Anisepyris bifidus Barbosa & Azevedo

bifidus Barbosa & Azevedo, species-group nov.

(Figs 9G–O, 10A–I)

Females. Head as long as wide; mandible with five distal teeth, evenly developed; clypeus long; antennal scrobe ecarinate; frontal angle of ocellar triangle about right; ocelli small; vertex convex. Pronotal disc with transverse carina complete; parapsidal signum with anterior half continuous; metapectal-propodeal disc as long as wide; anterior margin of propodeal declivity not setose; mesopleuron with mesopleural fovea closed, lower fovea and mesopleural suture opened, and posterior mesopleural sulcus absent. Mesotibia not spinose. Metatrochanter with lateral expansion.

Males. Frons coriaceous, with metallic reflexion. Clypeus short or long; median clypeal carina as high as epistomal suture, in lateral view; antenna not elongate; antennal scrobe ecarinate. Pronotal disc with transverse carina complete. Metapostnotum with first pair of metapostnotal carina and metapostnotal-propodeal suture convergence absent; propodeal declivity with sculpture present. Mesopleuron with lower mesopleural fovea and mesopleural suture opened. Forewing with Cu vein indistinct of cu-a and R-rs&Rs vein distinct. Hind wing with two proximal and four distal hamuli. Posterior hypopygeal margin convex. Genitalia with paramere bifid and longer than basiparamere; inner margin of basivolsella straight.

Distribution. It is restricted to Neotropical region.

Remarks. This new species-group has a peculiar characteristic among Anisepyris species. Their males have the genitalia with the “paramere bifid”, which was commonly observed in some species from the proteus speciesgroup. Additionally, we observed some other characteristics shared between these formerly cited species, so we concluded that all species with this genitalic characteristic could be grouped together, separate from the proteus species-group. Using the traits discussed above, we diagnosed bifidus, and composed the group to include six former members of the proteus species-group and seven new species. This species-group is composed of 13 species (Table 1).
