Zhu, Chao-Dong, 2017, Notes on Kocourekia Bouček (Hymenoptera: Eulophidae: Tetrastichinae) with description of a new species from China, Zootaxa 4317 (2), pp. 391-400 : 393

2. Kocourekia debilis ( Ratzeburg, 1852)

Entedon debilis Ratzeburg, 1852: 210 ; ♀. Holotype, NHMV (not examined).

Kocourekia hirtula Bouček, 1966: 378 –379; ♀. Holotype, NMP (not examined).

Diagnosis (female). Body dark brown; scape, pedicel and legs dark brown except for tarsi. Each funicular segment distinctly transverse; F1 about 1/2 length of F2. Gena without malar sulcus. Toruli inserted at or slightly below lower ocular line. Scutellum with numerous setae uniformly scattered over entire surface, without a bare median line.

Examined material. Paratypes of Kocourekia hirtula Bouček : 9♀, S. Moravia, Mutenice, 1958, M. Kocourek, ex. galls of Cynips kollari Hartig (NMP, NO. 26. 090–26. 098).

Biology and hosts. Presumably a gregarious parasitoid. The type specimens of K. hirtula (= K. debilis ) were reared from an unknown host dwelling in galls of Andricus kollari (Hartig) ( Hymenoptera , Cynipidae ). Based on the possible close relationship of Kocourekia with Melittobia and the then likelihood they might have a similar biology, Bouček (1966) postulated that the unknown host of K. kirtula might be some aculeate Hymenoptera dwelling in galls. According to the records of K. debilis by Ratzeburg (1852), Graham (1991) presumed that the host of the type specimens might be some species of Pemphredoninae ( Hymenoptera , Sphecidae ).

Distribution. Europe ( Bouček 1966, 1977), North America (LaSalle 1994).
