Item The first record of karyotypes in Leiurus abdullahbayrami and Compsobuthus matthiesseni (Scorpiones: Buthidae) from Turkey(Editura Universitati din Oradea, 2014) Stahlavsky F.; Koç H.; Yağmur E.A.The karyotypes of Leiurus abdullahbayrami Yağmur, Koç and Kunt, 2009 and Compsobuthus matthiesseni (Birula, 1905) from Turkey are presented for the first time. Both analyzed species have achiasmatic meiosis and the same number of holocentric chromosomes (2n=22) gradually decreasing in size. During the first meiotic division we observed tetravalent in one male of L. abdullahbayrami and octovalent in one male of C. matthiesseni. These types of multivalents may increase genetic variability and indicate reciprocal translocations within these species. © NwjZ, Oradea, Romania, 2014.Item Molecular cytogenetics of Androctonus scorpions: An oasis of calm in the turbulent karyotype evolution of the diverse family Buthidae(Blackwell Publishing Ltd, 2015) Sadílek D.; Nguyen P.; Koç H.L.; Kovařík F.; Yağmur E.A.; Stahlavsky F.Recent cytogenetic and genomic studies suggest that morphological and molecular evolution is decoupled in the basal arachnid order Scorpiones. Extraordinary karyotype variation has been observed particularly in the family Buthidae, which is unique among scorpions for its holokinetic chromosomes. We analyzed the karyotypes of four geographically distant species of the genus AndroctonusEhrenberg, 1828 (Androctonus australis, Androctonus bourdoni, Androctonus crassicauda, Androctonus maelfaiti) (Scorpiones: Buthidae) using both classic and molecular cytogenetic methods. The mitotic complement of all species consisted of 2n=24 elements. Fluorescence in situ hybridization with a fragment of the 18S ribosomal RNA gene, a cytogenetic marker well known for its mobility, identified a single interstitial rDNA locus on the largest chromosome pair in all species examined. Our findings thus support the evolutionary stasis of the Androctonus karyotype, which is discussed with respect to current hypotheses on chromosome evolution both within and beyond the family Buthidae. Differences in karyotype dynamics between Androctonus spp. and the other buthids can help us better understand the driving forces behind their chromosome evolution and speciation. © 2015 The Linnean Society of London.Item Determination of the median lethal dose and electrophoretic pattern of Hottentotta saulcyi (Scorpiones, Buthidae) scorpion venom(Tehran University of Medical Sciences, 2015) Yağmur E.A.; Özkan Ö.; Karaer K.Z.Background: In this study, we investigated the lethal potency, electrophoretic protein pattern and in vivo effects of Hottentotta saulcyi scorpion venom in mice. Methods: Scorpions were collected at night, by using a UV lamp from Mardin Province, Turkey. Venom was obtained from mature H. saulcyi scorpions by electrical stimulation of the telson. The lethality of the venom was determined by i.v. injections using Swiss mice. In vivo effects of the venom were assessed by using the intraperitoneal route (ip) injections into mice (20±1g) and monitored for 24 h. The protein profiles of the scorpion venom were analyzed by NuPAGE® Novex® 4-12 % gradient Bis-Tris gel followed by Coomassie blue staining. Results: The lethal assay of the venom was 0.73 mg/kg in mice. We determined the electrophoretic protein pattern of this scorpion venom to be 4, 6, 9, 31, 35, 40, 46 and 69 kDa by SDS-PAGE. Analysis of electrophoresis indicated that H. saulcyi scorpion intoxicated mice exhibited autonomic nervous system symptoms (tachypnea, restlessness, hyperexcitability, convulsions, salivation, lacrimation, weakness). Conclusions: Hottentotta saulcyi scorpion venom includes short-chain neurotoxins and long-chain neurotoxins according to the electrophoretic protein patterns. The stings of H. saulcyi scorpion must be considered of risk for humans in the southeastern region, Turkey.Item A new species of Zachaeus C.L.

Der klinische verlauf eines giftigen stiches des skorpions Leiurus abdullahbayrami in der Türkei](Arachnologische Gesellschaft e.V., 2016) Seiter M.; Koç H.; Ullrich A.; Yağmur E.A.Scorpion stings are very common in Turkey. Nevertheless, they are not well documented in the literature and were never reported for the recently described scorpion species Leiurus abdullahbayrami Yağmur, Koç & Kunt, 2009. Here, we report a case in which a 30-year-old male was stung by a L. abdullahbayrami scorpion in the field. He was directly brought to the emergency department of the local hospital. The symptomatic process was observed and documented. In this case, no antivenom was necessary; we hypothesize that the scorpion has used most of its venom in a previous incident (explained in further detail below) and was therefore not able to inject a normal dosage. © 2016, Arachnologische Gesellschaft e.V.

