Cirrospilus sp. A (not C. vittatus )

NEW STATE RECORD

When blister galls began forming on lemon-scented gum tree foliage in Aiea, Oahu, leaves were collected and held for the emergence of potential gall-forming insects. What was discovered turned out to be an assemblage of about six separate species. Additional samples from Honolulu produced similar results. All samples of Oahu Corymbia citriodora blister galls, produced Cirrospilus sp. A , Epichrysocharis burwelli (presumed gall former), and four additional species of unidentified Hymenoptera (Chalcidoidea) . Cirrospilus sp. A is possibly a parasitoid species; however, it is unknown which of the five other species found in the leaf material may be its host. C. vittatus is the only other established species of Cirrospilus recorded in Hawaii (Kauai, Maui, and Oahu) but is known to attack Cremastobombycia lantanella ( Lepidoptera : Gracillariidae ). The Cirrospilus reared from C. citriodora blister galls can be described as yellow, slender-bodied, highly patterned, with a somewhat iridescent thorax. Also see Epichrysocharis burwelli .

? Closterocerus sp. A (not C. utahensis )

NEW STATE RECORD

Eucalyptus sp. foliage with blister galls collected from West Maui was held for the emergence of gall formers. At least two species of Tetrastichinae wasps emerged- a possible Closterocerus sp. A and an Ophelimus sp. A . According to La Salle (2005 pers. comm., 14 June), this possible Closterocerus sp. A is most likely a parasitoid of the Ophelimus sp. A , which is probably the gall former on this Eucalyptus sp. material. On Oahu, Closterocerus utahensis has been recorded attacking species of Liriomyza ( Diptera : Agromyzidae ). Also see Ophe-
