03A078748052FF9876A7F8B2FCC08BE4.taxon	description	Cut eucalyptus branches were stored in plastic bags punctured with # 4 insect pins (to prevent adult escape and to keep material from fast drying). From November 8 – 10, these bags were placed in the lower (fruit / vegetable) section of a refrigerator to stop fungal growth and to possibly stimulate the emergence of adults. Adults started emerging on November 12 and were observed emerging until December 2. About 120 – 130 adults were reared along with two Erythmelus gracilis (Howard) (Mymaridae), which are egg parasitoids and were probably present as contaminants brought in on the twigs. There were high larval and pupal densities present in galls, with adults emerging at the same time. A second infestation was subsequently found at the Los Angeles County Arboretum and Botanical Gardens located in Arcadia (by J. Turney, Los Angeles Co. Dept. of Agricultural Commissioner / Weights & Measures). As yet no adults have emerged from these samples; the larvae were submitted to CDFA to confirm the new location. Subsequent rearings recovered additional species of wasps associated with these galls. The most interesting was the rearing of five males of an Ophelimus species (Eulophidae: Ophelimini). Ophelimus is an unusual Australian genus which contains over 50 described species and many more undescribed. Species have been assumed to always be gall inducers (Bouček 1988), and this is probably the largest group of gall inducing eulophids on Eucalyptus. However actual biology is known for relatively few species, and there is some indication that at least some species are not true gall inducers but are associated with galls in other ways, perhaps as inquilines or even parasitoids (La Salle 2005). The presence of Ophelimus sp. questions the status of the two wasp species associated with blue gum galls in California. Selitrichodes species appear to be mainly parasitoids of gall inducing wasps (Kim et al. 2008), and Ophelimus are predominantly gall inducers. In this case, it appears that these roles are reversed. Further studies to clarify the exact roles of all the species associated with these galls will be of interest. However, it should be pointed out that when this paper was submitted, samples of gall infested E. globulus had produced almost 600 S. globulus, and less than 20 male Ophelimus. Under these circumstances, it is difficult to imagine S. globulus as being anything except the primary gall inducer.	en	Salle, John La, Arakelian, Gevork, Garrison, Rosser W., Gates, Michael W.

03A078748057FF9E76A7FEC6FDA28BAE.taxon	diagnosis	Diagnosis. A key to North American Tetrastichinae genera was provided by La Salle (1994), and keys to all North American Eulophidae genera were supplied by Schauff et al. (1997). In these keys Selitrichodes would key to Baryscapus or Aprostocetus, but can be distinguished by the diagnostic characters given in Kim et al. (2008), and which are repeated below. SMV usually with 2 or 1 dorsal setae. PMV distinct, usually about 0.4 – 0.5 the length of STV. Propodeum without a raised lobe of callus which partially overhangs outer rim of spiracle. Cercal setae short and subequal in length. Mesosternum anterior to trochantinal lobe convex and without a precoxal suture. Malar sulcus generally curved, and gena may be somewhat swollen. All funicular segments subquadrate or slightly transverse. Postmarginal vein distinctly developed, although shorter than stigmal vein. Non-metallic (mainly yellow with black markings). Males (of at least some species) with 3 funicular segments.	en	Salle, John La, Arakelian, Gevork, Garrison, Rosser W., Gates, Michael W.

03A078748057FF9E76A7FEC6FDA28BAE.taxon	description	Selitrichodes species can be distinguished from Baryscapus in that Baryscapus species are all predominantly metallic in coloration, and Selitrichodes species are non-metallic. Selitrichodes can be separated from Aprostocetus in that Selitrichodes species have 1 or 2 setae on the SMV, and the bulk of Aprostocetus species have 3 or more setae on the SMV; the few Aprostocetus species with only 2 setae on the SMV have metallic coloration. The following characters in combination serve to distinguish S. globulus from other described species of Selitrichodes: Color uniformly dark brown, without extensive areas of yellow markings; POL about 3 times as long as OOL; speculum small and open posteriorly; cubital setal line approaching but not reaching basal line; speculum may have a few small setae on underside of wing; antenna with F 1 longer than wide; F 3 subquadrate to wider than long.	en	Salle, John La, Arakelian, Gevork, Garrison, Rosser W., Gates, Michael W.
