Anisepyris aeneus


aeneus  species-group

( Figs 3View FIGURE 3, 4View FIGURE 4, 5View FIGURE 5, 6A –CView FIGURE6)

Females. Mandible with five distal teeth, and evenly developed; antennal scrobe ecarinate; frontal angle of ocellar triangle about right; ocelli very small; vertex straight or concave. Pronotal disc with transverse carina incomplete; anteromesoscutum with parapsidal signum with anterior half not continuous; mesopleuron with lower mesopleural fovea opened, mesopleural suture opened, and posterior mesopleural sulcus present. Forewing with R1 vein distinct. Mesotibia spinose. Metatrochanter without lateral expansion. Posterior hypopygeal margin convex. Genitalia with 2vv as long as 1vv, and abruptly slender; sting (1vv+2vv) long, surpassing 3vv apex.; 1vf strongly curved upward; 1rv strongly curved, with 1rv ventral process small, and posterior process long.

Males. Frons not or weakly coriaceous  , with metallic reflexion. Clypeus long; median clypeal carina as high as epistomal suture, in lateral view; antennal scrobe ecarinate. Pronotum without transverse pronotal carina. Metapostnotum with first pair of metapostnotal carina and metapostnotal-propodeal suture convergence absent; propodeal declivity sculptured. Mesopleuron with lower mesopleural fovea and mesopleural suture opened. Forewing with Cu vein distinct of cu-a and R-rs&Rs vein distinct. Hind wing two proximal and four distal hamuli. Posterior hypopygeal margin convex. Genitalia with paramere as long as basiparamere; inner margin of basivolsella straight.

Distribution. Neotropical region with a few nearctic species.

Remarks. Evans (1966) defined this group based on the following characteristics: the mandible with five distal teeth; the antennal scrobe carina absent; the transverse pronotal carina incomplete; the mesopleuron with the lower fovea opened; and the mesotibia with distal spines. The aurichalceus  species-group shares some of these characteristics, but differs in having the antennal scrobe carina weakly impressed and the transverse pronotal carina complete; in the aeneus  species-group these chacteristics are well impressed and incomplete, respectively. Thus, distinguishing the aeneus  and aurichalceus  species-groups became impossiblebecause most of the characters used to define them are present in both groups. Therefore, we fused these species-groups under the name aeneus  . The species-group contains 31 species ( Table 1).
