[Vol. 95 
The morphological terminology used in this paper is mostly that 
of Shaw (1985, 1987) and van Achterberg (1974). Microsculpture 
terminology is that of Harris (1979). Flagellomeres, from base to 
apex, are abbreviated as FI through FI 3. 
Genus Betelgeuse Shaw, new genus 
(Figs. 1-3) 
Type species: Betelgeuse aztecus Shaw, n. sp. 
Etymology: Following greek mythology, the constellation of 
Orion is depicted on astronomical charts as a sword-bearing hunter. 
Because females have a conspicuous sword-like ovipositor, this 
genus is named for the star Betelgeuse (pronounced “beetle-juice”), 
which is part of the constellation of Orion. The name is masculine. 
Description: Head (Fig. 2) transverse, in dorsal view 2.3X 
broader than long; surface sculpture coarsely and evenly rugose; 
eyes elongate oval, not bulging anteriorly beyond frons; eyes in 
anterior view distinctly converging ventrally; shortest inter-ocular 
distance 2X clypeus width; minute ocular setae present; median 
frontal carina weakly present, extending from midpoint of face to 
between antennal insertions; inter-antennal distance 3.25X socket 
width; scrobes not protuberant; scape elongate, gradually curved, 
gradually wider apically; scape length 4X width at apex; pedicel 
somewhat globose; flagellum 13-segmented, considerably shorter 
than body length; F1-F5 longer than wide, gradually wider apically, 
somewhat flattened, forming serrations antero-laterally, each serra- 
tion terminating apically in a sharp point and a single long seta; FI 
3X wider than apical width, F2-F5 each relatively shorter than 
preceding flagellomere; F6-F12 each compact, about as long as 
wide, segments gradually slightly thicker apically, each with a single 
long seta projecting dorso-apically; apical flagellomere 2X as long 
as wide, apically pointed; ocellar triangle small, distance between 
lateral ocellus and eye 4X distance between lateral ocelli; occipital 
carina complete; malar space short, slightly less than 1/4 eye height; 
malar suture indistinct; facial setae minute, not obscuring face; 
lower clypeal margin truncate; mandibles when closed overlapping 
for slightly less than half mandible length; maxillary palpus 5- 
segmented; labial palpus 2-segmented. 
Mesosoma with surface sculpture entirely coarsely rugose to 
rugo-punctate; notaulus and sternaulus indistinct from general
