Designation of the ♀ lectotype of Bracon fuscicoxis View in CoL

(First label, printed) “ Coll. Wesmael ”, (second label, printed) “2049”, (third label) “ Braco ♁ ♀ / fuscicoxis mihi” (handwritten) “dét. C. Wesmael ” (printed), (fourth label, printed red) “ Type ”, (fifth label with my handwriting) “ Belgique / Liège / leg. M. Robert ” (above on label) “teste J. Papp / 1987” (reverse on label), sixth label is the lectotype card. - Lectotype is in fairly good condition: (1) micropinned by mesosoma, (2) left antenna apically deficient, i.e. with 23 flagellomeres, (3) left hind wing missing.

Designation of the two ♁ paralectotypes of Bracon fuscicoxis with similar label data to that of the lectotype; first label of one ♁: “13. Juin B 719: 2” (handwritten). One ♁ paralectotype is in fairly good condition: (1) micropinned by mesosoma; (2) flagelli apically deficient; (3) tarsomeres 4-5 of right hind leg missing; (4) right hind wing basally and left hind wing apically damaged. One ♁ paralectotype is in fairly poor condition: (1) micropinned by mesosoma; (2) right flagellum apically deficient; (3) fore pair of legs and right middle leg (except coxae + trochanters) missing.

LENGTH. Body is 3.6 mm long.

ANTENNAE. About as long as body and (right antenna) with 29 antennomeres, left antenna apically deficient and with 25 antennomeres. First flagellomere three times and penultimate flagellomere 1.6 times as long as broad.

HEAD. In dorsal view ( Fig. 12A View Fig ) transverse, 1.85 times as broad as long, eye 1.75 times as long as temple, temple rather receded, occiput weakly excavated. Oral opening usual in size, its horizontal diameter as long as shortest distance between opening and compound eye ( Fig. 12B View Fig ). Head polished, face laterally just coriaceous.

MESOSOMA. In lateral view 1.2 times as long as high. Propodeum polished with a medio-longitudinal carina, laterally from carina subrugulose ( Fig. 12C View Fig ).

LEGS. Hind femur 3.8 times as long s broad somewhat distally ( Fig. 12D View Fig ). Claw of hind tarsus downcurved, basal lobe small ( Fig. 12E View Fig ).

WINGS. Forewing as long as body. Pterostigma ( Fig. 12F View Fig ) 3.3 times as long as wide and issuing r from its middle, r 0.75 times as long as width of pteriostigma. Second submarginal cell less long, 3-SR 1.25 times as long as 2-SR, SR1 1.8 times length of 3-SR, straight and reaching tip of wing and 1-R1 1.5 times as long as pterostigma. First discal cell subquadrate, 1-M 1.5 times as long as m-cu, 1-SR-M bent and 1.4 times as long as 1-M ( Fig. 12G View Fig ).

Temple in dorsal view slightly less receded ( Fig. 12I View Fig ). Face nearly entirely and finely coriaceous. Propodeum medially rugo-rugulose ( Fig. 12J View Fig ). First tergite long, 1.2 times as long as broad behind, beyond pair of spiracles parallel-sided; second tergite almost entirely rugulose ( Fig. 12K View Fig ), third tergite antero-medially subrugulose-uneven. Ground colour of metasoma yellow (1 ♀).

Variable features of both sexes ( Figs 12J View Fig ; 16G View Fig )

Body 3-3.6 mm long. Antenna with 28-36 antennomeres; flagellomeres rarely long, penultimate flagellomere twice as long as broad. Propodeum medially rugo-rugulose ( Fig. 12J View Fig ). First discal cell long as in Fig. 16G View Fig . Pterostigma wide, 2.7-2.9 times as long as wide. Ovipositor sheath somewhat shorter than hind tibia. Tegula yellow. Metasoma nearly entirely yellow.

Taxonomic position

Within the subgenus Glabrobracon the species Bracon fuscicoxis is nearest to B. nigriventris Wesmael (Palaearctic Region, in Europe frequent to less frequent), the two species are distinguished by the following key features:

1 (2) Temple in dorsal view rather receded ( Fig. 12A View Fig ). First tergite evenly broadening posteriorly ( Fig. 12H View Fig ). Propodeum with a medio-longitudinal carina ( Figs 12C, J View Fig ). Hind femur 3.8 times as long as broad medially ( Fig. 12D View Fig ).Tergites 2-3 reddish yellow, second tergite antero-medially with black macula, legs yellow. ♀: 3-3.6 mm, ♁: 3.1-3.2 mm ................................................ B. (Gl.) fuscicoxis Wesmael, 1838

2 (1) Temple in dorsal view rounded ( Fig. 28A View Fig ). First tergite beyond pair of spiracles subparallel-sided ( Fig. 28H View Fig ). Propodeum polished, only above lunule with short rugae ( Fig. 28C View Fig ). Hind femur 2.8-3 times as long as broad distally ( Figs 28D, I View Fig ). Tergites 1-2 vivid brownish yellow, legs brownish yellow. ♀ ♁: 3-3.4 mm ........................................................................................ B. (Gl.) nigriventris Wesmael, 1838
