Cheiloneurus paralia (Walker, 1837)

Fig. 3

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 .

Remarks

Our specimen fits well the description given by Claridge (1958), but the head exhibits a faint metallicgreen tinge ( Fig. 3A, C ). Body mainly rufo-fuscous ( Fig. 3A ), funicle with three white segments, F6 black ( Fig. 3B ); mesonotum entirely greenish; fore wings mainly fuscous except basally and distally ( Fig. 3D ); propodeum and abdomen dark with blue-green reflections; scape approximately 5× as long as wide, funiclar segments almost quadrate, club slightly widened, truncate apically ( Fig. 3B ); scutellar ‘hair-brush’ well developed ( Fig. 3C ); gaster short, as long as thorax.

This species is widely distributed in the Palaearctic region ( Noyes 2020) and in Iran ( Fallahzadeh & Japoshvili 2010). Cheiloneurus paralia is a parasitoid of different mealybug families ( Asterolecaniidae Cockerell, 1896 , Cerococcidae Balachowsky, 1942 , Coccidae Stephens, 1829 , Eriococcidae Cockerell 1899 , Kermesidae Kosztarab, 1996 and Pseudococcidae ) on Poaceae such as Festuca rubra L. ( Claridge 1958; Noyes 2020). Therefore, it may be associated with a pseudococcid species on P. australis . It has been reported on Peliococcus kimmericus (Kiritshenko, 1940) on Lactuca serriola L. ( Asteraceae ) in Iran ( Fallahzadeh et al. 2006).
