A new species of Anteon Jurine, 1807 is described from Thailand, Nan Province: A. huettingeri sp. n. Morphologically the new species is similar to A. borneanum Olmi, 1984, A. jurineanum Latreille, 1809, A. insertum Olmi, 1991, A. yasumatsui Olmi, 1984, A. sarawaki Olmi, 1984, A. thai Olmi, 1984 and A. krombeini Olmi, 1984, but it is clearly different for the numerous sensorial processes present on the inner side of the paramere; these processes are absent in the other above species. Published identification keys to the Oriental species of Anteon are modified to include the new species.
Taxonomy, Anteon huettingeri, Oriental region, key, Nan Province, Anteoninae
Dryinidae (Hymenoptera, Chrysidoidea) are parasitoids of leafhoppers, planthoppers and treehoppers (Hemiptera, Auchenorrhyncha) (
The species of Anteon inhabiting the Oriental region have been recently studied by
Anteon species are parasitoids of leafhoppers belonging to Cicadellidae (
In 2014 we examined additional specimens of Anteon from Thailand 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 only 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 without inner branch wrapping penis; tibial spurs 1/1/2.
Male with antenna filiform; scutum very slightly granulated and finely punctate; posterior surface of propodeum without longitudinal keels; paramere without distal inner process, with inner side provided with many sensorial processes (Fig.
Male. Fully winged (Fig.
Female. Unknown.
Holotype: male, Thailand, Nan Province, outside Mae Charim National Park gate, 18°36.00'N, 100°58.34'E, 260 m, 13.v.2012, E. & J. Hüttinger leg. (OLL).

Unknown.
The species is named after the collector, Dr Ernst Hüttinger.
Because of the antenna filiform, the scutum neither rugose nor sculptured by irregular keels, the posterior surface of the propodeum without longitudinal keels, the paramere without distal inner process, the new species is similar to A. borneanum Olmi, 1984, A. insertum Olmi, 1991, A. jurineanum Latreille, 1809, A. krombeini Olmi, 1984, A. sarawaki Olmi, 1984, A. thai Olmi, 1984 and A. yasumatsui Olmi, 1984. The main difference between A. huettingeri and all other species is centered on the structure of the inner side of the paramere (with many sensorial processes in A. huettingeri (Fig.
