    Kunt, KB; Danisman, T; Yagmur, EA
    Two new Harpactea species, H. cosari sp. nov. (male female) andH. subterranea sp. nov. (male female), are described from the Manisa Province of T & uuml;rkiye. The two new species belong to the rubicunda species group based on the characteristics of the male and female copulatory organs. H. subterranea sp. nov. was sampled from the mesovoid shallow substratum using special traps. An apparent reduction of the eyes was observed as an adaptation to living underground. In addition to the new species, a new population of Harpactea cruriformis Bosmans, 2011, previously described from the Greek island of Chios, was discovered in & Idot;zmir province and reported as new to the spider fauna of T & uuml;rkiye. Also, the unknown female of H. cruriformis is described for the first time. The female copulatory organ of the species resembles that of Harpactea terveli Lazarov, 2009, as it is the male. Bulb and vulva images of Harpactea pugio Varol & Akp & imath;nar, 2016 and H. terveli, along with bulb images of H. kencei Kunt, Elverici, & Ouml;zk & uuml;t & uuml;k & Ya & gbreve;mur, 2011 and the holotype of H. cruriformis are included for comparison.

    Neutralization Capacity of Monovalant Antivenom Against Existing Lethal Scorpions in the Turkish Scorpiofauna
    Ozkan, O; Yagmur, EA
    In this study, Mesobuthus gibbosus and Mesobuthus eupeus eupeus venom samples were compared for lethality, in-vivo effects and proteins. 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 (R) 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.

    A comprehensive evaluation of the aculear sensory structures in scorpions (Arachnida: Scorpiones)
    Erdek, M; Yagmur, EA
    The scorpion telson is composed of a bulbous shaped base with two venom glands and an aculeus with two venom channels that open to the exterior. The cuticular surface of the aculeus is covered with aculear peg sensilla and pore holes. These sensillar pegs are located on the aculeus surface of the telson and function as contact chemoreceptors. Data on aculear peg sensilla are presented from both parvorders, four families, 15 genera and 15 species of extant scorpions. Although all aculear peg sensilla have a similar structure in all species and sexes in terms of their general morphology, their location and frequency on the surface of the aculeus cuticle varies. The shape of these sensilla is similar in all species, and the distribution density on the cuticle surface differs from species to species. The single slit sensilla were observed at various intervals and numbers in the aculeus-bulb connection area of the telson.

    Kut gen. nov., a new troglomorphic spider genus from Turkey (Araneae, Dysderidae)
    Kunt, KB; Elverici, M; Yagmur, EA; Özkütük, RS
    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.

    Scorpion-related cardiomyopathy and acute pulmonary edema in a child who is stung by Leiurus abdullahbayrami
    Dokur, M; Dogan, M; Yagmur, EA
    Venom of Leiurus abdullahbayrami (Scorpiones: Buthidae) is an extremely toxic one and it stimulates voltage-gated sodium and potassium channels. In case of a stung by this scorpion; excessive catecholamine release occur and it impairs left ventricle contractility and consequently a heart failure occurs (scorpion sting-related cardiomyopathy). In addition to this cardiac-induced acute pulmonary, edema may occur in severe cases too. An 11-year-old male child who was stung by a scorpion (species: Leiurus abdullahbayrami) consulted to the Emergency Room. Even after 7 h of scorpion envenomation he was confused and having hallucinations. Besides he was dyspneic, tachycardic, hypotensive and got worse in overall situation due to cardiogenic pulmonary edema. These clinical findings are concordant with the Level III scorpion envenomation (major systemic manifestations). Positive inotropic agents, diuretics and antiagregant agents used on supportive therapy in his treatment. After 2 weeks he get recovered and discharged from the pediatric intensive care unit. This research is conducted by thinking emergency physicians should learn that Leiurus abdullahbayrami envenomation can cause scorpion-related cardiomyopathy and acute pulmonary edema especially in children.

    External morphology of Hemiscorpius lepturus Peters, 1861 (Scorpiones: Hemiscorpiidae)
    Hussen, FS; Erdek, M; Yagmur, EA
    Hemiscorpius lepturus Peters, 1861 is redefined in both sexes. The detailed external mor-phologies of chelae, pectinal organs, chelicerae, tel-sons, and legs I-IV were surveyed with the scanning electron microscope (SEM) in both sexes of H. lep-turus for the first time. The constellation arrays, bat-like shaped peg sensilla, trichobothria, and the other sensillar and epicuticular structures were described, and their functional morphologies were interpreted considering the species' habitat and other climatic preferences. The constellation arrays, basiconic sen-silla, function as a chemoreceptor (hygro-reception or/and thermo-reception) by its location on the pedi-palp in the habitat. The shape of the peg sensilla is remarkably bat-like in both sexes and this shape has not been observed or recorded in any scorpion species, functioning as mechanoreception and contact chemo-reception. There are three slit sensilla as single slit, dual and triple slit sensilla on I-IV walking legs, being mechanoreceptors as proprioceptors detecting strain and substrate vibrations during movement. Isolated single slit sensillum was recorded on the chelicerae surface of a scorpion species for the first time.

    Determination of the Median Lethal Dose and Electrophoretic Pattern of Hottentotta saulcyi (Scorpiones, Buthidae) Scorpion Venom
    Yagmur, EA; Özkan, Ö; Karaer, KZ
    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 (R) Novex (R) 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.
