Description: The descriptions and figures provided by Láska (1965) and Biesiadka (1975) adequately define S. procera . Discussion: Laska (1965) based his description of S. procera on three females ( syntypes ) collected from two streams, the Velká Bielá Voda in Slovakia (Ƥ, 18.7.58 ) and the Miloňovsky in Moravia (2Ƥ, 13.8.64 ). Comparison of the two female specimens from Moravia with the 3 and Ƥ from Montenegro and the original descriptions by Laska (1965) for S. verrucosa procera and Biesiadka (1975) for S. phreaticus indicated their conspecificity. Thus S. phreaticus Biesiadka should be considered a junior synonym of S. procera Láska.
