Description of the head

The description is based on a ♀ quite identical to the ♀ lectotype (taken in Hungary, Makó, 12 July 1950, ex larva Dypessa ulula Borkhausen, Lep. Cossidae , leg. et educ. Dr. B. Nagy).

Antenna short, as long as head + mesosoma + tergites 1-2 combined and with 32 antennomeres. First flagellomere 1.4 times and penultimate flagellomere 1.2 times as long as broad, middle flagellomeres cubic and last 7-8 flagellomeres somewhat longer than broad. Head in dorsal view ( Fig. 10A View Fig ) transverse, almost 1.9 times as broad as long, eye somewhat protruding and almost 1.3 times length of temple, temple moderately rounded, occiput excavated. Oral opening fairly large, its horizontal diameter onethird longer than shortest distance between opening and compound eye ( Fig. 10B View Fig ). Head polished.

Variable features of the ♀ (32 ♀♀) ( Figs 10 View Fig I-J; 11A-E)

Body 3-4.3, usually 3.5-4, mm long. Antenna with 26-33 antennomeres. Head in dorsal view less transverse, 1.7-1.85 times as broad as long, eye 1.2 to 1.4 times length of temple ( Fig. 11A View Fig ). Hind femur usually 2.5 times, less usually 2.8-2.9 times, as long as broad medially ( Fig. 10 View Fig I-J). Pterostigma 2.7-3 times as long as wide, 3-SR 1.25-1.4 times as long as 2-SR ( Fig. 11B View Fig ). First discal cell more low to low, 1-M 1.4-1.6 times length of m-cu ( Fig. 11C View Fig ). First tergite beyond spiracles sometimes just broadening ( Fig. 11D View Fig ). Tergites 2-3 usually rather longitudinally rugose to rugulose ( var. curiosus Szépligeti ; Fig. 11E View Fig ), third tergite sometimes almost smooth ( var. lautus Szépligeti ) or sculpture varying to nearly smooth tergites 2-3, i.e. rugo-rugulosity restricting around medio-basal field of second tergite. Vertex, mesoscutum, propodeum and first tergite with black pattern of variable extent. Tergites 2-3(4) rarely blackish to back medially.

Description of the ³ (47 ³³) ( Figs 10 View Fig I-J; 11F-I)

Similar to the ♀. Body 2.8-3.5 mm long. Antenna about as long as body or somewhat shorter and with 30-35 antennomeres. Flagelloneres distally clearly longer than broad. Head in dorsal view ( Fig. 11F View Fig ) 1.6-1.7 times as broad as long. Hind femur 2.6-2.9 times as long as broad medially ( Fig. 10 View Fig I-J).

Taxonomic position

Within the subgenus Lucobracon the species Bracon fortipes is nearest to B. erraticus Wesmael (Palaearctic Region) viewing their wide first tergite and thick hind femur, the two species are separated by the following key features:

1 (2) Second tergite rugose, third tergite rugulose-subrugulose ( Fig. 8J View Fig ). Claw clearly downcurved ( Fig. 8G View Fig ). Forewing: second submarginl cell relatively less wide (as usually), 3-SR at most 1.3 times length of 2-SR ( Figs 8H View Fig ; 9D, G View Fig ). Pterostigma brown ( Figs 8H View Fig ; 9D, G View Fig ), ground colour of body black with more or less reddish yellow to yellow pattern. ♀ ♁: 2.5-4.5 mm ........ B. (Lu.) erraticus Wesmael, 1838

2 (1) Tergites 2-3 longitudinally striated ( Fig. 10H View Fig ) or longitudinally rugose-rugulose ( Fig. 11E View Fig ). Claw less downcurved ( Fig. 10E View Fig ). Forewing: second submarginal cell relatively wide, 3-SR (1.25-)1.4 times length of 2-SR ( Fig. 10F View Fig ). Pterostigma light brownish ( Fig. 10F View Fig ), ground colour of body reddish yellow with less dark pattern. ♀: (3-) 3.5-4.3 mm, ♁: 2.8-3.5 mm ............... B. (Lu.) fortipes Wesmael, 1838

By its yellowish reddish ground colour B. erraticus var. confinis (Szépligeti) superficially resembling B. fortipes ; however, they are distinguished by the following key features:

1 (2) Claw less downcurved ( Fig. 10E View Fig ). Tergites 2-3 longitudinally striate ( Fig. 10H View Fig ). Pterostigma yellow. ♀ ♁: 2.8m- 4.3 mm .................................................................. B. (Lu.) fortipes Wesmael, 1838

2 (1) Claw more downcurved ( Fig. 8G View Fig ). Tergites 2-3 rugose-rugulose ( Fig. 8J View Fig ). Pterostigma opaque brown, exceptionally yellow. ♀ ♁: 2.5-5.5 mm ........ B. (Lu) erraticus var. confinis ( Szépligeti, 1901)
