Nomenclature changes in the mite families Neopygmephoridae and Pygmephoridae (Acari: Heterostigmata: Pygmephoroidea) with redescription of two little known species Author Khaustov, Alexandr A. text Zootaxa 2011 2809 47 57 journal article 10.5281/zenodo.201298 9a7a208a-8c53-47c7-9904-1e8197f81d5d 1175-5326 201298 Bakerdania montana ( Willmann, 1956 ) Bakerdania ptilophora Savulkina, 1978 : 136 , figs. 33-36. syn. nov. I examined female holotype of Bakerdania ptilophora Savulkina, 1978 described from Byelorussia ( Savulkina 1978 ). The specimen is damaged, without left setae c 1 and c 2. But all other setae are not damaged. Comparison of holotype of B. ptilophora with the description of B . montana ( Willmann, 1956 ) and redescription of of this species by Mahunka (1970) revealed their conspecificity. Therefore I consider B. ptilophora syn. nov as a junior synonym of B. montana . Material examined . Female holotype of B. ptilophora Savulkina, 1978 , BYELORUSSIA : Brest Distr., Lunetsk Reg., vicinity of Krestunov, from the nest of Myodes glareolus Schreber ( Rodentia : Cricetidae ), 17 April 1968 , coll.
