J. HYM. RES. Vol. 4, 1995, pp. 64-76 Euryischomyia Girault (Hymenoptera: Chalcidoidea: Aphelinidae: Eriaporinae: Euryischiini) Mary Carver Division of Entomology, CSIRO, G.P.O. Box 1700, Canberra, A.C.T. 2601, Australia Abstract. — Types of some Australian Euryischiini described by A. A. Girault have been exam-ined, and compared with other material identified by Girault, together with other reared and collected material of Euryischomyia Girault. Euryischomyia saintpverrei Girault, 1915, syn. nov.; Myiocnema marmorativentris Girault, 1915, syn. nov.; E.fasciata Girault, 1916, syn. nov.; and £. setosa Girault, 1929, syn. nov.; are placed in synonymy with £. flaznthorax Girault & Dodd, 1915; and £. alami Shafee, 1975, syn. nov., (described fom India), is placed in synonymy with E. washingtoni Girault, 1914. A key to the 2 remaining species of Euryischomyia is provided. £. washingtoni and £. flavithorax are redescribed. £. zuasJiingtoni is known as a parasite of pseudococcids, and £. flavithorax as a hyperparasite of psyllids, aphids, coccids and pseudococcids.

Euryischomyia Girault, 1914; and Para-Girault (1930) placed Euryischomyia in syn-myiocnema Girault, 1917. Euryischiini are onymy with Myiocnema.
