The zoysiagrass billbug, Sphenophorus venatus vestitus CHITTENDEN (Coleoptera: Curculionidae), which is inferred to be introduced into Japan from the United States, has been found occurring in Fukuoka, Hyôgo and Tokyo Prefectures since the first discovery at a golf course in Okinawa Prefecture in 1979. Five adults (2 females and 3 males) of this species were captured by using pitfall traps at the bank of Yamato River in Osaka and Nara Prefectures in 1986, 1988 and 1989 (Table 1). This may be the first discovery of this species in both prefectures and the second record from the river bank after the record from the Tama River in Tokyo.
