Anisepyris dietrichorum


dietrichorum Barbosa & Azevedo  , species-group nov.

( Figs 18G –NView FIGURE 18, 19A –FView FIGURE19)

Females. Head longer than wide; mandible with five distal teeth, evenly developed; clypeus short; antennal scrobe ecarinate; frontal angle of ocellar triangle about right; ocelli very small; vertex straight. 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. Mesotibia not spinose Metatrochanter with lateral expansion.

Males. Frons coriaceous  or weakly 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 complete. Metapostnotum with first pair of metapostnotal carina and metapostnotal-propodeal suture convergence absent or present; propodeal declivity with sculpture present; distinction between metapectalpropodeal disc and metapleuron distinct by sculpture difference. Mesopleuron with lower mesopleural fovea opened and mesopleural suture closed. Forewing with Cu vein indistinct of cu-a and R-rs&Rs vein distinct. Hind wing with one or two proximal and four distal hamuli. Posterior hypopygeal margin uniform. Genitalia with paramere as long as or longer than basiparamere; inner margin of basivolsella straight.

Distribution. It is mostly from Neotropical region

Remarks. In this species-group we found a peculiar and rare characteristic among Anisepyris  species: the “distinction between propodeum and metapleuron with distinct texture”. This is rare in Anisepyris  and in Epyrinae  as a whole, but is common in Mesitiinae  , as cited by Barbosa & Azevedo (2011). Therefore, we reallocate these species from the proteus  species-group into a new species-group under the name dietrichorum  . This species-group is composed of 10 species ( Table 1).
