    (Magnolia Press, 2021) Taylan, Mehmet Sait; Şirin, Deniz; Sevgili, Hasan; Yeşilyurt, Fatih
    To date several studies have been carried out on Orthoptera fauna throughout Anatolia; however, there is no comprehensive study on the Orthoptera fauna of Hakkari Province. This study is a preliminary comprehensive research that deals with the less known Orthoptera (Insecta) fauna of Hakkari Province. In this respect, the records and possible localities were examined between the years 2018-2020 (except Kurdia uvarovi) for the Hakkari Province. Specimens were collected with the help of an insect sweep net or by hand. As a result of the field studies and literature research, it has been determined that the Orthoptera fauna in the province is represented by 51 genera and 69 species/subspecies belonging to 19 subfamilies in 8 families. In the study, 24 new records were noted for Hakkari Orthoptera fauna and Isophya iraca Maran, 1977 (syn. n), which is established as a new synonym of I. hakkarica Karabag, 1962. According to our preliminary research, the Orthoptera fauna of Hakkari includes 32 Ensiferan and 37 Caeliferan members. In the Ensifera suborder (long antennae katydids, crickets and allies), 25 species belonging to the Tettigoniidae, 5 species belonging to Gryllidae, and one species for the each of Myrmecophilidae and Gryllotalpidae families have been identified. Caelifera suborder includes 26 species belonging to the Acrididae, 9 species belonging to the Pamphagidae, and one species for each of the Pyrgomorphidae and Tetrigidae families. During the field studies, it was observed that the Uvarovistia satunini (Uvarov, 1916), Uvarovistia zebra (Uvarov, 1916) and, Bradyporus (Callimenus) latipes (Stål, 1875) species have high population densities. They "swarm" and damage the agricultural areas especially in the Durankaya, Bayköy, Bagisli, and Kirikdag regions. For this reason, it is suggested that the populations of these species should be routinely monitored in agricultural areas. © 2021 Magnolia Press. All rights reserved.

    A review of the Anatolian Gomphocerus Thunberg, 1815 (Orthoptera: Acrididae: Gomphocerinae) via morphological and bioacoustics characters: data suggesting a new species, a new subgenus and three new statuses
    (Magnolia Press, 2023) Mol, Abbas; Sirin, Deniz; Taylan, Mehmet Sait; Sevgili, Hasan
    Gomphocerus Thunberg, 1815 (Orthoptera, Acrididae, Gomphocerinae) is an interesting genus with clavate antennae, differing from the other genera by the pyriform (pear-shaped) anterior tibiae in the male and being represented by 17 taxa species-subspecies in the Palaearctic region. Anatolian species of this genus have not been adequately studied, and almost all of them are cold tolerance species and live in high mountain meadows. The previous studies indicate that the taxa belonging to Gomphocerus have some taxonomic problems in both Turkey and the Palaearctic region. For this reason, the genus needs taxonomic revision due to its biogeographical, biodiversity, taxonomical and faunistic issues for which morphological and bioacoustics characteristics are to be used. This study was carried out between the years 2015 and 2021 at different altitudes and habitats of the mountains, where Gomphocerus specimens were collected from various localities in Anatolia. Since the species belonging to the genus have distinct morphological differences, the genus is divided into two subgenera: the nominate subgenus and a new subgenus Bolivarianus Mol, subgen. n. In addition, a new species of the nominate subgenus Gomphocerus (Gomphocerus) eyluldenizi Mol, sp.n. is described from Erzurum province (Eastern Anatolia) and when both morphology and bioacoustics characteristics are evaluated, three subspecies of the genus distributed in Anatolia are designated at species level: Gomphocerus (Gomphocerus) turcicus Mistshenko, 1951 stat. n. et sp. rev., Gomphocerus (Bolivarianus) acutus Karabag, 1957 stat. n., and Gomphocerus (Bolivarianus) hemipterus Karabag, 1953 stat. n. Furthermore, a key to the subgenus and species level for Anatolian members of Gomphocerus is provided with original figures, a distributional map and suggestions for conservation status according to IUCN categories are presented.

