guianae Barbosa & Azevedo , species-group nov.

( Figs 20C–D, 20F, 20H–M )

Females. Head longer than wide; mandible with five distal teeth, evenly developed; clypeus short; antennal scrobe carinate; frontal angle of ocellar triangle acute or right; ocelli small; vertex convex. Pronotal disc with transverse carina incomplete; parapsidal signum with anterior half continuous. Metapectal-propodeal disc longer than wide; anterior margin of propodeal declivity not setose; mesopleuron with mesopleural and lower foveae, and mesopleural suture opened. Forewing with R1 vein indistinct. Mesotibia not spinose. Metatrochanter with lateral expansion. Metasoma with distal spiracle of metasoma small. 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. Unknown

Distribution. This group is restricted to Neotropical region.

Remarks. This new species-group is defined mainly by having the body and metapectal-propodeal disc conspicuously elongate. A few other species of Anisepyris can have the “head longer than wide” and “metapectalpropodeal disc longer than wide”. Members of this group, however, additionally have the “mesopleural fovea opened” and “sting (1vv+2vv) long [surpassing 3vv apex]”, this characteristic combination was observed only for these species. Therefore, from this characteristic combination, we propose this new species-group under the name guianae . This species-group is composed of four species ( Table 1).
