Distribution. Costa Rica.

Hosts. Reared as primary parasitoid from Herpetogramma salbialis (Hampson) and Ategumia lotanalisDHJ09 ( Lepidoptera : Crambidae ), and from Calpodes ethlius (Stoll) ( Lepidoptera : Hesperiidae ).

Etymology. Named in honor of Mrs. Anne Smith of Arlington, Virginia, an international lawyer in recognition of her professional base in theories and principles put forward by Hugo Grotius (1583-1645) who established modern international law, and in recognition of her years of vigorous defense of Área de Conservación Guanacaste as a new UNESCO World Heritage Site.
