Radialis virtually absent or showing as a small sclerotized prolongnation at tip of stigmalis but not developed as a spurious vein; pronotal shoulders very prominent, angular and marginated outwardly by a longitudinal keel; marginalis at least two-thirds as long as its distance from the basalis (fig. 104). (scape shorter than pecicel plus flagellum 1)
Radialis better developed, either showing as a very long, spurious vein or, if short, then the marginalis is much less than two-thirds its distance from the basalis
