    THE TYPE LOCALITY OF RHAGODES CAUCASICUS BIRULA, 1905, AND THE FIRST RECORD OF THE SPECIES FROM IRAN WITH REDESCRIPTION OF THE SPECIES FROM TURKEY (SOLIFUGAE: RHAGODIDAE)
    Koç, H; Moradi, M; Erdek, M; Yagmur, EA; Gharahkloo, PM
    The type locality of Rhagodes caucasicus Birula, 1905 is corrected and identified as Tuzluca (Kul'p), Igdir Province, eastern Turkey instead of Armenia. A new record for the Iranian solpugid fauna is also reported: Rhagodes caucasicus Birula, 1905 from Zanjan Province, northwestern Iran. The redescription of new material of Rhagodes caucasicus from Turkey is included.

    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.

    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.
