Fiorianteon sulcatum sp. n. is described from Fianarantsoa Province (Madagascar). It is the first species of Fiorianteon found in the Afrotropical region. The genus Fiorianteon can be distinguished from the closely related genus Conganteon by the distal part of the stigmal vein, which is as long as, or shorter than the proximal part of the stigmal vein (longer than the proximal part of the vein in Conganteon).
Taxonomy, Fiorianteon sulcatum , Madagascar, Conganteoninae , Chrysidoidea
Dryinidae (HymenopteraChrysidoidea) are parasitoids of Hemiptera, Auchenorrhyncha (
The genus Fiorianteon Olmi, 1984 (Conganteoninae) is only present in the Oriental and Eastern Palaearctic zoogeographical regions (
The genus was originally revised at world level by
In 2015, we examined additional specimens of Dryinidae from Madagascar, which included the new species of Fiorianteon described in this paper.
The descriptions follow the terminology used by
The multifocal pictures were taken by a stereomicroscope Leica M205A and Leica DFC450 video camera, captured using Leica Application Suite v. 4.2.0.
Fiorianteon Olmi, 1984: 108. Type species: Fiorianteon junonium Olmi, 1984, by original designation.
Female: fully winged; occipital carina complete; mandible quadridentate, with one intermediate rudimentary tooth; antenna without rhinaria; palpal formula 6/3; pronotal tubercles present; forewing with two cells enclosed by pigmented veins (costal and median); forewing with stigmal vein and pterostigma present; distal part of stigmal vein as long as, or shorter than proximal part of stigmal vein; protarsus chelate; chela with rudimentary claw; tibial spurs 1/1/2. Male: fully winged; occipital carina complete; mandible quadridentate, with one intermediate rudimentary tooth; palpal formula 6/3; forewing with two cells enclosed by pigmented veins (costal and median; fore wing with stigmal vein and pterostigma present; distal part of stigmal vein as long as, or shorter than proximal part of stigmal vein; tibial spurs 1/1/2.

The two main characters distinguishing the new species are detailed in the above diagnosis. These characters are not present in any of the known species of Conganteoninae (
The species is named sulcatum because the head is sculptured by many longitudinal subparallel keels.
