Light and transmission electron microscopy were used to examine the intracellular endosymbionts of male and female adult glassy-winged sharpshooters. Bacteriomes consisted of paired reddish organs associated with yellow glandular-like structures located in the ventro-lateral anterior portion of the abdomen. Two morphologically distinct bacteria-like organisms were observed in bacteriocytes: one spherical in shape and one larger, highly pleomorphic organism that often appeared elongated. Both tested gram negative, lacked a cell wall and were usually surrounded by three membranes.
