Diversity of leaf katydids (Orthoptera: Tettigoniidae: Phaneropterinae) of Dzanga-Ndoki National Park, Central African Republic, with selected records from other African countries.

Forty-four species of Phaneropterinae are recorded from Dzanga-NdokiNational Park in the Central African Republic. Eight species collected withinthe park are described as new to science: Phlaurocentrum morettoi n. sp., P.paratuberosum n. sp., P. elegans n. sp., Myllocentrum raggei n. sp., Poreuomenasanghensis n. sp., Cestromoecha longicerca n. sp., C. magnicerca n. sp., andGoetia purpurea n. sp. An additional new species from Guinea is describedfrom specimens preserved in the Museo Nacional de Ciencias Naturales ofMadrid, Poreuomena huxleyi n. sp. Eurycorypha stylata Stål, 1873 is recorded forthe first time from Burkina Faso and Brycoptera lobata Ragge, 1981 from IvoryCoast. The following synonyms are established: Enochletica affinis Bolívar,1906 is synonymized with Enochletica ostentatrix Karsch, 1896, Poreuomenagladiator Bolívar, 1906 is synonymized with Poreuomena forcipata Sjöstedt,1902, and Azamia doriae (Griffini, 1906) is synonymized with Azamia biplagiataBolívar, 1906. In addition, morphological characters of previously unknownfemales of Phaneroptera maculosa Ragge, 1956 and Eurycorypha canaliculataKarsch, 1890, and males of Myllocentrum stigmosum (Karsch, 1896) andCestromoecha crassipes (Karsch, 1890) are described. The presence of titillatorsin four African genera (Gelotopoia, Brycoptera, Phlaurocentrum and Azamia)is recorded for the first time. In the genus Zeuneria, a sub-equally bilobed,dorsally curved, dorso-lateral abdominal appendage is described for thefirst time. This new structure apparently delimits an abdominal gland ofunknown function on the second tergite.
