Ceranisus pacuvius (Walker) View in CoL : Bakkendorf 1957: 1–8; Graham 1959: 203; 1963: 203; Boucek 1961: 26; Boucek & Askew 1968: 137, 138; Trjapitzin 1978: 426; Loomans & van Lenteren 1995: 115– 119, 196; Thuróczy & Jenser 1996: 151–153.

Diagnosis: This species was redescribed and illustrated in detail by Bakkendorf (1957). Therefore, only a brief diagnosis is given here.

Female. Body dark brown to black (basal 1/4 of gaster sometimes a little lighter but at least brown), appendages light brown to brown. Antenna ( Fig. 53 View Figs 53–56 ) with scape 4–5 x as long as wide; F1 notably longer than wide, usually with 1 sensillum but sometimes without sensilla, F2 wider than F1, with 1 or 2 sensilla; basal segment of clava slightly shorter than distal claval segment. Forewing ( Fig. 54 View Figs 53–56 ) about 2.8 x as long as wide; longest marginal setae about 3/10 maximal width of forewing; disc with numerous short setae, more or less uniformly setose beyond base of marginal vein. Ovipositor occupying about 3/5 length of gaster, not exserted.

Male. Similar to female except for normal sexually dimorphic features and darker colouration of body and appendages. Antenna ( Fig. 55 View Figs 53–56 ) with scape strongly dilated, almost smooth, 1.4–1.7 x as long as wide; funicle as in female, F1 with 1 sensillum, F2 with 2–3 sensilla; clava longer than funicle, about 2.0 x as long as wide. Genitalia as in Fig. 56 View Figs 53–56 .

Material examined: Lectotype male of C. pacuvius on card [ BMNH], labelled:1. “ Pacuvius ”; 2. “ Lectotype ”; 3. “LTơ Ceranisus pacuvius (Walk.) det. Z. Boucek 1980”; 4. “ B. M. Type Hym 5.2711”.

Lectotype female of E. acestor on card [ BMNH], labelled: 1. “ Lectotype ”; 2. “ 4385 ”; 3. “ Entedon acestor Walker ”; 4. “ B. M. Type Hym 5.2712”.

Lectotype female of D. aculeo on card [ BMNH], labelled: 1. “ Diglyp. aculeo W. 48 Lectotype^ M. de V. Graham det. 1974”; 2. “ B. M.Type Hym 5.2711”; 3. “ Lectotype ”; 4. “ Lectotype ”; 5. “ Aculeo ”. Also examined were 2 female paralectotypes [ BMNH], labelled as “ aculeo ”.

Lectotype female of T. kutteri , here designated to avoid confusion about the identity of this species, on slide labelled: 1. “ SUISSE Flawil - 1935 H. Kutter Ex Kakothrips robustus ds. pois”; 2. “ Tetrastichinae : Thripoctenus kutteri^ Ch. Ferriere [“det.” -crossed out] cotype.”; 3. “ Thripoctenus kutteri Ferrière LECTOTYPE^ Des. by S. V. Triapitsyn 2000”; 4. “ Ceranisus pacuvius (Walker) Det. S. V. Triapitsyn 2000 ” [BMNH]. Paralectotypes of Thripoctenus kutteri Ferrière , here designated: 1^ on slide as well as 2^ and 1ơ on a separate slide, same label data as the lectotype [BMNH].

Other material examined: GREAT BRITAIN: Berkshire: Berkshire Downs (nr Streatley): 14.vi.1975, J.S. Noyes, 7ơ; 30.vi.1975, J.S. Noyes, 7ơ. Hampshire: Southampton: 25.v.1977, L.A. Mound, 2^ (“ex. Sarothamnus scoparius ”); vi.1977, L.A. Mound, 2ơ [BMNH]. HUNGARY: Bükk, 7.vii.1959, J. Erdös, 1ơ (det. G. Szelényi ). Kalocsa, 1.vi.1945, J. Erdös, 1^ (on Picea excelsa , det. G. Szelényi ). Mecsek, 19.v.1949, J. Erdös, 1ơ. Ohat, 24.iv.1975, Hámoriné, 1ơ (det. G. Szelényi ). Tompa, 9.v.1949, J. Erdös, 1ơ [HNHM]. Also all the specimens reported by Thuróczy & Jenser (1996) (det. C. Thuróczy) [SPLK].

Distribution: Europe (Loomans & van Lenteren 1995; Teulon et al. 1996). Following Boucek (1961), Trjapitzin (1978) reported this species from Moldova but at least specimens in ZIN actually belong to C. planitianus .

Hosts: See Loomans and van Lenteren (1995).

Comments: Examination of the lectotype of Diglyphus aculeo Walker (in BMNH) revealed that it belongs to C. pacuvius rather than to C. menes .
