EXTERNAL MORPHOLOGICAL PROPERTIES OF ATEMNUS POLITUS (SIMON, 1878) (ARACHNIDA: PSEUDOSCORPIONES): A SCANNING ELECTRON 'MICROSCOPY STUDY

WOS:000592998800004Pseuodoscorpions (Pseudoscorpiones) have been little studied, although they are the third largest group in the Arachnida in number of species. Pseudoscorpions have features resembling those of true scorpions. Due to their small size (the largest pseudoscorpion being no larger than 1 cm) systematic studies have proven difficult. A high-performance microscope is necessary for detailed studies. In the present study. the pseudoscorpion Atemnuspolitus (Simon, 1878) collected in Osmaniye province. Turkey. was used to describe systematic and taxonomic characters, including chelicerae, pedipalps, walking legs. and cuticular structures on appendages using stereo light microscopy and scanning electron microscopy (SEM). The study revealed characteristic features of this species. This is the first SEM study of A. politus and provides an important contribution to understanding the morphology of pseudoscorpions and demonstrates the taxonomic value of SEM micrographs. Probable functions of some of the structures observed are discussed.Scientific Research Projects Coordination Unit of Kirikkale UniversityKirikkale University [BAP/2014-34]This study is a part of our project and has been supported by the Scientific Research Projects Coordination Unit of Kirikkale University (Project number: BAP/2014-34)

Comparative cheliceral morphology of the solifuge species Biton zederbaueri (Werner) and Gluviopsilla discolor (Kraepelin) through scanning electron microscopy (Arachnida: Solifugae: Daesiidae)

KOC, Halil/0000-0003-0429-2824;WOS: 000293426600014A detailed comparative morphology of the male chelicerae of Biton zederbaueri (Werner) and Gluviopsilla discolor (Kraepelin) is presented using stereo microscope and scanning electron microscopy (SEM). The morphology of the cheliceral teeth, setae, flagella and some other organs such as the stridulatory organ that are used for description and identification are described and illustrated. The flagella are membranous, but their shapes arc different in both species. The stridulatory organs are similar in both daesiids, being reniform and with seven ridges. On the chelicerae, numerous long-thin, short-thin and short-thick setae are characteristic for both species
