Abstract.— A new genus and species of the subfamily Entedoninae (Hymenoptera: Eu-lophidae), Callifrons maculata Schauff, Yoshimoto, and Hansson are described based on specimens from Costa Rica, Mexico, and the United States (Florida and Missouri). Cal-lifrons is differentiated from other entedonine genera by the expansion of the upper vertex and frons into two distinct points laterad of the eyes and is considered most closely related to Closterocerus and Omphale. The host is unknown. Key Words: Chalcidoidea, North America, Central America, Eulophidae, Callifrons Introduction: Over the past few years, a major effort has been underway by a group of American, Canadian, and European chal-cid workers to prepare a comprehensive set of keys to the genera of Chalcidoidea for the U.S. and Canada. As part of that work a number of new taxa are being described in most of the major families of chalcids so that the keys will be as up to date as possible. This paper describes a new genus of the subfamily Entedoninae (Eulophidae), mak-ing a name available so that the group can be included in the forthcoming key to eu-lophid genera that will be a part of the larger keys to the genera of the superfamily.
