Preliminary taxonomic study of the Grylloidea of Spain (Insecta, Orthoptera)

Abstract

In the present paper a taxonomic and faunistic study of the superfamily of Grylloidea of Spain including the Balearic and Canary Islands is carried on. Sixty species and subspecies are reported for the study area, six of them new to science: Petaloptila (P.) fermini, P. (P.) isabelae, P. (Zapetaloptila) venosa, P. (Z.) barrancoi, Paramogoplistes dentatus sp. n. and Grylloderes orlovskajae adventicius subsp. n.; likewise are erected two new subgenera Italoptila and Zapetaloptila. One correct synonymy of the genus Grylloderes Bolívar, 1894 (=Platygryllus Chopard, 1961, syn. dist.), seven specific synonymies are established: Gryllomorpha (G.) dalmatina (Ocskay, 1832) (=Gryllomorpha dalmatina strumae Andreeva, 1982, syn. n.), Petaloptila (P.) aliena (Brunner-Wattenwyl, 1882) (=Discoptila eitschbergeri Harz, 1976, syn. n.), Acheta hispanicus Rambur, 1839 (=Gryllus erythrospilus Walker, 1869, syn. n., Gryllus hispanicus var. fusculus Bolívar, 1927, syn. n.), Eumodicogryllus bordigalensis (Latreille, 1802) (=Gryllodes ferdinandi Bolívar, 1899, syn. n., Gryllus chinensis var. intermedia Bolívar, 1927, syn. n.), Eugryllodes pipiens (Dufour, 1820) (=Gryllodes pipiens var. provincialis Azam, 1901, syn. n.) and besides five new status and one new combination. Three species [Eumodicogryllus theryi (Chopard, 1943), Sciobia natalia Gorochov, 1985 and Oecanthus dulcisonans Gorochov, 1993] are recorded for the first time for the Iberian Peninsula, being the former two also new for Europe, one (Svercus p. palmetorum Krauss, 1902) for Peninsular Spain, three [Natula averni (Costa, 1855), comb. n., Acanthogryllus acus Gorochov, 1988, under this name, and Pseudomogoplistes vicentae Gorochov, 1996], for the Canary Islands, being latter recorded also for the first time for Algeria and Modicogryllus (M.) algirius (Saussure, 1877) is also recorded for the first time for France. On the other hand, we recognise Eugryllodes panteli (Cazurro, 1888) as a good species. An identification key with figures for the species of the genus Petaloptila is presented. The male genitalia of several species is also studied for the first time. The type series of Gryllodes macropterus Fuente, 1894 and Gryllotalpa septemdecimchromosomica Ortiz, 1958 and two paratypes of Gryllomorpha adspersa merobricensis Fernandes, 1959, stat. n. are localized. Lectotypes and paralectotypes of 17 taxons are designated. The distribution of all species is revised.