Neutralization capacity of monovalent Androctonus crassicauda antivenom (RSHA anti-Ac) was tested against the lethal effects of the venoms. Venom was obtained from mature scorpions by electrical stimulation of the telson. The lethality of the venom and potency of Horse RSHA anti-Ac were determined in Swiss mice. The protein profiles of the scorpion venoms were analysed by NuPAGE® 4–12% gradient Bis-Tris gel followed by Coomassie blue staining. Western blotting was performed to determine immunogenic compounds in the venom samples. The median lethal doses of M. e. eupeus, M.gibbosus scorpion and A.crassicauda venoms were determined to be 1.92 mg/kg by i.v. injection route, 0.67 mg/kg and 0.24 mg/kg by s.c. injection route, respectively. A.crassicauda (Olivier, 1807) venom was used as control. One millilitre of the RSHA anti-Ac neutralises 23 LD50 of M. e. eupeus, 32 LD50 of M.gibbosus and 42 LD50 of A. crassicauda venom in mice. Analysis of electrophoresis indicates that three scorpion venoms posses low molecular weight proteins. Immunoblotting indicated that RSHA anti-Ac strongly reacted with both the specific venom and Mesobuthus species venoms which have antigenic similarity. The result of our study showed that M.e. eupeus and M.gibbosus could be medically important scorpions for humans, particullary children. The RSHA anti-Ac can be used in the treatment of envenomation by M. e.eupeus and M.gibbosus scorpion stings. © 2017 by School of Pharmacy.Item Genetic diversity within Scorpio maurus (Scorpiones: Scorpionidae) from Turkey(Editura Universitati din Oradea, 2017) Koç H.; Sipahi H.; Yağmur E.A.In this study, DNA sequence diversity of the mitochondrial (mt) cytochrome oxidase 1 (CO1) gene was investigated in Scorpio maurus specimens from across southeastern Turkey. Nucleotide sequences included 508 conserved sites and 126 variable sites, and the mean nucleotide variation within species was 7.9%. Intraspecific pairwise divergences ranged from 0.5% to 10.7%. Phylogenetic analysis indicated high divergence among specimens. This study is the first mtDNA sequence analysis for Turkish scorpions. © NwjZ, Oradea, Romania, 2017.Item Phylogenetic relationships among the Leiurus abdullahbayrami (Scorpiones: Buthidae) populations in Turkey inferred from mitochondrial DNA sequence data(Universitatea din Oradea, 2018) Ayhan H.; Atay E.; Çarhan A.; Yağmur E.A.; Özkan Ö.; Çelebi B.Mitochondrial DNA (mtDNA) has been widely employed in phylogenetic studies. Leiurus abdullahbayrami was recognised has representing a different Leiurus scorpion species in 2009, with several morphological characters that differentiate it from Leiurus quinquestriatus, the genus type species. In this study, Leiurus abdullahbayrami samples collected from the provinces of Hatay, Kilis, Gaziantep, Şanliurfa, Adiyaman, and Mardin in Turkey were used as study material. The genetic identification of the L. abdullahbayrami (Scorpiones: Buthidae) was carried out by using the 16S mitochondrial gene, subunit of mtDNA. According to the results of this study, the little genetic difference between the groups was confirmed and the taxonomic validity of Leiurus abdullahbayrami was confirmed with molecular data. The 16S rRNA sequence data showed that the genus Leiurus seems to be represented in Turkey by a single species, L. abdullahbayrami. Nucleotide variations found in the current work constitute the first descriptive report for L. abdullahbayrami. ©Biharean Biologist, Oradea, Romania, 2018Item The scorpion fauna of West Azerbaijan Province in Iran (Arachnida: Scorpiones)(Universitatea din Oradea, 2018) Gharakhloo M.M.; Heydarabad S.A.; Yağmur E.A.In this study, investigation on the scorpion fauna related to borderline cities of West Azerbaijan Province (Poldasht, Piranshahr, Oshnaviyeh, Sardasht, Chaldoran, Salmas, Urmia and Khoy) was carried out.

