Amisega species are characterized by: narrow metanotum, less 
than half as long as scutellum; malar space less than one-eighth eye 
height; underside of head with long narrow fovea on either side of 
midline of genal bridge (= suboral fovea); propodeum without lat- 
eral angles; mesopleuron without oblique mesopleural carina, and 
pronotum without medial groove or anterior and lateral carina. 
Species distinctions in this group are difficult, and color patterns 
tend to be more useful than structural measurements. Unfortu- 
nately, unlike most chrysidids, male Amisega tend to be structurally
