T y p e d e s i g n a t i o n s: Designation of the female holotype of B. ochraceus : (first two labels) "Crkvenica" (printed) / "25. VI." (handwriting, according to the original description taken in the year 1892), " Croatia "; third label is the holotype card, fourth label is with the inventory number "1350", fifth label is with the actual name B. (Lu) ochraceus given by me in 2006. - Holotype is in fairly good condition: (1) micropinned, micropin covered with copper vitriol crystals, left fore leg partly "hidden" by the crystals; (2) both flagelli deficient; (3) tarsomeres 4-5 of right middle leg missing; (4) right hind wing missing.

Designation of the female holotype of B. gracilis : (first label, printed) " Budapest / Sas- hegy"; (second label) [1]"896. VI. 17." (handwriting) " Szépligeti " (printed) ; third label is the holotype card, fourth label is with the inventory number "1351"; fifth label is with the actual name B. (Lu) ochraceus SZÉPLIGETI given by me in 2006. - The holotype is in fairly poor condition: (1) micropinned laterally by mesosoma; (2) left antenna missing, right flagellum deficient distally; (3) metasoma broken and glued to propodeum; (4) left oviposior sheath deficient (present its anterior fourth).

R e m a r k on the above type designations: (1) The species B. ochraceus was described in 1896, however, in his revisional paper SZÉPLIGETI (1901a) did not take it into consideration, i.e. it was not included in the key to the European species of the genus Bracon , on one hand, and a new species was described in 1901a by him under the name B. gracilis , on the other. The two descriptions unambiguously refer to the same species, the repeated description (under the new species name) is a taxonomic enigma. - (2) In my paper ( PAPP 2004) I placed the names B. gracilis and B. ochraceus in synonymy with B. flagellaris THOMSON. A re-identification of these three taxa led me to the recognition that B. ochraceus (= gracilis) differs from B. flagellaris by subgeneric as well as a few specific features keyed: 1 (2) Oral opening less large, its horizontal diameter 1.4-1.5 times as long as shortest

distance between opening and compound eye (subgeneric difference of

Glabrobracon , Fig. 275 ). Tergites 2-3 polished, second tergite antero-medially

striolate-substriolate ( Fig. 276 ). Vein SR1 of fore wing reaching tip of wing ( Fig.

277). Hind femur 3.3-3.4 times as long as broad ( Fig. 278 ).: 3.2-3.5 mm ................

.................................................................................. B. (Gl.) flagellaris THOMSON 1894 2 (1) Oral opening large, its horizontal diameter twice as long as shortest distance

between opening and compound eye (subgeneric difference of Lucobracon , Fig.

262). Tergites 2-3 rugo-rugulose ( Fig. 268 ). Vein SR1 of fore wing approaching tip

of wing ( Fig. 266 ). Hind femur 2.8-2.9 times as long as broad ( Fig. 264 ).: 2.2-3

mm ............................................................................ B. (L.) ochraceus SZÉPLIGETI 1896

By this distinction the species B. ochraceus is revalidated. The synonymization explains the absence of B. (Lu.) ochraceus from the revision of the Bracon (Lucobracon) species by SZÉPLIGETI ( PAPP 2005). The present revalidation is an addition to this revision.

M a t e r i a l e x a m i n e d (2 + 2): Two female holotypes of B. ochraceus (from Croatia) and B. gracilis (from Hungary). Croatia: 1. Spain: 1.

R e d e s c r i p t i o n of the female holotype of B. ochraceus: Body 3 mm long. Right antenna deficient, i.e. flagellum with 16 flagellomeres. First flagellomere twice and 16 th flagellomere 1.2 times longer than broad, flagellomeres proximo-distally slightly thickening. According to the original description antenna with 28 antennomeres. - Head in dorsal view ( Fig. 260 ) less transverse, nearly 1.6 times as broad as long, eye nearly 1.4 times as long as temple, temple rounded, occiput weakly excavated. Eye in lateral view ( Fig. 261 ) 1.45 times as high as wide and one-fifth wider than temple, temple evenly wide beyond eye. Oral opening large, its horizontal width twice as long as shortest distance between opening and compound eye ( Fig. 262 ). Head polished; face laterally just (or very finely) granulose.

