Material examined.

Holotype: ♂, Turkey, Mugla Prov., Mugla university campus, 37°09'38"N, 28°22'11"E, XI.2015 - IV.2016, Malaise trap, Barták & Kubík leg. (OLL).

Diagnosis.

Macropterous male of Anteon with mesoscutum punctate, unsculptured among punctures (Fig. 1A ); propodeal declivity without longitudinal keels (Fig. 1E ); paramere with numerous transverse folds and papillae on inner margin (Fig. 2A ).

Description.

Male. Fully winged (Fig. 1A-C ); body length 2.1 mm. Black, except mandible testaceous and antenna and legs brown. Antenna filiform; antennomeres in following proportions: 9:5:6:7:6:6:6:6:6:8 (antennae broken; last four antennomeres glued on the label (Fig. 1E )). Head (Fig. 1D ) dull, granulate and slightly rugose; frontal line indistinct, complete; occipital carina complete; POL = 6; OL = 3; OOL = 5; OPL = 3.5; TL = 4; greatest breadth of lateral ocellus about as long as OL. Mesoscutum (Fig. 1A ) shiny, punctate, unsculptured among punctures. Notauli incomplete, reaching approximately 0.3 × length of mesoscutum. Mesoscutellum and metanotum shiny, unsculptured. Metapectal-propodeal complex with transverse keel separating disc and propodeal declivity; metapectal-propodeal disc reticulate rugose; propodeal declivity (Fig. 1F ) without longitudinal keels, with areolae less wide than those of metapectal-propodeal disc. Fore wing hyaline, without dark transverse bands; distal part of stigmal vein (2r-rs&Rs) much shorter than proximal part (3:7). Paramere (Fig. 2A ) without inner process, with numerous transverse folds. Tibial spurs 1/1/2.

Female. Unknown.

Hosts.

Unknown.

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 Academy of Sciences, Vladivostok, Russia) on the occasion of his seventy-fifth birthday.

Distribution.

Turkey.

Remarks.

Because of the above diagnosis, A. leleji 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:
