The following description is modified from Mason (1981).
Hypopygium very large, medially folded, and striate; ovipositor sheath arising distally on second valvifer, hairy throughout its length and slightly shorter than hind tibia. Tergite I strongly transversely arched above the soft lateral margins (lateroterga), sides weakly to strongly tapering apically, a little, or much, longer than wide; surface of tergite I completely, coarsely rugulose except for a small mediobasal trough; tergite II similarly arched and completely coarsely rugulose to aciculate, subrectangular and 2 or 3 x wider than long; tergum III often partly aciculate and a little longer or a little shorter than II. Anterior corners of tergite I often strongly and characteristically rounded and humped; the posterior horizontal part of first tergite 2-3x longer than the strongly declivous anterior part. Propodeum with a strong complete median carina; surface coarsely rugulose but posterolateral corners shiny and irregularly transcostate; anterior margin of metanotum without small projection or hair-tuft; scutellum coarsely punctate, the sculpture posteriorly (rarely partially) across the polished apical band; mesonotum with strongly marked notauli, the posterior courses of which are defined by markedly coarser sculpture and sometimes depressed grooves; mesopleural furrow nearly horizontal, long, transcostate, and with a dorsal branch; side of pronotum with strong dorsal and ventral grooves. Radius usually curved and strongly slanting outwards, meeting the intercubital at a strong angle, the two veins about equally long or the radius shorter; radius rising about the apical quarter of the stigma; vannal lobe weakly convex and bearing abundant long hairs. Legs rather long and slim, tarsal claws simple. Hosts. As far as known Pyraloidea and Microlepidoptera; larvae solitary. Distribution. This small genus is confined to eastern North America, Mexico, and the Caribbean Region. Remarks. The closest relative may be Hygroplitis which differs in lacking the median striae of the hypopygium and in having a complete second intercubital vein.
