This dataset contains the digitized treatments in Plazi based on the original journal article Bartsch, Ilse (2018): Freshwater halacarid mites (Acari: Halacaridae) from Madagascar - new records, keys and notes on distribution and biology. Bonn zoological Bulletin 67 (2): 79-99, DOI: 10.20363/BZB-2018.67.2.079, URL: http://dx.doi.org/10.20363/bzb-2018.67.2.079
Abstract. Four freshwater halacarid species were previously recorded from Madagascar. They had been extracted from sandy deposits at the banks of streams and creeks. Recently another two species were found, namely Porohalacarus alpinus and Soldanellonyx monardi. On the basis of individuals of these two species, as well as of additional material of the four formerly recorded species (Limnohalacarus cultellatus, Limnohalacarus novus, Lobohalacarus weberi, and Ropohalacarus pallidus), morphological characters are added to previous descriptions and the male of P. alpinus is described. A key is given to adults of Madagascar freshwater halacarid genera. Morphological differences between the presently known African freshwater halacarids are outlined. Geographical and biological data of the six species from Madagascar are presented. All genera and most of the species have world-wide distributions.
Key words. Halacaroidea, riverine sediments, taxonomy, biology, geography.
