Taxonomic remark

The genus Pigeria   was described by van Achterberg (1985), who assigned two European species to it: P. piger ( Wesmael, 1838)   and P. wolschrijni van Achterberg, 1985   . Quicke & Sharkey (1989: 350) noted that “Although Pigeria   is being kept separate from Bracon   in the present paper, it is probably best considered as only a derived subgenus of the latter.” In this paper taxon Pigeria   is suppressed to subgeneric level and regarded as one of the subgenera of Bracon   .

Designation of the ♀ lectotype of Bracon piger  

(First label, printed) “ Coll. Wesmael ”; (second label, printed) “2062”; (third label) “ Braco   ♀ / piger mihi” (handwriting) / “det. Wesmael ” (printed); (fourth label, printed red) “Type”; fifth label (printed) is with the (?)inventory number “3.317”; sixth label (printed) with the locality Bruxelles after Wesmael ; seventh label is the lectotype card (sixth and seventh labels attached by me). Lectotype is in good conditition: (1) micropinned; (2) right flagellum deficient (with 11 flagellomeres); (3) missing: tarsomeres 2-5 of left fore and left middle legs.

Designation of the ♀ paralectotype of Bracon piger  

Labels identical to those of the lectotype except eighth label attached to the polyporus stage with handwriting “20. aout. M.plai: 3”. Paralectotype is in poor condition: (1) micropinned; (2) right flagellum deficient (with 23 flagellomeres); (3) missing: hind pair of legs and right pair of wings; (4) metasoma glued dorsally (to tergites) onto the label with the text (see before); (5) base of left fore wing torned, left hind wing apically deficient.

Redescription of the ♀ lectotype of Bracon piger  

LENGTH. Body 4 mm long.

ANTENNAE. Almost as long as body and with 32 antennomeres (left antenna). First flagellomere subcubic, 1.2 times as long as broad, further flagellomeres gradually attenuating so that penultimate flagellomere subcubic, somewhat more than 1.3 times as long as broad ( Fig. 40A View Fig ).

HEAD. In dorsal view ( Fig. 40B View Fig ) less transverse, 1.6 times as broad as long, eye one-fourth longer than temple, temple rounded, occiput weakly excavated. Eye in lateral view nearly 1.5 times as high as wide, temple a bit wider than eye ( Fig. 40C View Fig , see arrows). Horizontal diameter of oral opening somewhat longer than shortest distance between opening and compound eye ( Fig. 40D View Fig ). Head polished and hairy.

MESOSOMA. In lateral view 1.3 times as long as high, polished. Notaulix distinct. Propleura in lateral view concave, ventrally elevated and here weakly carinated ( Fig. 40E View Fig , see arrow). Fore pair of coxae somewhat flattened ( Fig. 40F View Fig ; cf. Figs 10 View Fig and 16 View Fig in Achterberg 1985: 171, 173). These latter two features are subgeneric ones. Propodeum polished.

LEGS. Hind femur 3.3 times as long as broad distally ( Fig. 40G View Fig ). Claw more downcurved than usually, its basal lobe large and apically truncate ( Fig. 40H View Fig ).

WINGS. Forewing slightly longer than body. Pterostigma ( Fig. 40I View Fig ) fairly wide, 2.5 times as long as wide and issuing r proximally   from its middle, r somewhat   shorter than width of pterostigma; second submarginal cell long, 3-SR 1.5 times as long as 2-SR, SR1 faintly bent, nearly 1.6 times longer than 3-SR and reaching tip of wing ( Fig. 40I View Fig ). First discal cell usual in form, 1-M twice longer than m-cu, 1-SR-M just bent and nearly 1.4 times longer than 1-M ( Fig. 40J View Fig ).

TERGITES. First tergite ( Fig. 40K View Fig ) somewhat longer than broad behind, beyond pair of spiracles weakly broadening, margin of scutum finely crenulated, otherwise tergite, together with further ones, polished. Second tergite clearly three times broader behind than long laterally, somewhat shorter than third tergite, suture between them bisinuate and smooth. Hypopygium pointed, ovipositor sheath as long as hind tibia and tarsomeres 1-2 combined (ovipositor invisible) ( Fig. 40L View Fig ).

COLOUR. Antenna, head and mesosoma black. Orbit rusty, palpi blackish. Metasoma yellow, fore half of scutum (of first tergite) black. Legs black, hind pair of tibiae basally brownish. Wings brown fumous, pterostigma and veins brown.

The ♀ paralectotype is quite similar in every respect to the lectotype, hence needless to redescribe.

Variable features of the ♀ (127 ♀♀)

Body 3.5-4.5 mm long. Antenna with 26-33, usually with 29-31, antennomeres. Flagellomeres 1.3-1.4(- 1.5) times as long as broad. Head in dorsal view 1.6-1.68 times, exceptionally 1.7-1.73 times ( Fig. 41A View Fig ), as broad as long, eye one-fifth to one-fourth longer than temple. Propleura in lateral view either blunt

( Fig. 40E View Fig ) or stronger ( Fig. 41B View Fig ). Hind femur 3.2-3.4 times, usually 3.3 times, as long as broad. First tergite as long as broad ( Fig. 41C View Fig ) to somewhat longer than broad behind ( Fig. 40K View Fig ).

Deviating features of the ³ (51 ³³)

Similar to the ♀. Body 3.5-4.2(-4.5) mm long. Antenna with 25-36, usually 27-32, antennomeres. Flagellomeres (1.3-)1.4-1.5 times as long as broad. Head in dorsal view 1.6-1.7 times as broad as long ( Figs 40B View Fig ; 41A View Fig ). Prosternum as in ♀ (cf. Figs 40E View Fig ; 41B View Fig ). First tergite somewhat longer than broad behind ( Fig. 40K View Fig ), usually as long as broad behind ( Fig. 41C View Fig ). Metasoma fairly frequently more or less black.
