| abstract | The present study is based on ptyctimous oribatid mite material (Acari, Oribatida) collected in Nepal in 1980 and 1995. A list of identified taxa, including 18 species from 12 genera and five families, is provided; of these, Apoplophora pantotrema, Euphthiracarus carinatus, Phthiracarus boresetosus and Ph. setosus are recorded for the first time in the Nepalese fauna. Two new species of the genus Plonaphacarus (Steganacaridae) are described: P. diutissimus Niedbała sp. nov. differs from P. machadoi (Balogh, 1958), P. tanzicus (Mahunka, 1993), P. ngongi Niedbała, 2001 and P. styphelos Niedbała, 2001 by the length of lamellar and notogastral setae, number of notogastral lyrifissures, and the morphology of setae d on leg femora I; P. pugionis Niedbała sp. nov. differs from P. kaluzi Niedbała, 2013 by the morphology of sensilli, arrangement of notogastral setae c1–3, length of subcapitular setae h, morphology of adanal setae ad2, and the localization of setae d on leg femora, and from H. similis Niedbała, 2000 by the shape of sensilli, rostral and notogastral setae and arrangement of notogastral setae c1-3. The supplementary description of Euphthiracarus carinatus Liu, Wu & Chen, 2011 (Euphthiracaridae) is given. |
