( Figs. 23–24 )

Odontocera dorsalis Loew, 1863: 54 .

Cerodontha dorsalis, Melander, 1913: 249 ; Frick, 1952: 399; 1959: 396; Spencer 1969: 143; 1981: 174; Spencer and Steyskal 1986: 91; Boucher 2002: 5.

Cerodonta dorsalis, Becker, 1920: 212 .

MNHN specimens. Ecuador: Casitagua, alt. 3500 m, P. Rivet 1903 (1 ♀).

Additional material examined. Jamaica: Blue Mtn. Whitfield Hall, 4200 ft, 10.x.1988, T.A. Wheeler, swept at roadside ( 19 ♂; 16 ♀: LEM).

Host plants. This species has been reared from multiple species of Poaceae .

Comments. Although Becker (1920) listed only male specimens, the specimen examined is a female. Cerodontha ( C.) dorsalis is easily distinguished from other Cerodontha ( Cerodontha) by the absence of acrostichal setulae and the presence of only one notopleural seta. It is widespread in the Nearctic and Neotropical regions including Central America, the Caribbean ( Dominica, Puerto Rico, Jamaica), Peru, Ecuador, Colombia, and Brazil ( Sasakawa 1992c, Boucher 2002).