All rights reserved.Item Kut gen. nov., a new troglomorphic spider genus from Turkey (Araneae, Dysderidae)(Pensoft Publishers, 2019) Kunt K.B.; Elverici M.; Yağmur E.A.; Özkütük R.S.A new genus of troglomorphic Dysderidae is described, based mainly on the morphology of copulatory organs. The new genus Kut gen. nov., with the type species Harpactocrates troglophilus Brignoli, 1978, also includes two recently discovered new species from the coastal Mediterranean Turkey: Kut izmiricus sp. nov. and K. dimensis sp. nov. All three species display troglomorphic traits, most distinct in K. dimensis sp. nov. Another genus-level trait is a characteristic simple type of bulb in males. Female copulatory organ shows similarity to the endemic Caucasian genus Cryptoparachtes Dunin, 1992 in paraspermatheca structure, whereas the male copulatory organ is unique among all known Dysderidae. © Kadir Boga-Kunt et al.Item First record of Androctonus bicolor Ehrenberg, 1828 (Arachnida: Scorpiones) with scorpion records Dhi Qar Province, Iraq(Universitatea din Oradea, 2019) Al-Khazali A.M.; Yağmur E.A.This study reports on the collection of scorpions from Dhi Qar province (South of Iraq). A total of 21 scorpion specimens were collected in 2017, and identified; all specimens belong to six species: Androctonus bicolor Ehrenberg, 1828, Buthacus macrocentrus (Ehrenberg, 1828), Compsobuthus matthiesseni (Birula, 1905), Mesobuthus phillipsi (Pocock, 1889), Orthochirus iraqus Kovařík, 2004, and Androctonus crassicauda (Olivier, 1807). All species except the latter are recorded for the first time from Dhi Qar province.

Some of the information about the body features of females which has not been known to date is given and pictures of female copulatory organ is also presented. H. christodeltshevi is in the rubicunda (D) group because of the structural features of the body and reproductive organs and its female copulatory organ is unique because of the spherical structure in the tip of the anterior spermatheca and sclerotized ring just under it. Additionally, it is debated that the species saved recently in Gaziantep, Turkey and recorded as Stalagtia hercegovinensis is actually H. christodeltshevi. © 2019, ABADER (Adıyaman Bilimsel Arastırmalar Dernegi).

Thus, the densities and seasonal activities of the species obtained were evaluated. At the end of the study, a total of 7.274 specimens were identified based on seven species, which are Astenus melanurus (Küster, 1853), A. procerus (Gravenhorst, 1806), Luzea graeca (Kraatz, 1857), Medon dilutus pythonissa (Saulcy, 1865), Paederus fuscipes Curtis, 1826, Scopaeus bicolor Baudi Di Selve, 1848 and S. debilis Hochhuth, 1851. It seems all recorded species are predators. The most abundant species are S. debilis with 7.006 specimens and P. fuscipes with 204 specimens. The identified species were found to be intense and active especially from mid-May to the end of July in general. According to the observations during field studies, it was found that P. fuscipes species was a predator of Aphis illinoisensis Shimer, 1866 and A. gossypii Glover, 1877 (Homoptera, Aphididae) species. This species is most active at the beginning and the end of dry summer. © 2021 Gazi Entomological Research Society.

Iuridae taxa are mainly found in Turkey and Greece, whereas a single species is found in northern Iraq. Several taxonomic revisions have been conducted on this family that initially comprised two genera. The latest taxonomic review, based on morphological and anatomical features, raised the number of Iuridae genera to four, and the number of species to 14. Sequence data from three molecular markers (COX1, 16S rDNA, ITS1) originating from numerous Iuridae taxa were analyzed within a phylogenetic framework. Divergence time-estimate analyses, species delimitation approaches and estimation of ancestral areas were implemented in order to: (1) reconstruct the phylogenetic relationships of the Iuridae taxa, (2) evaluate the morphological classifications, and (3) obtain insights into the biogeographic history of the family in the East Mediterranean. The multi-locus phylogeny clearly confirms an ancient division into two clades, Calchinae and Iurinae. Ancient patterns of isolation and dispersal are revealed. Both subfamilies are largely confined to the Anatolian peninsula and its few coastal islands; only the most derived genus Iurus has dispersed westward to Crete and Peloponnese. Based on our findings, three new genera of Iurinae (Metaiurus, Anatoliurus, and Letoiurus) are established. The genus Neocalchas emerges as one of the most ancient scorpion clades, with divergence time about 27 mya. © 2022 Elsevier Inc.Item An Anomaly of Pecten in Mesobuthus turcicus Kovařík et al., 2022 (Scorpiones: Buthidae); [Mesobuthus turcicus Kovařík et al., 2022'ta bir pektin anomalisi (Scorpiones: Buthidae)](ABADER (Adıyaman Bilimsel Arastırmalar Dernegi), 2022) Yağmur E.A.; Sipahioğlu Ö.; Yilmaz Ö.; Kiliç M.S.An anomaly was recorded in the pecten shape of the scorpion species Mesobuthus turcicus Kovařík et al., 2022 that was recently described from Türkiye. In this case, it is observed that marginal and median lamellae and fulcrae are fused in the right pecten. For this reason, the pecten is bent counter clockwise. Different from other pectinal anomalies, the size of teeth is developed normally but teeth number is fewer. This teratological anomaly on pecten is described and illustrated. This is the first report of pecten anomaly based on marginal and median lamellae. © 2022, ABADER (Adıyaman Bilimsel Arastırmalar Dernegi). All rights reserved.Item HOTTENTOTTA POOYANI SP. NOV.
