Canadian Species ofLatalus(Homoptera: Cicadellidae)

Abstract

Three North American species ofLatalusand four ofQuontuswere listed by Oman (1999). Two of these are conspecific with a third and three new species are described below. Two of the previously described species have not been found in Canada and are not discussed here. They areDeltocephalus latidensSanders and DeLong (1919, p. 234) andLatalus uncinatusBeamer and Tuthill (1934, p. 6). They are distinguished by genitalic characters described in the original descriptions.QuontusOman (1949) is treated here as a synonym ofLatalusDeLong and Sleesman (1929), as the distinctions given by Oman (1949) intergrade and do not always hold good. Canadian species ofLatalusapparently inhabit grasslands. The best specific characters are in the internal male genitalia, though the female seventh sternite shows valid characters in some species.
