T y p e d e s i g n a t i o n: Designation of the female lectotype of Bracon minutator   : (first label) "minutator" (original handwriting by Fabricius?); second label is the lectotype card by Van Achterberg 1980; third label is with the locality name " Germania / Halae Saxonum" adopted after Fabricius l.c. and attached by me. - Lectotype is in fairly good condition: (1) pinned by mesosoma, pin fairly thick and pricked on a polyporus stage; (2) body and wings somewhat dirty and with (mouldy?) filaments; (3) left flagellum missing, right flagellum deficient, i.e. only with 12 flagellomeres.  

R e m a r k s on the lectotype of B. minutator   : (1) The species B. minutator   , together with B. urinator   , are the first two species described by FABRICIUS in 1798 originally in the genus Ichneumon and later, in 1804, he transfered them into the genus Bracon   which genus has been created by him. - (2) Van ACHTERBERG (l.c.) pointed out that in the Fabricius Collection (Copenhagen) the type series of B. minutator   consists of four female specimens of which the first female is representing the true B. minutator   ; the rest of the three females (without original labels) are not conspecific and were identified by me as follows: 1: B. caudiger NEES   , 1: B. subrugosus SZÉPLIGETI   and 1: B. variator NEES   (this latter specimen is representing a light or albanic form of the nominate B. variator   viewing its metasoma with yellow ground colour and tergites medially with a row of dark maculae). - (3) The female lectotype of B. tener   is identical with the female lectotype of B. minutator   , consequently, several specific features observed somewhat less well on the lectotype of B. minutator   were quasi controlled on those of the lectotype of B. tener   .

Designation and condition of the types (female lectotype and three female paralectoty-

pes) of B. tener SZÉPLIGETI   see in PAPP 2004: 182.

Legs light reddish yellow, coxae black, femora 1-2 basally and tibiae 2-3 apically blackish to dark brown. Wings subfumous, pterostigma and veins light brown.

Variability of the females (67): Similar to the female lectotype. Body 4-4.5(-5) mm long. Antenna about as long as body and with 29-33 antennomeres. First flagellomere 1.6-1.8 times and penultimate flagellomere 1.5-1.7 times as long as broad, flagellum proximo-distally slightly attenuating ( Fig. 216 View Figs 209-219 ). Head in dorsal view ( Fig. 217 View Figs 209-219 ) 1.8-1.9 times, usually 1.8 times, as broad as long, eye 1.3-1.4 times longer than temple, temple rounded ( Figs 209, 217 View Figs 209-219 ) to less rounded (cf. Fig. 15 View Figs 15-23 ). Hind femur 3.1-3.3 times as long as broad medially (cf. Fig. 16 View Figs 15-23 , Fig. 212 View Figs 209-219 ). First tergite parallel-sided, third tergite longer than second tergite (cf. Fig. 17 View Figs 15-23 ). Tergites 2-3 or tergite 2 rarely rugulose ( Fig. 218 View Figs 209-219 ) to rugose. Pair of carinae of scutum frequently missing, or, rarely, distinct (cf. Figs 17 View Figs 15-23 , Fig. 215 View Figs 209-219 ). Hind femur proximally blackish (4) or black pattern of legs more extended than in the female lectotype. Black maculae of tergites of variable extend to almost entirely black tergites (9).

D e s c r i p t i o n of the males (38): Similar to the females. Body (3.2-) 3.5-4.5 mm long. Antenna somewhat longer than body and with (26-)30-35 antennomeres. Flagellomeres 1.8-2.4 times longer than broad. Hind femur 3-3.3 times as long as broad medially or somewhat distally. First tergite usually somewhat longer than broad behind, its sides either slightly broadening ( Fig. 219 View Figs 209-219 ) or parallel. Legs frequently with less black(ish) pattern.

H o s t uncertain: SHENEFELT (1978) listed 9 lepidopterous, 7 dipterous and 2 coleopterous host species, all are in need to be confirmed owing to the misinterpretation of the braconid parasitoid B. minutator   .

D i s t r i b u t i o n: Europe.
