Water mites of the genus Sperchon Kramer (Acari: Hydrachnidia: Sperchontidae) from Turkey, with description of two new species Author Esen, Yunus Author Pešić, Vladimir Author Erman, Orhan text Zootaxa 2010 2514 35 46 journal article 10.5281/zenodo.196102 815c8797-25b5-4277-b5bf-adb498c67aab 1175-5326 196102 Sperchon ( Sperchon ) glandulosus Koenike, 1886 Sperchon fundamentalis Bader & Sepasgozarian, 1980 n. syn. Material examined. NHMB , Sperchon fundamentalis NHMB 3, Iran 78/65 1718. Records from the study area: Konya Province—“ Sperchon fundamentalis “ Boyaci & Özkan (1994) , Rize Province—Pešić et al . (2007). Remarks. In the orginal description, Bader & Sepasgozarian (1980b) compared Sperchon fundamentalis with the taxonomically distant species S. cornutus K. Viets, 1935, S. cornutoides Lundblad, 1941, S. hirsutas Cook, 1967, S. ootacamundis Cook, 1967 and S. tridentatus Sokolow, 1940 but were not aware of the close similarity to S. glandulosus . In fact, neither figures nor measurements in the orginal description reveal any significant difference to S. glandulosus . Furthermore, re-examination of one specimen from the type series of Sperchon fundamentalis as well as much material from a different part of Iran attributed by Pešić et al. (2004) to the latter species did not produce any other morphological differences to S. glandulosus . Furthermore, the gnathosoma of all examined specimens has in its distal part a more or less elevated ventral keel and a more elongate and pointed rostrum, characters typical for S. glandulosus ( Lundblad, 1956 ) . Thus, S. fundamentalis should be considered a junior synonym of S. glandulosus . Distribution: Western Palaearctic.
