Designation of the ♀ lectotype of Bracon longicollis  

(First label, printed) “ Coll. Wesmael ”; (second label, printed) “2033”; (third label) “ Braco longicollis   mihi ♀ (handwritten) “dét. C. Wesmael ” (printed); (fourth label, printed red) “ Type ”; fifth label is with the locality “ Belgique / Liège / M. Robert ” and the sixth label is the lectotype card (fifth and sixth labels were attached by me). Lectotype is in good condition: (1) micropinned on a fairly thick pin, pin itself in polyporus stage; (2) right flagellum missing; (3) hind half of mesoscutum invisible because here pierced.

Designation of the eight ♀ and two ³ paralectotypes of Bracon longicollis  

The labels are similar to those of the lectotype except the third Wesmael’s det.-label of five ♀♀ and two ♁♁, they are with the name “ Braco longicollis   mihi ♀ var. 1.” Female paralectotypes are in fairly good condition: (1) micropinned like the lectotype; (2) three ♀ paralectotypes named by Wesmael as Braco longicollis   : flagelli missing of two ♀♀, left fore wing missing of one ♀, left flagellum intact of one ♀ (with 32 antennomeres); (3) three ♀ and one ♁ paralectotypes named by Wesmael as Braco longicollis   var. 1. (however, not representing the variety: propodeal carina present, i.e. not true varieties): left flagellum of one ♀ missing, right flagellum deficient; two ♀♀ and one ♁: one flagellum each intact (two ♀♀ with 26 and 27, one ♁ with 30 antennomeres, respectively), one flagellum each either missing or deficient; left hind leg of one ♀ missing; (4) two ♀ and one ♁ named by Wesmael as Braco longicollis   var. 1. (true varieties): one ♀ with intact pair of flagelli (28 antennomeres), one ♁ with intact left flagellum (29 antennomeres) and right fore (except coxa + first trochanters) and left hind legs (except coxa + first trochanter) missing, one ♀ with missing (left) and deficient (right) flagelli, right fore leg (except coxa) missing. Male paralectotypes are in good (one ♁) and fairly poor (one ♁) condition: micropinned like the ♀ types, one ♁ with intact flagelli (30 antennomeres), one ♁ (true “var. 1.”, in poor condition) with left flagellum intact (29 antennomeres), right flagellum deficient, right fore and left hind legs (except coxa and first trochanter) missing, wings also missing.

Designation of the ♀ lectotype of Bracon brevicauda  

(First label, printed) “V.G.”; (second label attached by me) “ Sweden ” (printed) “Vestergötland” (my handwriting); (third label with red frame, handwritten) “brevicauda”; fourth label is my lectotype card, fifth label is with the actual name B. longicollis Wesmael   given by me. The lectotype is in very poor condition: (1) pinned by mesoscutum; (2) missing: head, metasoma, wings (except left hind wing), right three legs (except middle coxa).

Taxonomic remark

The lectotype specimen is identifiable (or recognisable) by the smooth propodeum with a mediolongitudinal carina characteristic to B. longicollis   .

Designation of the ♀ lectotype of Bracon crassicauda  

( First label, handwritten) “Ört.”; (second label attached by me) “ Sweden ” (printed) “Örtofta nära Lund” (my handwriting); (third label with red frame, handwritten) “crassicauda”; fourth label is my lectotype card; fifth label is with the actual name B. longicollis Wesmael   given by me. -- Lectotype is in fairly

good condition: (1) glued on a small pointed card by coxa 2-3 and ventral side of metasoma; (2) head glued on the first label; (3) right flagellum missing, left flagellum damaged (i.e. with five flagellomeres).

Taxonomic remark

Lectotype is similar to B. longicollis Wesmael   , medio-longitudinal carina of propodeum indistinct.

Designation of the ♀ lectotype of Bracon subcylindricus  

(First label, printed) “Coll. Wesmael”; (second label, printed) “2035”; (third label) Braco subcylindricus   mhi ♀ (handwritten) “dét. C. Wesmael” (printed); (fourth label, printed red) “Type”; fifth label is with the locality “ Belgique / Bruxelles / leg. Wesmael”; sixth label is the holotype card, seventh label is with the actual name B. longicollis Wesmael   (labels 5-7 were attached by me). -- Holotype is in very poor cndition: (1) micropinned by mesosoma, pin fairly thick; (2) head and metasoma glued on the elderpith stage; (3) both antennae deficient, right flagellum with 16 and left flagellum with 23 flagellomeres; (4) ovipositor sheath broken in two parts glued also on the stage.

The following species-names are also junior synonyms of B. longicollis   (details see in Papp 2008: 1774, Shenefelt 1978: 1639, Telenga 1936: 242): B. depressiusculus Szépligeti, 1904   , B. firmus Ruthe   in litt., (?) B. ramosus Niezabitowski, 1910   , B. neglectus Szépligeti, 1904   , B. rugulosus Szépligeti, 1901   , B. spurnensis Hincks, 1951   and Baryproctus niger Voinovskaja-Krieger, 1930   . B. rugulosus Szépligeti   was treated (Papp l.c.) as valid species. Repeatedly examined the long series of B. longicollis   I admit that the synonymization of B. rugulosus   with Wesmael’s senior name B. longicollis   is the reasonable taxonomic point of view (as I did it previously Papp 1969b: 200). This species is highly variable considering the measurements of its head (in dorsal view), alar venation, tergites 1-3, the size and strength of the sculpture of tergites 1-4(-5) and the colour pattern of body. The designations, depositories etc. of the types of B. depressiusculus   , B. neglectus   , B. rugulosus   and B. spurnensis   are mentioned in Papp 2008: 1774.

Bracon longicollis var. depressiusculus (Szépligeti)  

Originally the taxon depressiusculus   was described by Szépligeti as a species of the genus Bracon ( Szépligeti 1904: 182)   . A revision of the Bracon   species by Thomson led to the recognition that the taxon depressiusculus   represents but a variety of the species of B. longicollis ( Papp 1969b: 200)   . This taxonomic assignment is accepted as a deliberate standpoint (contrary to that by Papp 2004: 173), subsequently the distinction of the variety is presented:
