 Remarks. Cybocephalus nipponicus is the only U.S. cybocephalid which has a

sexually dimorphic color pattern (Fig. 4-28). This species, now widely distributed

throughout the eastern U.S., was misidentified as C. binotatus and released in south

Florida in 1998 to combat A. yasumatsui (Anon. 1998; Howard and Weissling 1999) on

sago palms (Cycas spp.). These two species have been confused in the past as evidenced

by Endrody-Younga mixing specimens of C. binotatus (Fig. 4-28) and C. nipponicus

(Fig. 4-29) in the description of C. binotatus in his 1968 monograph of the Palearctic

cybocephalids. He later clarified this in his description of C. nipponicus and a

redescription of C. binotatus (Endrody-Younga 1971a). A male topotype of C. binotatus

was compared to the beetles released in Florida. Two black spots on the yellow

pronotum, a metallic sheen on the elytra, and distinctive male genitalia clearly separate C.

binotatus from C. nipponicus. It was believed that the 1998 release of C. nipponicus

from Thailand was the first introduction of these beetles into the state of Florida (Howard
