N2 - Eight sexual mosaic offspring of Zizina emelina (Lepidoptera: Lycaenidae) were obtained from females infected with male-killing Wolbachia (wEmeTn2), though they were mostly dead at the stage of pharate adult. Uninfected females or females infected with another strain of Wolbachia (wEmeTn1) produced no mosaics. Therefore, the occurrence of these sexual mosaics was associated with wEmeTn2 infection. In sexual mosaics, the ventral and dorsal parts of genitalia differentiated independently into male-specific and female-specific formations, respectively, i.e., the ventral part of abdominal segment IX may have tendencies to retain male structures, while the dorsal parts of abdominal segments IX and X possess female structures. More than two pairs of ill-developed valvae were observed in several individuals in a deep pouch. The presence of additional valvae would mean that the segment IX or the ventral phallic lobe is at least partly duplicated.
