The diversity of cave crickets (Orthoptera, Rhaphidophoridae) remarkably differs between geographic regions in Anatolia. While only 4 species are distributed in northern Anatolia where Black Sea climate prevails, 14 species are found throughout southern and western Anatolia where the Mediterranean climate is dominant. However, no cave crickets were reported from the middle and eastern Anatolia where the continental climate is present. There is no data-based study on the distribution pattern of cave cricket species in Anatolia. This study aimed to reveal any possible relation between climatic conditions and distribution of cave crickets in three caves selected as representatives for three climate types present in Anatolia. Temperature and relative humidity in the ecological zones of the given caves and the surface were periodically measured by using data loggers. Our data show within cave variations in temperature and relative humidity among all three caves: (i) variations in temperature and relative humidity decreased from the entrance zone to the dark zone, (ii) over the winter period, temperature increased from the entrance zone to the dark zone, (iii) over the summer period, temperature decreased from the entrance zone to the dark zone, (iv) the most distinct temperature variation was measured in continental climate, and (v) the major similarity of climatic conditions between cave and climate type was observed in the Black Sea region which cave crickets species have widened distribution and limited speciation.

A new species and taxonomic notes on some Anatolian and Syrian species of cave crickets Dolichopoda (Orthoptera: Rhaphidophoridae): Following the trail of Martinez de la Escalera after 123 years
(Taylor & Francis Ltd, 2023) Taylan, Mehmet Sait; Şirin, Deniz; Paris, Mercedes
We examined cave crickets in southern Anatolian and northern Syrian in areas where Martinez de la Escalera collected at the end of the 19(th) century and compared our material with type material. We found a new species of the genus Dolichopoda Bolivar, 1880, D. rampinii Taylan & Sirin sp. n. from Anatolia (Hatay province). Additionally, some taxonomical notes and new figures of both sexes for D. pusilla Bolivar, 1899 and D. aranea Bolivar, 1899 are given according to syntype specimens. The new species, which is collected from Akbez cave (Turkey, Hatay province). Our data obtained from the type specimens indicates the validation of D. pusilla and D. aranea. Dolichopoda pusilla has to be removed from the Turkish list, as the collection locality is now located in Syria.

(Magnolia Press, 2014) Taylan, Mehmet Sait; Mol, Abbas; Şirin, Deniz
Descriptions of a new species of Tettigoniinae; Psorodonotus suphani sp. n. from Turkey were given. The relationships between the new species and closest taxa (morphologically and geographically) were evaluated by using morphological characters. Ultimately, some remarkable points of the distribution pattern of the species were presented.
A preliminary research and notes on Orthoptera (Insecta) Fauna of Hakkari Province
(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.

