Designation of the ♀ holotype of B. laetus View in CoL

(First label, printed) “ Coll. Wesmael ”; (second label, printed) “2025”; (third label) “ Braco / Laetus mihi ♀ ” (handwriting) “dét. C. Wesmael ”; (fourth label, printed red) “Type”; (fifth label) “ Belgique ” (printed) / “Liège/ leg. Carlier ” (handwriting); sixth label is the holotype card and seventh label is with the actual name B. intercessor var. laetus (Wesmael) (sixth and seventh labels attached by me). - Holotype is in good condition: (1) micropinned, pin fairly thick, i.e. hind half of mesoscutum and prescutellar furrow invisible; (2) left flagellum deficient: with ten antennomeres.

UZBEKISTAN: 1 ♀. IRAN: 3 ♀♀ + 1 ♁ from two localities. KOREA: 1 ♀. CHINA: 1 ♀.

Taxonomic remarks

1) Considering the variability of B. intercessor I quote my previous relevant note ( Papp 2008: 1787): “ Br. intercessor is a highly variable species viewing its body length, several corporal measurements, sculpture of tergites and colour pattern. This variability is well indicated by the fact that different deviating forms were described as many as twenty species by a few authors (mostly by Szépligeti: Papp 2008: 1786-1787). The Nees Collection (braconids etc.) was destroyed at the end of the Second World War; in the case of the species B. intercessor is particularly needed the designation of the neotype to promote its unambiguous specific distinction from its nearest allies.”

2) The species described by Wesmael (l.c.) under the name B. laetus is a light-coloured (or albanic) deviation of the nominate form ( B. intercessor ) and received the new status B. intercessor var. laetus (Wesmael) syn. nov. and comb. nov. This variety is identical with the junior variety names B. intercessor var. concolor Fahringer, 1927 syn. nov., B. intercessor var. elegans ( Szépligeti, 1901) and B. intercessor var. subtilis ( Szépligeti, 1901) (cf. Papp 2004: 152, 2008: l.c.).

3) Distinction of B. intercessor var. laetus from the nominate form:

1 (2) Head in dorsal view transverse, 1.9-2 as broad as long ( Fig. 59H View Fig ). Hind femur slightly thick, 3.1-3.2 as long as broad medially ( Fig. 59I View Fig ). Ground colour of body testaceous, black pattern on mesosternum and propodeum medially. Coxae 2-3 testaceous. Pterostigma yellow .................................................. ............................................................................................ B. intercessor var. laetus ( Wesmael, 1838)

2 (1) Head in dorsal view usually slightly less transverse, 1.7-1.8 times as broad as long ( Fig. 59F View Fig ). Hind femur less thick, 3.3-3.5 times as long as broad medially ( Fig. 59G View Fig ). Body testaceous to reddish yellow with more or less black(ish) pattern on head, meso- and metasoma. Coxae 2-3 usually black(ish). Pterostigma brown ......................................................................... B. intercessor Nees nominate form

Variability

The dark pattern on mesosternum, propodeum and tergites are variable in extent in a few specimens.
