Abstract
Two new genera of East African Acrometopini are erected: the monotypicPeronurellan. gen. withP. centralisn. sp. from Miombo woodlands in central Tanzania, andTenerasphagan. gen. for a morphological uniform group of species formerly included inHoratosphaga,T. chyuluensisn. sp.,T. mbulun. sp.T. nanyuki,T. nudan. comb,T. meruensisn. comb,T. teneran. comb andT. bazeletaen. comb. Additional species are described in the generaAltihoratosphaga,LamecosomaandPeronura. Keys to African genera of Acrometopini and species of the genusTenerasphagaare 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.
期刊介绍：
Insect Systematics & Evolution (ISE) publishes original papers on all aspects of systematic entomology and the evolutionary history of both extant and extinct insects and related groups. Priority is given to taxonomic revisions and phylogenetic studies employing morphological and molecular data. ISE also welcomes reviews and syntheses that can appeal to a wide community of systematic entomologists. Single species descriptions, regional checklists, and phylogenetic studies based on few taxa or single molecular markers will generally not be accepted.
