    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.

    Two new species of the genus Scorpio L., 1758 from Southеastеrn Turkey (Scorpiones: Scorpionidae)
    Yagmur, EA; Hussen, FS; Karakurt, S; Kurt, R; Sipahioglu, Ö; Kartal, I
    Two new species, Scorpio karakurti sp.n. and S. sirnakensissp.n. are described and illustrated from the South & iecy;ast & iecy;rn region of Turkey. S. karakurti sp.n. is detected from Batman and Diyarbak & imath;r provinces and can be distinguished from all species of the genus Scorpio by its higher pectinal teeth numbers, especially in males (10-11 in females and 11-15 in males)S. sirnakensis sp.n is detected from & Scedil;& imath;rnak province and can be distinguished by elongated chela and telson shape and genital operculum shape of females. The new species are compared with the known species of the genus Scorpio Linnaeus, 1758 in the Middle East.
