; sting (1vv+2vv) long [surpassing 3vv apex]; 1vf strongly curved upward; 1rv not curved, with 1rv ventral process small, and posterior process short. Males. Frons coriaceous, with metallic reflexion. Clypeus short; median clypeal carina as high as epistomal suture, in lateral view; antenna not elongate; antennal scrobe ecarinate. Pronotal disc with transverse carina incomplete. Metapostnotum with first pair of metapostnotal carina and metapostnotal-propodeal suture convergence absent; propodeal declivity with sculpture present. Mesopleuron with lower mesopleural fovea opened and mesopleural suture closed. Forewing with Cu vein distinct of cu-a and R-rs&Rs vein distinct. Hind wing with two proximal and five distal hamuli. Posterior hypopygeal margin notched. Genitalia with paramere longer than basiparamere; inner margin of basivolsella straight. Distribution. It is mostly from Neotropical region. Remarks: This new species-group is easily recognized by having the “head long”, “eye large”, “frons projected anterad”, and “forewing bi-banded". Members of this species were formerly placed together in the pulchripennis species-group by Evans (1965), but A. pulchripennis does not match these characteristics. Thus we propose to reallocate A. pulchripennis to the megacephalus species-group and propose cupreolus as new name for this species-group. This species-group is composed of 23 species (Table 1).
