Abstract

A new species from Turkey, Avteon leleji sp. nov. (Hymenoptera, Dryinidae), is described and illustrated.
Its relationship with Palaearctic and Afrotropical species of Anteon is discussed. The new species is close to
A, xericum Olmi & van Harten described from Yemen, and known also from other Afrotropical countries.
The key to the Palaearctic species of Anteon is modified to include the new species. New records of Anteon

species from Turkey are registered.

Introduction

Dryinidae (Hymenoptera, Chrysidoidea) are parasitoids and often also predators of
leafhoppers, planthoppers and treehoppers (Hemiptera, Auchenorrhyncha) (Gug-
lielmino et al. 2013). The family consists of 52 genera (Olmi et al. 2020), includ-
ing Anteon Jurine, 1807. This genus includes 464 species and is known to parasitize

leafhoppers of the family Cicadellidae (Olmi et al. 2019). Anteon species can be easily
recognized for the following characters (see Olmi et al. 2019 for keys and figures): fe-
male with distinct ocelli; fore wing with distal part of 2r-rs&Rs vein much shorter than
proximal part; chelate protarsus; rudimentary claw absent; inner side of the enlarged
claw with a proximal prominence bearing one long bristle; male with three basal cells
of the fore wing completely enclosed by pigmented veins; fore wing with PostabR1
(= radius) absent or shorter than pterostigma; pterostigma less than 4 x as long as
broad; distal part of 2r-rs&Rs vein much shorter than proximal part; hypopygium not
umbrella-shaped.

In the Western Palaearctic region, the genus Azteon can be considered sufficiently
known in Western Europe mainly because of the papers of Olmi (1999, 2021). On the
contrary in Eastern Europe and the Middle East it is insufficiently known due to lack
of research (Olmi 2011; Derafshan et al. 2021). In Turkey, the following six species of
Anteon are known (Olmi and Xu 2015; Olmi et al. 2019): Anteon abdulnouri Olmi,
1987; Anteon ephippiger (Dalman, 1818); Anteon infectum (Haliday, 1837); Anteon
jurineanum Latreille, 1809; Anteon pubicorne (Dalman, 1818); Anteon scapulare (Hali-
day, 1837).

In 2020, we received on loan a specimen of Anteon collected in Turkey. It resulted
to be a new species described herein.

Materials and methods

The description follows the terminology used by Olmi et al. (2019). The measure-
ments reported are relative, except for the total length (head to abdominal tip, exclud-
ing antennae and sting), which is expressed in millimetres. The following abbreviations
are used in the descriptions: POL — the distance between the inner edges of the two
lateral ocelli, OL — the distance between the inner edges of a lateral ocellus and the
median ocellus, OOL — the distance from the outer edge of a lateral ocellus to the
compound eye, OPL — the distance from the posterior edge of a lateral ocellus to the
occipital carina, TL — the distance from the posterior edge of an eye to the occipital
carina. The term “disc of metapectal-propodeal complex” is here used in the sense of
Kawada et al. (2015). It corresponds to the term “dorsal surface of propodeum” sensu
Olmi (1984). The term “propodeal declivity” sensu Kawada et al. (2015) used here,
corresponds to the term “posterior surface of propodeum” sensu Olmi (1984). The
names of veins of the forewing are here used in the sense of Olmi et al. (2019). The
“stigmal vein” (sensu Olmi 1984) is here named “second radial-radial sector crossvein
& radial sector vein (2r-rs&Rs)”.

The types of all Palaearctic species of Anteon have been previously examined by
the authors.

The specimens examined in this paper were studied by a stereomicroscope Wild
M5. The multifocal photos were taken by one of the coauthors (LC) using a mirror-
less camera Sony Alpha 6300 with cross table Proxxon KT 70. Captured images were

merged into a single in-focus image using ZereneStacker version 1.04. Plates were
composed by Photoshop CS6. Line drawings were made by a camera lucida combined
with a microscope Leitz Laborlux 12.

The specimen studied in this paper is deposited in the collections of the Oberéster-
reichisches Landesmuseum, Linz (Austria) (OLL).

cept mandible testaceous and antenna and legs brown. Antenna filiform; antenno-
meres in following proportions: 9:5:6:7:6:6:6:6:6:8 (antennae broken; last four an-
tennomeres glued on the label (Fig. 1E)). Head (Fig. 1D) dull, granulate and slightly

keel separating disc and propodeal declivity; metapectal-propodeal disc reticulate ru-
gose; propodeal declivity (Fig. 1F) without longitudinal keels, with areolae less wide
than those of metapectal-propodeal disc. Fore wing hyaline, without dark transverse

Etymology. The species is named after Prof. Arkady S. Lelej (Federal Scientific
Center of the East Asia Terrestrial Biodiversity, Far Eastern Branch of the Russian Acad-
emy of Sciences, Vladivostok, Russia) on the occasion of his seventy-fifth birthday.

Distribution. Turkey.

Remarks. Because of the above diagnosis, A. /eleji sp. nov. is similar to A. xericum
Olmi & van Harten, 2006, species described from Yemen, but Afrotropical, being

known also from Kenya, Madagascar, South Africa and Tanzania (Olmi et al. 2019).
From the point of view of Dryinidae, Yemen is mainly Afrotropical. However, there are
a few exceptions represented by Palaearctic species, such as Anteon abdulnouri Olmi,
1987 and Echthrodelphax tauricus Ponomarenko, 1970 (Olmi 1999, 2021; Olmi et
al. 2019). For this reason, Yemen is also treated as a Palaearctic country, albeit at the
margins (see Olmi et al. 2019 for further comments). Following the above description
of A. leleji sp. nov., the key to the males of the Western Palaearctic species of Anteon
published by Olmi (1999), should be modified by replacing couplet 3 as follows:

Discussion

Species of the genus Anteon usually have very large geographic distributions (Olmi
1999; Olmi et al. 2019). Species that have been recorded from only one country
or region are expected to be found in other regions in future. Azteon leleji sp. nov.
should not be an exception. As Western Europe is well known, probably A. /eleji
sp. nov. should be a species present in the Middle East or maybe also in East-
ern Europe. The Middle East is insufficiently known. Recent investigations in Iran
(mainly thanks to Prof. Ehsan Rakhshani research group, Zabol University, Iran)
(Derafshan et al. 2016, 2017, 2020, 2021) are trying to fill this gap. However, the
work is hard, since the Middle East covers wide range and the number of involved
researchers is too small.

Another big gap regards the hosts of Anteon. They are almost unknown in the
entire Middle East. The species, whose hosts are recorded in the Middle East, are only
two (Guglielmino et al. 2013).

Following the description of A. /eleji sp. nov., eight are the Anteon species recorded
in the Middle East (Olmi 1999, 2021; Olmi and Xu 2015; present paper), of which
seven registered from Turkey. However, the species present in Turkey are more numer-
ous. We can register here the following six new records, based on material identified by

the authors and deposited in OLL:

1. Anteon flavicorne (Dalman, 1818): from Turkey, Samsun, University campus,

Following the above new records, the species of Anteon recorded from Turkey are
now 13.
