ZOOSYSTEMATICA ROSSICA, 18(1): 25-47 3 JULY 2009 A study of the genus Gryllomorpha Fieber, 1853 (Orthoptera: Gryllidae: Gryllomorphinae) A.V. GOROCHOV A.V. Gorochov, Zoological Institute, Russian Academy of Sciences, Universitetskaya nab. 1, St. Petersburg 199034, Russia; [email protected] Twenty six species and subspecies of the genus Gryllomorpha are considered. Twelve of them are included in the nominotypical subgenus: G. dalmatina dalmatina, G. d. schmidti stat. n.; G. longicauda longicauda nom. resurr.; G. l. adspersa stat. n.; G. brevicauda brevicauda, G. b. australis subsp. n.; G. b. borealis subsp. n.; G. occidentalis sp. n.; G. sovetica sp. n.; G. syriaca, G. rufescens, G. maghzeni. Fiftheen taxa are soundly or tentatively included in the subgenus Gryllomorphella: G. miramae miramae, G. m. guentheri, G. albanica, G. antalya sp. n., G. zonata zonata, G. z. ifni subsp. n., G. robusta sp. n., G. ?canariensis, G. atlas sp. n., G. segregata sp. n., G. mira, G. uclensis uclensis, G. u. algeriana, G. u. ?pygmaea, G. sternlichti. Type material for the majority of these species is briefly revised. Male copulatory structures for many species are described and illustrated for the first time. Neotype for G. dalmatina and Acheta aptera as well as a lectotype for Gryllomorpha zonata are designated.
