Diagnosis

The main distinguishing features of this species are as follows (after Huber 1988). Body length (female) 912–1232. Body generally dark brown. Longitudinal sensilla usually present on F3–F8 of the female antenna (F4 rarely lacking sensilla); F1 and F2 usually without sensilla (F2 rarely with 1 longitudinal sensillum). Submedial carinae on the propodeum prominent, uniformly thickened, reaching the dorsellum. Forewing ( Fig. 28 ) hyaline or with a faint uniform brown tinge, and usually with a distinct infumate spot just beyond the stigmal vein; microtrichia of blade absent behind venation except for a few setae behind apex of stigmal vein.

Distribution

Canada (Nova Scotia), Mexico, Honduras (new record), and USA (Arkansas, Arizona, California, Florida, Georgia, Hawaii [new record], Illinois, Kansas, Louisiana, Maryland, Missouri, Mississippi, New York [new record], Pennsylvania, Tennessee, Texas, Virginia, West Virginia [new record]).

Hosts

Graphocephala coccinea (Förster) , G. versuta (Say) , Homalodisca coagulata (Say) , H. liturata Ball , and very likely (although not yet documented) Oncometopia orbona (Fabricius) . This very distinctive species usually attacks mostly the first (early spring) brood of H. coagulata in southern California.
