This species is named for Ronald A. Russoin recognition of his contributions to the study of galls of western North America. Formerly Chief Naturalist, East Bay Regional Park District, Alameda and Contra Costa Counties in California, he now resides in Bellingham, Washington. He is the author of Field Guide to Plant Galls of Californiaand other Western States(  Russo 2007).   Distribution. The typespecimens were reared from galls found in Alameda Co., California. R. Russo(in litt.) found similar galls also in Mendocino Co., California.  Life history.  Lonicerae russoiis responsible for a green, leafy rosette bud gall ( Fig. 1, this paper, and plate 238 of  Russo(2007))on  Lonicera hispidula.  Russo (2007)reported that galls usually appear several together at the tips of shoots, but may occur singly also. Individual galls may be 10 mmhigh by 8 indiameter and the clusters 30 mmin diameter. Individual leaves or bracts covering the galls are about 3 mmwide. White hairs protrude from edges of the bracts and more densely from the center of each gall. The individual larval chambers are 4 mmlong by 2 mmin diameter. Larvae were pupating in late February when the galls were found and adults emerged in late February to early March. The gall is one of at least three distinct bud galls on  Loniceraspp. in California(  Russo 2007), including that of  L. lonicera( Fig. 2, this paper; also Fig. 241, Gagné (1989)and plate 236,  Russo(2007)), from  L. subspicatain southern California. 1302807017 2005-02-22 California 10 413 1 California holotype 1302807018 [233,1262,726,751] 2005-02-22 California 10 413 9 5 2 2 California paratype
