| Abstract: Two new genera of East African Acrometopini are erected: the monotypic Peronurella n. gen. with P. centralis n. sp. from Miombo woodlands in central Tanzania, and Tenerasphaga n. gen. for a morphological uniform group of species formerly included in Horatosphaga, T. chyuluensis n. sp., T. mbulu n. sp. T. nanyuki, T. nuda n. comb, T. meruensis n. comb, T. tenera n. comb and T. bazeletae n. comb. Additional species are described in the genera Altihoratosphaga, Lamecosoma and Peronura. Keys to African genera of Acrometopini and species of the genus Tenerasphaga are provided. We review the male calling songs and the morphology of the acoustical apparatus and discuss how the morphology of the stridulatory files explains the complicated song patterns and elements. All Acrometopini species showed a plesiomorphic karyotype with a diploid chromosome number of 2n = 31 and a X0 sex chromosome system in males. |
