To the knowledge of the African fauna of the family Issidae (Hemiptera, Auchenorrhyncha: Fulgoroidea) with descriptions of new genera and new species

Аннотация

Two new genera and two new species of the family Issidae are described from Cameroon and the Republic of the Congo; two new species of the genus Issus Fabricius are also described from Libya (the Barka Peninsula) and Morocco; a new species of the genus Kovacsiana Synave is described from northeastern Nigeria. Supplemented descriptions of Chimetopon camerunensis Schmidt, 1910, Hemisobium hammersteini Schmidt, 1911, and Kovacsiana abyssinica Synave, 1956 are provided based on examination of the type specimens. A new subtribe is erected in the tribe Issini for accommodation of the genera Chimetopon Schmidt, 1910, Cascaruna gen. n., and Ikonza Hesse, 1925. Hysteropterum horvathi Melichar, 1906 and H. vibex Melichar, 1906 are transferred to the genus Kovacsiana. Issus acuminatus Lethierry, 1876 is placed in synonymy to I. patruelis Stål, 1861 and transferred to the genus Semissus Melichar, 1906. The faunal species-richness and pattern of the distribution of the family Issidae in Africa are briefly discussed.
