Schmid-Egger, Christian, Kaplan, Emin & Yildirim, Erol, 2021, Three new species of Agenioideus Ashmead, 1902 and Priocnemis Schioedte, 1837 (Hymenoptera: Pompilidae) from Turkey, Zootaxa 5040 (1), pp. 141-148 : 142-143

Agenioideus (Mimochares) karsensis Schmid-Egger, Yildirim & Kaplan sp. nov.

( Figs 1–4 )

Holotype: ♀ TURKEY, Kars, Sarıkamış, Karakurt , [N40.16 E42.60], 1500 m, 24.vii.2010 (leg. E. Yildirim, coll. ABBM).

Diagnosis: Agenioideus karsensis sp. nov. is similar to Agenioideus coronatus (Nouvel & Ribaut, 1958) , in the subgenus Mimochares Wahis, 1972 . Both species, A. coronatus and A. karsensis sp. nov. are characterized by a comma-shaped yellow spot on the inner eye margin ( Fig. 2 ), a small pterostigma compared to other Agenioideus species ( Fig. 3 ), and the lack of foretarsal spines. Agenioideus karsensis sp. nov. differs from A. coronatus by the following characters (characters of A. coronatus given in parentheses): horizontal part of comma-shaped spot of inner eye margin shorter than vertical part ( Fig. 2 ) (horizontal part longer than vertical part, sometimes connected with spot on other side by band); T2–3 and S2 partly red ( Fig. 1 ) (all black or only T2 with some red); femora, tibiae and tarsi light red (femora dark, tibiae and tarsi dark red), OOL = 1.5x hindocellar diameter ( Fig. 4 ) (OOL = 2.0–2.5x hindocellar diameter).

Description of female holotype: Body length 7.9 mm. Colour. Black, with the following parts yellowish-reddish: mandible (apart dark apex), band on apical third of clypeus, AS 1 below, comma-shaped spot on inner eye margin ( Fig. 2 ), thin bands on upper and outer eye margin, band on pronotum apically ( Fig. 1 ). Reddish are: T1 laterally, T2 apart apex, red band of T2 apically triangulary emarginated, basal half of T3, S2 apart of apex; coxa and trochanter in apical part, all femora, tibae and tarsi. Forewing transparent with infuscate zone in apical third (near marginal and submarginal cells), apex whitish transparent. Lower half of face with fine silver pilosity, not hiding integument. Propodeum apico-laterally with dense patch of white pilosity. Morphology. ACM straight. Head 1.3x wider than long. Eye as large as half face (remaining part of face without eye, measured above antennal socket). AS 3 1.2x as long as AS 1+ AS 2 combined. OOL = 1.5x hindocellar diameter. Metapostnotum medially as long as metantotum, laterally somewhat shorter, basally with three fine striae, remaining part finely sculptured. Remaining surface of mesosoma dull, impunctate. Foretarsomeres without lateral spines, foremetatarsus with two short spines below and two short spines apically, each spine at most as long as tarsal diameter.

The male is unknown.

Distribution: Eastern Turkey.

Etymology: The name is derived from the area of origin of the holotype. Kars is a province in northeastern Turkey.

Remarks: Agenioideus karsensis sp. nov. keys out with Agenioideus coronatus (Nouvel & Ribaut, 1958) , subgenus Mimochares Wahis, 1972 , in the key by Wolf (1986). Agenioideus coronatus occurs in northwest Africa and southwest Europe only ( Gros & Wahis, 2002) and was so far the only species in this subgenus. It was never reported from the eastern Mediterranean area or from Turkey.
