A new species of Anteon Jurine, 1807 is described from Laos, Houaphanh Province: A. holzschuhi sp. n. Morphologically the new species is similar to A. semipolitum Olmi, 2008, but it is distinguished by the sculpture of the face partly reticulate rugose and partly with deep punctures similar to areolae; in A. semipolitum the face is completely punctate and unsculptured among punctures. In addition, in the new species the distance from the outer edge of a lateral ocellus to the compound eye (OOL) is about 3.3 times as long as the distance between the inner edges of a lateral ocellus and the median ocellus (OL); in A. semipolitumOOL is less than twice as long as OL. Published identification keys to the Oriental species of Anteon are modified to include the new species.
Taxonomy, Anteon holzschuhi , Oriental region, key, Houaphanh Province, Anteoninae
Dryinidae (Hymenoptera, Chrysidoidea) are parasitoids of leafhoppers, planthoppers and treehoppers (Hemiptera, Auchenorrhyncha) (
The species of Anteon inhabiting the Oriental region were studied by
Anteon species are parasitoids of leafhoppers belonging to the Cicadellidae (
In 2015 we examined additional specimens of Anteon from Laos and discovered a new species described in this paper.
The descriptions follow the terminology used by
The types of all Oriental species of Anteon have been previously examined by the authors.
The type specimen described in this paper is deposited in the collection of the Oberösterreichisches Landesmuseum, Linz, Austria (OLL).
The description of the new species is based on the study of a single specimen. The authors are aware that descriptions of new taxa should normally be based on more individuals. However, Dryinidae are so rare that it is uncommon to collect more than one specimen of each species. In addition, on the basis of the experience and knowledge of the authors, the new species is sufficiently delimited by unique characters to justify its description.
Anteon Jurine, 1807: 302. Type species: Anteon jurineanum Latreille, 1809, by subsequent monotypy.
Female: Fully winged; rarely brachypterous; occipital carina complete; palpal formula 6/3; antenna without rhinaria; forewing with three cells enclosed by pigmented veins (costal, median and submedian); forewing with stigmal vein and pterostigma; distal part of stigmal vein much shorter than proximal part, occasionally slightly shorter, as long as, or longer than proximal part; propodeum usually with transverse keel between dorsal and posterior surface; protarsus chelate; inner side of enlarged claw with proximal prominence bearing one long bristle; tibial spurs 1/1/2. Male: Fully winged; rarely brachypterous; occipital carina complete; vertex of head usually without two oblique keels connecting posterior ocelli to occipital carina; palpal formula 6/3; forewing with three cells enclosed by pigmented veins (costal, median and submedian); forewing with stigmal vein and pterostigma; distal part of stigmal vein much shorter than proximal part, occasionally slightly shorter, as long as, or longer than proximal part; pterostigma less than four times as long as broad; propodeum usually with transverse keel between dorsal and posterior surface; paramere usually without inner branch wrapping penis; tibial spurs 1/1/2.
Male with antenna filiform; face partly reticulate rugose and partly sculptured by deep punctures similar to areolae (Fig.

The species is named after the collector, Mr Carolus Holzschuh (Villach, Austria).
The new species is similar to A. semipolitum Olmi, 2008, by having the antenna filiform, notauli reaching about 0.8 × length of scutum (Fig.