Contribution to the Knowledge of Ensifera (Insecta: Orthoptera) Fauna of Turkey
(Gazi Entomological Research Soc, 2016) Mol, Abbas; Taylan, Mehmet Sait; Demir, Eyup; Şirin, Deniz
In this study which contributes to the distribution of species of Ensifera (Insecta: Orthoptera), which are known as bush-crickets, in Turkey, specimens of Tettigoniidae, Gryllidae and Gryllotalpidae (Orthoptera) collected from Turkey and preserved in Aksaray University and Namik Kemal University have been examined. As a result, a total of 117 species-subspecies belonging to 37 genera of the family Tettigoniidae, 6 species belonging to five genera of the family Gryllidae and one species belonging to one genus of the family Gryllotalpidae have been determined from the examined material. Of these species, 67 species are endemic to Turkey, and 12 are harmful to agricultural crops.
Contribution to the knowledge of two endemic species of Anatolian Gomphocerinae Fieber, 1853 (Orthoptera: Acrididae)
(Magnolia Press, 2015) Mol, Abbas; Taylan, Mehmet Sait; Şirin, Deniz
This study focuses on two endemic Anatolian Gomphocerinae Fieber, 1853 species, which are evaluated in terms of nomenclature and taxonomy using biogeographical, morphological, and acoustical data. The original description of Eremippus zeybekoglui is supplemented by the data on new specimens collected from type locality, and the female of this species is described for the first time in this study. Based on the new specimens of Stenobothrus weidneri (Demirsoy, 1977) comb. nov., which were collected at the type locality, the species is transferred from Eremippus Uvarov, 1926 to Stenobothrus Fischer, 1853. Additionally, male calling songs of both species are described for the first time in this study. Also, the biogeography of these species is presented and discussed.
Description of a New Species of the Genus Troglophilus Krauss, 1879 (Orthoptera: Rhaphidophoridae) from Northern Anatolia, Turkey
(Gazi Entomological Research Soc, 2015) Taylan, Mehmet Sait; Mol, Abbas; Şirin, Deniz
In this paper a new species of cave crickets Troglophilus (Orthoptera, Rhaphidophoridae) from northern Anatolia is described as Troglophilus aspegi Taylan and Sirin sp. nov.. Considering the other already recognised nine species in Anatolia, there are now total 10 species of Troglophilus that currently inhabit the caves and epigean habitats of Turkey. The new species is restricted to National Park of Kure Daglari in Bartin province and known only in one locality (Sipahiler cave). Troglophilus aspegi is morphologically distinguishable from the other nine Troglophilus species present in Turkey due to their small size, male tenth tergite, ovipositor shape, reddish-light brown body color. New species differs from the morphologically closest T tatyanae for body color, tenth tergite and epiphallus shape in male, subgenital plate shape in both sexes, length of the appendages and spinulation of the legs. On the other hand, these new data show that geographical distribution of Troglophilus is not only restricted with north eastern Anatolia but also in caves from north western section of Blacksea Region of Turkey.
First song descriptions of some Anatolian species of Tettigoniidae Krauss, 1902 (Orthoptera, Ensifera)
(Pensoft Publishers, 2014) Şirin, Deniz; Taylan, Mehmet Sait; Mol, Abbas
Fourteen endemic and two sub-endemic species belonging to three subfamilies of Tettigoniidae (Tettigoniinae, Bradyporinae and Saginae) were sampled during field trips throughout the different ranges of Anatolia between the years of 2004 and 2013. Acoustic parameters of these 16 species affiliated to 8 genera (Anterastes, Apholidoptera, Gampsocleis, Parapholidoptera, Pezodrymadusa, Psorodonotus, Bradyporus and Saga) have been described for the first time in this study. Acoustical analysis showed that song characters are species-specific in the genera Saga and Psorodonotus. On the other hand, we could not find big differences among species of the genus Pezodrymadusa and Parapholidoptera castaneoviridis species-group.
Molecular genetics and phylogeny of Ephippigera species group of genus Saga Charpentier, 1825 (Orthoptera: Ensifera: Saginae) in Anatolia
(Magnolia Press, 2021) Binici, B.; Şirin, Duygu Yaşar; Taylan, Mehmet Sait
The genus Saga, one of the largest predatory bush crickets and insects in the Palearctic region, is represented by nine species in Anatolia. According to the morphological and bioacoustics evaluations of the Ephippigera species group belonging to the Saga genus, it consists of three species: S. ephippigera, S. syriaca, and S. hakkarica. To the present, however, there is no molecular genetic research on this species group. In our study, by using the 16S rDNA gene sequences, the molecular phylogeny of this species group is revealed and the morphological species hypotheses has been tested. In the study, specimens belonging to S. ephippigera, S. syriaca, and S. hakkarica were collected between the years of 2018 and 2020 with sweep netting; the DNA isolation, polymerase chain reactions, purifications and double-stranded sequencing were performed to obtain 16S rDNA gene sequences. Sequences were evaluated phylogenetically by performing alignment, phylogenetic analysis (Maximum Likelihood and Bayesian Inference), and dating of cladogenetic events, respectively. The monophyletic and species hypotheses of all three species have been supported by molecular data. It has been determined that the S. ephippigera species is the origin lineages of the Ephippigera species group which diverged approximately 0.4 million years ago; it has been also revealed that the climatic changes in the glacial and inter-glacial periods in the Middle Pleistocene period affected greatly the evolution of the species group.

