Abstract

Two new species of the family Phthiracaridae, Arphthicarus paratinctus sp. n. from the Seychelles, and Atropacarus (Atropacarus) paraclavigerus sp. n. from California, USA are described and figured. A comparison of morphological similarities with the most closely related species is presented. Additional descriptions, morphological remarks and taxonomical notes for seven ptyctimous species: Arphthicarus sculptilis (Niedbała, 1988), Austrophthiracarus diazae (Ojeda, 1985), Mesoplophora (Mesoplophora) parabacilla Niedbała, 2006, Notophthiracarus lienhardi Mahunka, 1996, N. stenotus Niedbała et Corpuz-Raros, 1998, Plonaphacarus semiaciculatus (Mahunka, 2008), and Steganacarus (Rhacaplacarus) brasiliensis (Pérez-Iñigo et Baggio, 1980) were added. In total, 105 species of ptyctimous oribatid mites were determined in material of 1910 specimens from 15 countries – Bangladesh, Brazil, Canada, Colombia, Cuba, Galapagos, Gough Island, Indonesia (Irian), Jamaica, Kenya, Malaysia, Reunion, Seychelles, Tanzania and the USA. Fauna of ptyctimous mites of Bangladesh, Colombia and Gough Island was studied for the first time. New records of ptyctimous mites for Brazil, Canada, Cuba, Jamaica, Malaysia, New Guinea (Indonesia, Irian), Reunion, Tanzania and the USA are also presented. A replacement name for the junior homonym Austrophthiracarus longisetosus Niedbała et Starý, 2015, A. longisetus nom. n. is proposed.
