With the usual differences from the worker. Pronotum with flat 
dorsal pronotal platform, as seen from above, markedly constricted 
before it joins the inesothorax. Scutellum rounded and bulging 
caudad. Petiolar node broader than in worker, and tending to be 
medially sulcate in front. Scutum irregularly reticulate-punctate, its

Color blackish-brown, gaster dark reddish-brown, legs and an- 
tennae sordid, pale, dull brown; wings hyaline. Mandibles slender, 
each with a weak tooth-like angle apicad of midlength, only slightly 
curved, probably not opposable, tapered to a very acute apex. 
Labrurn broad, the 2 lobes short and separately rounded. 
Antennal scape broader and longer than pedicel, and about as 
broad as the apical antennal segment; segments III through XII 
slender and cylindrical, all longer than scape or pedicel. Pronotum 
forming a flattened, C-shaped platform, something like that of 
female. Mesonotum large and bulging; notauli present but short, 
and not meeting behind to form a V or Y; parapsidal lines present. 
Scutellum bulging, rounded caudad. Propodeal teeth low, subacute, 
with narrow, concave infradental lamellae. Mesokatepisternum and 
a patch on the side of the propodeuin with sculpture effaced, nearly 
or quite smooth and shining. 
Petiole claviform, with low, rounded, scarcely differentiated node 
that is mainly smooth and shining above; spongiform appendages 
reduced to a narrow mid-ventral strip and a fine, cariniform 
posterodorsal collar. Postpetiole broader than long, rounded, 
smooth and shining, with a narrow, posterior collar of transparent 
lamella and an anteroventral spur trimmed narrowly with trans- 
parent lamella. Gaster unadorned at base, smooth and shining, with 
an extremely sparse, inconspicuous sprinkling of tiny, appressed
