Solifuges can be distinguished from other arachnid orders by large chelicerae for body size, adhesive suctorial organ at the distal end of each pedipalp, and malleoli (racquet organs) located on the ventral surface of forth pair of walking legs among the arachnids. In this study, the cuticle surfaces of these structures were studied by scanning electron microscopy in males of Rhagodes caucasicus Birula, 1905 and Rhagodes eylandti (Walter, 1889). Different types of setae, sensilla and epicuticular protrusion were described and their possible functions were discussed.
