Material examined
IRAN • 1 ♂; West-Azarbaijan Province , Urmia, Hesar-e Türkmän; 37º26′ N, 45º13′ E; 1293 m a.s.l.; Apr. 2017; Y. Karimpour leg.; ex Phragmites australis ; HMIM GoogleMaps .
Remarks
Asitus phragmitis ( Ferrière, 1955) is a parasitoid of Pseudococcidae on Phragmites australis in the Caucasus, several European countries, USA and Pakistan ( Ferrière 1955; Guerrieri 1989; Noyes 2020). Our specimen is closely related to A. phragmitis and shares several characters with that species: body
dorsoventrally flattened; head prognathous, head and mesosoma finely reticulate; antennae inserted just above clypeus and widely separated from each other; pronotum divided into two subtriangular parts; notauli absent; scutellum wider than long, about 1.9× as wide as long, anteriorly reaching the base of the tegula. However, it differs from A. phragmitis in several characters ( Table 2 View Table 2 ) and in our opinion very probably represents a new species. Because we only sampled a single male, we will not describe this species and await further samples.
