Phalangopsidae crickets from Tropical Africa (Orthoptera, Grylloidea), with descriptions of new taxa and an identification key for African genera Author Desutter-Grandcolas, Laure text Zootaxa 2015 3948 3 451 496 journal article 10.11646/zootaxa.3948.3.5 48fd46c1-a333-45ef-85fd-bb89451998da 1175-5326 241857 809AC895-779E-419D-8EBE-071F0ACCD72E Key to African genera of Phalangopsidae Remarks. Larandeicus has three apical spurs on TI, set in a close triangle. It is consequently clear that this taxon does not belong to the family Phalangopsidae sensu Desutter-Grandcolas et al. (submit.), defined after the clade E of Chintauan-Marquier et al. (2013 , 2015 ) phylogeny. It should be transferred to the temporary family Gryllidae , grouping the clades F and G of the above mentioned topology. Hirpinus (one species, Southern Africa) has been synonymized with Homoeogryllus by Saussure (1878) , and later reconsidered as a valid taxon in the catalogues of Kirby (1906) and Chopard (1968) . Both genera are actually very similar morphologically. As the type of Hirpinus afer Stål, 1855 could not be observed to confirm the status of the genus, both genera are considered in the key below. Zaora (one species, Southern Africa) has been positioned in the key according to the diagnosic characters given by Walker (1869) throughout his whole paper and according to the pictures of the type specimen of Zaora morbillosa Walker, 1869 made by S. Hugel (pers. comm.). The two other species described by Walker (op. cit.) have been transferred either to Amphiacusta Saussure, 1874 , or to Endacusta Brunner von Wattenwyl, 1873. Saussure (1878) transferred Zaora morbillosa to Gryllomorpha : according to its morphology, Zaora morbillosa actually looks close to this last genus. If confirmed, this relationship would enhanced the distribution of the Gryllomorphini to Southern Africa, while is is presently known from the Mediterranean region only. Gryllomorpha , Petaloptila and Hymenoptila are included in the key below, even if the last genus could not be used for molecular studies. 1.
