T y p e d e s i g n a t i o n s: Designation of the female neotype of Bracon abbreviator NEES identical with the female lectotype of Bracon rufigaster SZÉPLIGETI : (first label, printed) "Fonyód / Szépligeti"; second label is the lectotype card of B. rufigaster given by me (in 1968); third label is the inventory number 1394; fourth label is the neotype card of B. abbreviator NEES. - Neotype (or lectotype) is in fairly good condition: (1) micropinned; (2) left flagellum distally deficient. - The designation of the female neotype of B. abbreviator NEES was needed because (1) the destruction of the Nees Collection at the end of the second world war and (2) its unambiguous distinction from the two species ( B. curticaudis SZÉPLIGETI , B. minutator FABRICIUS ) standing very near to it. The selection of the lectotype of B. rufigaster for the neotype status is justified by its matching in all respects to the original description of B. abbreviator by Nees (l.c.). After the description of B. abbreviator by NEES in 1834 the species have been described again by WESMAEL (1838) and by MARSHALL (1897) under the names oostmaeli, regularis (by Wesmael) and eutrephes (by Marshall). The type series of B. oostmaeli and B. eutrephes are in poor condition, on one hand, and the type series of B. regularis is based on three male specimens, on the other - namely the three type series are unappropriate to select of them the neotype specimen.

Designation of the female paralectotype of B. rufigaster SZÉPLIGETI : (first label, printed) "P.-Maróth / Szépligeti" (= Pilismarót , Hungary) ; second label is the paralectotype card given by me (in 1968); third label is with the inventory number 1395; fourth label is with the actual name B. abbreviator NEES given by me. - Paralectotype is in fairly poor condition: (1) pinned by mesosoma; (2) right flagellum missing, left flagellum apically deficient; (3) missing: right fore leg (except coxa), tarsomeres 2-5 of right middle and hind legs, tibiae + tarsi of left middle and hind legs.

Designation of the female lectotype of Bracon eutrephes MARSHALL : (first label attached by me in 1989, my handscript) " Spain / Iles Baléares / Palma de Mallorca"; (second label medio-longitudinally with a red line) "eutrephes M." (handscript) / "Coll. Marshall" (printed); third label is the lectotype card given by me (in 1990); fourth label is with the inventory number 10556; fifth label is with the actual name B. abbreviator NEES given by me. - Lectotype is in rather poor condition:(1) micropinned; (2) body more or less mouldy; (3) antennae (except left scape + pedicel) and tarsomeres 4-5 of right hind leg missing.

Designation of the female lectotype of Braco oostmaeli WESMAEL : (first label, printed) "Coll. Wesmael"; (second label, printed) "2083"; (third label, printed red) "Type"; (fourth label) "Braco oostmaeli mihi " (handscript) "det. C. Wesmael" (printed); fifth label is with the locality name " Belgique / Oostmael / Campine" given by me (with my handscript); sixth label is the lectotype card attached by me; seventh label is with the actual name B. abbreviator NEES given by me; - Lectotype is in fairly poor condition: (1) micropinned (micropin thick); (2) head missing; (3) missing: right fore wing, right fore leg, tarsomeres 3-5 of left fore leg.

Designation of the male lectotype of Braco regularis WESMAEL : (first label, printed) "Coll. Wesmael"; (second label, printed) "2057"; (third label, printed red) "Type"; (fourth label) "Braco regularis mihi " (handscript) "det. C. Wesmael" (printed); fifth label is with the locality name " Belgique / Bruxelles " given by me (with my handscript); sixth label is the lectotype card attached by me; seventh label is with the actual name B. abbreviator NEES given by me. - Lectotype is in fairly good condition: (1) micropinned; (2) flagelli apically deficient; (3) right hind leg (except coxa + trochanters) missing.

Designation of the two male paralectotypes of Braco regularis WESMAEL : labels 1-5 and 7-8 are identical to those of the lectotype; sixth label is the paralectotype card attached by me. - Two paralectotypes are in fairly good (1) and fairly poor (1) condition: (1) micropinned); (2) flagelli apically deficient; (3) metasoma and fore pair of legs (except coxae + trochanters) missing (1).
