• ABSTRACT. The present paper offers information about six Neotropical Gonatopodinae. The males of Esagonatopus angelicus Virla and fidalgoi Virla are described, these two species were known previously only on the basis of female specimens. A key for the identification of the males of the Neotropical species of Gonatopus Ljungh is given. A gynander specimen of Gonatopus desantisi Olmi is described and the geographical distribution of this species enlarged. The hosts of Gonatopus lauti Virla are quoted for the first time. Gonatopus contortus Olmi and G. Fritzi (Olmi) are the first species of Dryinidae known for Mendoza province (Argentina).

KEY WORDS. Dryinidae. Gonatopodinae. Neotropic Region. Gynander. Argentina.

• RESUMEN. Datos ineditos sobre Gonatopodinos neotropicales, con des­ cripcion de un especimen ginandromorfo (Hymenoptera: Chrysidoidea: Dryinidae). En la presente contribucion se brinda informacion acerca de seis gonatopodinos neotropicales. Se describen por primera vez los machos de Esagonatopus angelicus Virla y Gonatopus fidalgoi Virla, especies que eran conocidas solo a traves de ejemplares hembra; se aporta una clave pa­ ra la identificacion de los machos de las especies neotropicales del genero Gonatopus Ljungh. Se describe un ejemplar ginandromorfo de Gonatopus desantisi Olmi y se amplfa la distribucion geografica de esta especie. Se men­ cionan por primera vez las especies que sirven de huespedes de Gonatopus lauti Virla y se registra la ocurrencia de la familia Dryinidae en la provincia de Mendoza (Argentina), a traves de Gonatopus contortus Olmi y G. Fritzi (Olmi).