    Bioacoustics characterization of some anatolian endemic and sub-endemic Katydids (Orthoptera; Tettigoniidae; Bradyporinae, Phaneropterinae and Tettigoniinae)
    (Magnolia Press, 2019) Taylan, Mehmet Sait; Mol, Abbas; Sevgili, Hasan; Şirin, Deniz
    Seventeen endemic and time sub-endemic species belonging to three subfamilies of Tettigoniidae (Orthoptera: Bradyporinae, Phaneropterinae and Tettigoniinae) were sampled during field trips throughout different regions of Anatolia between 2015 and 2018 (except one taxon). Acoustic parameters of these 20 bush-cricket species affiliated to 12 genera (Apholidoptera, Bradyporus, Decticus, Eupholidoptera, Parapholidoptera, Pezodrymadusa, Pholidoptera, Polysarcus, Psorodonotus, Squamiana, Uvarovistia and Yalvaciana) have been described for the first time in this study. Bioacoustical analysis shows that male calling songs are species-specific for the genera Bradyporus, Parapholidoptera, Pholidoptera, Apholidoptera, Uvarovistia and Psorodonotus. However, there are no distinct differences among species of the genus Pezodrymadusa. Moreover, our additional data on genus Eupholidoptera indicate that there are some different song patterns within the genus. The song description of Uvarovistia zebra presented here is the second bioacoustics data on this genus. The acoustical analyses data support the morpho-species hypothesis of Psorodonotus suphani Taylan & Sirin, 2014, which is known from Suphan Mountain (Bitlis province, Eastern part of Turkey) and reject Kaya & ciplak (2017), which recommended it as synonym to P. caucasicus (Fischer von Waldheim, 1846) (commonly known as a Black Sea Region species).

    Bioacoustics review of Anatolian species of the predatory bush-cricket genus Saga (Orthoptera: Tettigoniidae: Saginae) with the description of a new species
    (Magnolia Press, 2019) Şirin, Deniz; Taylan, Mehmet Sait; Sevgili, Hasan; Mol, Abbas
    The genus Saga is a genus of generally large predatory bush-cricket species. It includes 13 taxa in the Palaearctic region. In this research, eight species belonging to Saga (Tettigoniidae, Saginae) were sampled during field studies in different regions of Anatolia of Turkey between 2010 and 2018 (except one specimen). The bioacoustic parameters of these species recorded during the field or in laboratory conditions and the male calling song descriptions, as well as the oscillographic illustrations and distribution maps are given. A new population of Saga found from the South-Eastern Taurus (Hakkari province), which is affiliated to a new species and shows similarity to S. ephippigera, along with the morphological and bioacoustical descriptions of Saga hakkarica sp. n. Sirin & Taylan from Turkey, are also given. The relationships between the new species and the closest taxa are discussed using morphological and bioacoustical characters. The structural investigations of the male calling songs reveal three different bioacoustic groups affiliated to eight Anatolian Saga species; as (i) Ephippigera group (S. syriaca + (S. ephippigera + Saga hakkarica), (ii) Natoliae group (S. natoliae + (S. beieri + (S. longicaudata + S. puella) and (iii) S. cappadocica.

    Review of the Poecilimon (Poecilimon) zonatus species group and description of new species from Turkey with data on bioacoustics and morphology (Orthoptera: Phaneropterinae)
    (Magnolia Press, 2018) Sevgili, Hasan; Şirin, Deniz; Heller, Klaus Gerhard; Lemonnier Darcemont, Michele
    The aim of this study is to conduct a detailed taxonomic revision of the Poecilimon (Poecilimon) zonatus species-group (Orthoptera: Phaneropterinae) using both morphology and bioacoustics. Two new species (Poecilimon (Poecilimon) salmani, P. (P) azizsancar) and one new subspecies (P. (P) zonatus datca) are described. Based on the data, we conclude that the species complex can be separated into two subgroups (P. tauricola and P. zonatus). Within the P. zonatus subgroup, song structures indicate P. variicercis as basal branch since producing two syllable types is possibly a derived character. From both, from bioacoustics and morphology, it is concluded that the relationships between species of the group are as follows: P. tauricola subgroup (P. tauricola + P. azizsancar) + P. zonatus subgroup (P. variicercis + (P. varicornis + (P. zonatus zonatus + P. zonatus datca)) + (P. salmani + P. vodnensis)))). Except for two species (P. vodnensis and P. varicornis), the other species of the group are all distributed in Anatolia. P. vodnensis is known only from Macedonia, whereas, P. varicornis has been recorded only from Syria and Lebanon. We assume that the group originated from an Anatolian ancestral stock and expanded its distribution to the Balkans through Taurus Way and Dardanelles. Other ancestral populations may have also spread in the north-south directions through the appropriate steppe corridors in the Anatolian Diagonal Mountains and in its vicinity.
