Afrachilini trib. nov. of Achilidae from Southern Africa (Hemiptera: Fulgoromorpha: Fulgoroidea)
Abstract
This paper describes a new species of Afrachilus Fennah, 1965 (Hemiptera: Fulgoromorpha) – Afrachilus montanifynbosensis sp. nov., from the tribe Afrachilini trib. nov., subfamily Myconinae, found in the West Cape of South Africa. This region is one of the Earth’s biologically most diverse areas, also characterized by the phylogenetic antiquity of its invertebrates. A brief discussion is provided on the host plant records of the Afrachilini trib. nov. Morphological peculiarities and diagnostic features of the new tribe are discussed, especially a modification of the head capsule with a subdivision of the frontal area, which is unique in Achilidae, the presence of platellae on the first two metatarsomeres, open cell C1 on tegmen, and the presence of two terminals of CuA on the hind wing, as well as the presence of a subvaginal plate in females, which is another peculiar feature not commonly present among Achilidae. Further distributional data on Achiplecton stilleri (Achiplectini) are provided herein.
