139 ACTA ZOOLOGICA BULGARICA Acta zool. bulg., 67 (1), 2015: 139-142 Short communication Introduction The following species of the genus Axonopsis Piersig, 1893 are known for the fauna of Turkey: A. (Hexaxonopsis) romijniViets, 1923, A. (Hexaxonopsis) serrata Walter, 1928, A. (Paraxonopsis) vietsi Motaş & Tanasachi, 1947 and A. (Navinaxonopsis) persi- ca Pešić, 2004. Axonopsis romijni was reported as A. serrata for Malatya Province (Pešıć et al. 2006, Erman et al. 2010) but was later on attributed to this species (EsEn et al. 2011). The other species, includ- ing A. romijni, were recorded in Bingöl Province (EsEn et al. 2011). During a survey of the water mite fauna in Siirt Province, Turkey, ive species of the genus Axonopsis were collected, three of which are new records to the Turkish fauna. Descriptions of these species are given in the present paper. Material and Methods During ield work, water mites were collected by hand netting, sorted from the living material on the spot, conserved in Koenike’s luid and dissected in an outside facility (e.g. GErEckE et al. 2007). The specimens were deposited in the research collection of the Biology Department, Fırat University, Elazığ, Turkey. All measurements are given in micrometers. The following abbreviations are used: Ac = acetab- ulum; Cx-I = irst coxae; dL = dorsal length; L = length; I-L-6 = irst leg, sixth segment (tarsus); P-1 = palp, irst segment; vL = ventral length; W = width.

Two subgenera and three species are newly recorded to the Turkish fauna, i.e. Axonopsis (Axonopsis) complanata (Müller, 1776), A. (Brachypodop- sis) guadarramensis Valdecasas, 1981 and A. (Brachypodopsis) inferorum Motaş & Tanasachi, 1947. In addition, two previously reported species from Turkey, A. (Hexaxonopsis) serrata Walter, 1928 and A. (Navinaxonopsis) persica Pešić, 2004 are also found in Siirt Province. Keywords: Acari, Siirt Province, Axonopsis, new records, Turkey
