rugose sculpture; scutellar furrow 10-foveate, cross-carinae present; 
anterior margin of scutellar furrow carinate; propodeum rugo- 
areolate; propodeal impression present, as deep as basal width of 
petiole; postero-lateral corners of propodeum developed as promi- 
nent tubercles; petiolar notch short, not extending past metacoxal 
cavity; hind leg except tarsus coarsely granular; metafemur length 
4.25X maximum width; tarsal claw simple. 
Wings as in Fig. 3; stigma large, nearly semi-circular; basal vein 
gradually curved; second intercubitus absent; second cubital ab- 
scissa present; discoideus present; brachius present; first intercubitus 
present; radius reaching wing margin slightly before wing apex, 
radial cell longer than stigma; radius complete to wing margin, but 
more weakly sclerotized apically; metacarpus present, but very 
weakly sclerotized; recurrent vein present; subdiscoideus present; 
first cubital abscissa absent; nervulus postfurcal, bisecting disco- 
cubital cell; medius present; submediella present; nervellus present; 
costella present; radiella and cubitella present as weak infumation. 
Metasoma with petiole not fused ventrally, smooth dorsally, 
rugose laterally, apex 4X broader than base, about 3/4 as long as 
metasoma beyond petiole excluding ovipositor; glymma absent; 
dorsope absent; petiolar spiracles near middle of petiole, moderately 
prominent; syntergum 2+3 shorter than 3/4 length of metasoma 
beyond petiole excluding ovipositor, several following segments 
exposed; sides of syntergum 2+3 not overlapping ventrally; lateral 
fold of syntergum 2+3 present; suture between terga 2+3 present 
laterally; ovipositor 0.94X as long as metasoma; sheaths shorter, 
about 0.56X as long as metasoma. 
Diagnosis: In the key to genera of Euphorinae of the world by 
Shaw (1985) Betelgeuse will run to couplet 29, but will not key 
further because the scape configuration does not match either of the 
two alternatives at that point. In the identification manual for North 
American genera of Braconidae (Marsh et. al 1987) Betelgeuse will 
run to couplet 212, where it keys out near Ecclitura Kokujev from 
which Betelgeuse can be distinguished by its distinctive serrate 
antenna. Indeed, it can be distinguished from any other braconid 
genus by this character alone. 
Phylogeny: The phylogeny of euphorine genera was reviewed by 
Shaw (1985, 1987). Because the fore wing lacks the first segment of