Phylogenetic and phylogeographic analysis of Myrmeleotettix maculatus (Orthoptera: Acrididae: Gomphocerinae) species group in Anatolia
(Magnolia Press, 2021) Şirin, Deniz; Taylan, Mehmet Sait; Bircan, Rifat; Akyıldız, Gürkan; Can, Levent
Six Anatolian and one European populations of the Myrmeleotettix maculatus species group, which contains M. maculatus and M. ethicus species, have been studied by using molecular genetics methods with mitochondrial COI gene. Myrmeleotettix ethicus is an Anatolian endemic species with local distribution whereas M. maculatus is distributed in western Palearctic. The phylogenetic analysis (ML and BI analyses) of the M. maculatus species group in Anatolia reveals that it consistently recovered two well-supported main clades and four different lineages. Molecular time estimates suggest that the diversification of the M. maculatus species group took place between the Late Tortonian (around 8-9 My) and the Middle of Pliocene-Pleistocene (around 4.3 My-present) periods and the current distribution of the genetic diversity has been affected by the uplifting of the Central Anatolian plateau, the termination of the Messinian salinity crisis, and the Quaternary climatic changes.

Speciation of the genus Dolichopoda in Anatolia with reference to the role of ancient central lake system
(Brill Academic Publishers, 2016) Taylan, Mehmet Sait; Şirin, Deniz
The aim of this study was to determine of the evolutionary relationships of the Turkish Dolichopoda species, and to define and clarify the systematics of the group in Anatolia. For this purpose, we have examined some 27 populations of the genus Dolichopoda from Anatolia and adjacent regions (Caucasia and the Greek islands). A total of 532 bp of the mitochondrial 16S rDNA gene was sequenced in order to clarify the phylogenetic relationships of the genus. Five main clades can be distinguished and well-supported by phylogenetic analyses. In these clades, the results obtained from Samos Island and Anatolia are remarkable. In contrast to some previous studies, our results point to an Aegean origin of the Anatolian Dolichopoda species. According to the mitochondrial 16S rDNA divergence data, the current distribution of the genetic diversity was affected by ancient central lake system, habitat types, Messinian period and Plio-Pleistocene characterized by alternating dry/cold and warm/humid stages.
The distribution of Gomphocerinae taxa in the Black Sea region of Turkey: the role of vegetations and elevations
(Gazi Entomological Research Society, 2019) Mol, Abbas; Taylan, Mehmet Sait; Zeybekoğlu, Ü.; Şirin, Duygu Yaşar
In the conducting the present study, the Gomphocerinae specimens were collected from June to September between 2003 and 2017 according to factors such as the Black Sea Region’s topography, its vegetation and altitudes. A total of 207 different localities (including 70 main localities) from 25 provinces in region (7 of them from neighbour to region provinces) were visited. Approximately 5991 adult sample belonging to Gomphocerinae subfamily were collected from the Black Sea region. The collected samples comprised 53 Gomphocerinae taxa, belonging to 17 genera. The total number of Gomphocerinae taxa in the study area reached to 59 with six species from the literature. According to data from this study and other literature, the Black sea region ranks first among the geographical regions of Turkey with regard to the presence of the Gomphocerinae genera and its species number. It has been determined that some 17 species in area belong to Europe (Boreal) sub-region in Palaearctic. The data reveal that the Gomphocerinae taxa prefers mostly altitudes ranging between 600 and 2250 meters in Castanetum zone, Broad-leaf deciduous forest zone, and subalpine meadows in this elevational range. According to all data from this study, the Gomphocerinae taxa prefer the Black Sea Region as refugia. © 2019 Gazi Entomological Research Society. All rights reserved.
