Material examined. HOLOTYPE: male, from Lonicera hispidula, Alameda Co.   , California, 22.ii.2005, R. Russo     . Paratypes: 2 males, 5 females, 2 pupae, 1 pupal exuviae, and 1 larva, same data as holotype   .

Etymology. This species is named for Ronald A. Russo   in 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 California and other Western States ( Russo   2007).

Distribution. The type specimens were reared from galls found in Alameda Co., California. R. Russo   (in litt.) found similar galls also in Mendocino Co., California.

Life history. Lonicerae russoi   is responsible for a green, leafy rosette bud gall ( Fig. 1 View FIGURES 1 – 3 , 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 mm high by 8 in diameter and the clusters 30 mm in diameter. Individual leaves or bracts covering the galls are about 3 mm wide. White hairs protrude from edges of the bracts and more densely from the center of each gall. The individual larval chambers are 4 mm long by 2 mm in 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 Lonicera   spp. in California ( Russo   2007), including that of L. lonicera   ( Fig. 2 View FIGURES 1 – 3 , this paper; also Fig. 241, Gagné (1989) and plate 236, Russo   (2007)), from L. subspicata   in southern California.