Mesosoma in lateral view nearly 1.7 times as long as high, polished. Notaulix distinct, i.e. moderately deep and smooth. Propodeum polished, along its hind margin crenulateshaped ( Fig. 263 ). - Hind femur somewhat less than 2.6 times as long as broad distally ( Fig. 264 ). Claw curved with distinct basal lobe as in Fig. 265 .

Fore wing about as long as body. Pterostigma ( Fig. 266 ) three times as long as wide and issuing r from its middle; r one-sixth shorter than width of pterostigma; 3-SR a bit longer than 2-SR (i.e. second submarginal cell short), SR1 straight, almost twice as long as 3-SR and approaching tip of wing; 1-R1 somewhat less than 1.5 times as long as pterostigma ( Fig. 266 ). First discal cell less high, 1-M almost 1.9 times as long as m-cu, the two veins not parallel with each other ( Fig. 267 ).

First tergite ( Fig. 268 ) as long as broad behind, beyond pair of spiracles weakly broadening, hind part of scutum rugo-rugulose with striate elements, margin of scutum crenulate. Second tergite clearly twice as broad behind as long laterally; tergites 2-3 equal in length, suture between them bisinuate, subcrenulate. Second and third tergite rugo-rugulose ( Fig. 268 ), rest of tergites smooth and shiny. Hypopygium elongate and pointed, ovipositor sheath long, as long as hind femur + tibia + tarsus combined.

Ground colour of body reddish yellow with dark colour pattern. Dark brown: antenna, propodeum, scutum of first tergite and small antero-median macula on second tergite. Legs yellow, hind tibia apically and hind tarsus entirely brown. Wings subhyaline, pterostigma yellow, veins brownish yellow.

Deviating features of the female holotype of B. gracilis: Body 3 mm long. Temple in dorsal view somewhat less rounded ( Fig. 269 ). Second submarginal cell somewhat less short, 3-SR 1.3 times as long as 2-SR ( Fig. 270 ). Rugo-rugulosity of second tergite somewhat less strong ( Fig. 271 ).

D e s c r i p t i o n of the male (2). - Similar to the female. Body 2.2 mm (1) and 2.5 mm (1) long. Antenna as long as body and with 24 antennomeres (1). First flagellomere three times and penultimate flagellomere twice as long as broad. Sculpture of tergites 1-3 stronger, rest of tergites with gradually weakening rugulo-subrugulosity.

H o s t: unknown.

D i s t r i b u t i o n: Hungary, Croatia, Spain.

R e m a r k s: Within the subgenus Lucobracon the species B. ochraceus is nearest to B. fortipes WESMAEL viewing their vein SR1 approaching tip of wing and ground corporal colour is reddish yellow; the distinctive features between the two species are keyed: 1 (2) Head in dorsal view transverse, 1.7-1.85 times as broad as long ( Fig. 272 ). Tergites

2-3 broad, second tergite 3.3-3.5 times as broad behind as long laterally and

somewhat shorter than third tergite ( Fig. 273 ). Second submarginal cell long, 3-SR

(1.25-)1.4 times length of 2-SR ( Fig. 274 ). Pterostigma light brownish.: (3-)3.5-

4.3 mm,: 2.8-3.5 mm ................................................. B. (Lu) fortipes WESMAEL 1838 2 (1) Head in dorsal view less transverse, 1.5-1.6 times as broad as long ( Figs 260, 269 ).

tergites 2-3 equal in length ( Fig. 268 ). Second submarginal cell less long, 3-SR 1.1-

1.3 times as long as 2-SR ( Figs 266, 270 ). Pterostigma yellow.: 3 mm,: 2.2-2.5
