Designation of the ♀ holotype of Bracon colpophorus View in CoL

(After Papp l.c.) (first label, handwriting) “5.11.”, (second label, printed) “ Coll. Wesmael ”, (third label, printed) “2059”, (fourth label) “ Braco ♀ colpophorus mihi” (handwriting) “dét. C. Wesmael ” (printed), (fifth label with my handwriting) “ Belgique / Bruxelles / leg. Wesmael ” (above on label) “teste J. Papp 1987” (reverse on label), sixth label is the holotype card. Holotype is in fairly good condition: (1) pinned by mesosoma (posterior half of notaulix invisible); (2) both antennae deficient, right flagellum missing, left middle leg (except coxa + trochanter) missing.

Distribution

England, Belgium, The Netherlands, France, Germany, Austria, Hungary, Poland, Romania, Italy and former Yugoslavia ( Shenefelt 1978: 1563; Yu et al. 2005); Russia (European part, Kuznetzk) ( Telenga 1936: 191).

Taxonomic position

The general appearance of B. (Gl.) colpophorus relegates it to the relationship of B. (Gl.) instabilis Marshall ( England, Germany, Bohemia, Bulgaria) and B. (Gl.) obscurator Nees (Palaearctic Region). The distinction of the three species is restricted to a few features; however, of solid specific value as shown (after Papp 1997: 128-129):

1 (2) Temple in dorsal view ( Fig. 2E View Fig ) strongly rounded or fairly constricted. Antenna usually as long as body and with 28-30 antennomeres. Second tergite rather longitudinally rugulose with some striolate elements ( Fig. 2F View Fig ). Ovipositor sheath in lateral view about as long as hind tibia. ♀: 2.2-3 mm ........ ........................................................................................................... B. (Gl.) instabilis Marshall, 1897

2 (1) Temple in dorsal view rounded (i.e. never constricted, Figs 1A View Fig ; 2G View Fig ). Antenna usually more or less shorter than body and with 20-25 antennomeres. Second tergite polished, at most exceptionally and rarely with weak to very weak sculpture medially.

3 (4) Fore wing: CU2 long, 3-SR nearly twice as long as 2-SR, SR1 about one-third to one-and-a-half times as long as 3-SR ( Figs 1E View Fig ; 2D View Fig ). Suture between tergites 2-3 bisinuate ( Figs 1G View Fig ; 2C View Fig ). Ovipositor sheath in lateral view about as long as hind tibia + half basitarsus combined. Legs black, fore femur and tibia almost entirely and tibiae 2-3 basally yellow, reddish yellow. ♀: 2.8-3.2 mm, ♁: 2-2.5 mm ...................................................................................................... B. (Gl.) colpophorus Wesmael, 1838

4 (3) Fore wing: CU2 less long, 3-SR somewhat to 1.5 times longer than 2-SR, SR1 about twice as long as 3-SR ( Fig. 2H View Fig ). Suture between tergites 2-3 almost straight ( Fig. 2I View Fig ). Ovipositor sheath in lateral view about twice and at least 1.5-1.6 times as long as hind tibia. ♀ ♁: 1.7-3 mm, usually 2-2.8 mm ..............................................................................................................
