Two new Species of Cicadulina, China (Homoptera, Jassidae) from the Gambia, West Africa

Abstract

The genus Cicadulina was erected in 1926 (Bull. Ent. Res., xvii, p. 43) to hold C. zeae, a new species injurious to maize in Kenya Colony. Thanks to the kindness of Mr. T. J. Naudé, I have since been able to examine specimens of Balchitha mbila, Naudé, which has been recorded as transmitting the virus of streak disease of maize in Natal. This species is undoubtedly congeneric with C. zeae and differs from typical Balclutha species in the shape of the head and pronotum, and in the venation of the tegmina. It should, therefore, be known in future as Cicadulina mbila, Naudé.
