Diaeretus leucopterus (Haliday, 1834)

M a t e r i a l. 1 ♀, Кyiv Region, Borodianka Distr., near Klavdievo [50°35'15.01'' N, 29°59'56.49'' E], sweeping in the forest ( Betula, Pinus ) and on fern in a swamp, 23.05.197 6 (А. Kotenko) ( SIZK) .

C o m m e n t. Three species of the genus Diaeretus are known worldwide, and D. leucopterus is the only one species present in the Palearctic Region (Yu et al., 2012).

С o m p a r a t i v e n o t e s. D. leucopterus ( fig. 4 ) morphologically is similar to species from monotypic genus Diaeretiella — D. rapae M’Intosh , from which it differs by:1) antenna with 16–18segments; 2) mesoscutum without notauli; 3) shorter radial vein of forewing: its length equal to stigma width; 4) propodeum with transverse carina and without central areola; 5) petiole with slightly visible longitudinal tubercle and without central carina; 6) almost square ovipositor sheath, not thinned to the apex; 7) form of the apex of ovipositor sheath.

H o s t s. Species of Eulachnus genus on Pinus are the main hosts: E. agilis , E. mediterraneus , E. rileyi , E. thunbergii , E. tuberculostemmatus ( Starý, 1976, 2006; Tobias, Chiriac, 1986; Davidian, 2007; Starý, Lukáš, 2009; Yu et al., 2012). In addition, there is an information about D. leucopterus parasitizing on Cinara piniformosana and Schizolachnus pineti on Pinus , and on Mindarus abietinus associated with coniferous trees. Brachycaudus cardui and Schizaphis graminum are also mentioned as host species, but these data have not been confirmed in latest publications (Yu et al., 2012).

H a b i t a t s. Mixed forests, pine forests, coniferous forests edges, parks ( Starý, 2006).

D i s t r i b u t i o n. Ukraine (Кyiv Region, first record). Europe (except North Europe), Near East ( Israel), Asia: Central ( Uzbekistan, Tajikistan), Eastern ( China, South Korea, Japan), Southern ( India), and South-Eastern ( Thailand) ( Tobias, Chiriac, 1986; Davidian, 2007; Yu et al., 2012).
