Eucoilid Parasites of Agromyzid Leafminers in Hawaii (Hymenoptera: Cynipoidea)

Abstract

Keys and taxonomic descriptions are provided for Eucoilidae associated with agromyzid leafminers in Hawaii. Four genera of such eucoilids are represented in Hawaii: Gronatoma Forster with three species, two of which are described as new: Disorygma Forster and Ganaspidium Weld with one species each, and Weldia Yoshimoto, an endemic complex, the species of which are not treated in this paper. The Ganaspidium species previously determined as G. hunteri (Crawford) was found to be an undescribed species, and the name Ganaspidium utilis is here proposed for it. Two new combinations are proposed: Disorygma pacifica, for Cothonaspis pacifica Yoshimoto and Gronotoma micromorpha for Eucoilidea micromorpha Perkins. Eucoilidea rufula Yoshimoto is placed as a junior synonym of Gronotoma micromorpha (Perkins).
