Aiura , a new genus of Campopleginae ( Hymenoptera ; iCHneumonidae ) from Brazil onody

Aiura, a new genus of Campopleginae (Hymenoptera; ichneumonidae) and the species A. miri and A. turu are described from Campos do Jordão, sp, Brazil.

amongst material collected during the project "diversity of Braconidae (Hymenoptera) fauna at different altitudes in Campos do Jordão, são paulo, Brazil" eight specimens were found, which are called Aiura, a new genus.
the specimens were collected in the atlantic forest (22° 44' s and 45° 30' w) at high altitudes, occurring above 1100 m.
Aiura runs to couplet 41 in townes key (1970) for the Campopleginae genera.it is, however, different from Tranosema foerster, 1869 and Diadegma foerster, 1869 by having mesopleurum coriaceous; propodeum long, posteriorly produced into a "neck"; metasoma strongly compressed and elongated; tergite ii long, thyridium separated from the base by about 4.0-5.0times its length; tergites iii and the following ones posteriorly incised mid-dorsally; ovipositor very stout, compressed laterally and up curved.
the terminology in this study follows townes (1969,1970).the type of material is deposited in the dCBu collection (departamento de ecologia e Biologia evolutiva, ufsCar, são Carlos, sp, Brazil).
Etymology: the genus name derives from the tupy language (Aiúra = "neck"), with reference to the shape of the propodeum produced into a "neck".
first segment with suture between tergite and sternite ventral, deep glymma in front of spiracle; second tergite long with subcircular thyridium separated from base of tergite by about 5 times its length.ovipositor stout, strongly up curved, about 2 times as long as apical depth of abdomen.
Male: similar to female, but propleural flange entirely black, hind femur basally and distally less infuscate, and hind tibia basally not yellow.antenna, with 37 flagellomeres; scape and pedicel are entirely black.
Biology: unknown.Etymology: the species name derives from the tupy language (Turú = big) with reference to the dimensions of the specimens.
