New records of water mites of the genus Atractides Koch, 1837 (Acari: Hydrachnidia, Hygrobatidae) from South Africa are presented. Five species new to science, Atractides cooki, A. dracomontanus, A. meridianus, A. capensis and A. neoscutifer are described; a first description of the male is given for A. pulcher K. Viets, 1956 and A. assimilis K.O. Viets, 1964. A key to the species of Atractides from South Africa is presented. Copyright © 2011 Magnolia Press.

Four species of water mites (Acari, Hydrachnidia) were collected in 2010 during an Italian speleological expedition to caves of the Ha Giang region in northern Vietnam from rimstone pools or other tiny accumulations of percolating water. Four taxa new to science are described, representing the families Torrenticolidae (Torrenticola anophthalma nov. sp., Sty-gotorrenticola coniseta nov. gen., nov. sp.), Limnesiidae (Raptorhydracarinae subfam. nov., Raptorhydracarus tomasini nov. gen., nov sp.) and Athienemanniidae (Africasia vietnamitica sp. nov.). Most of these taxa show striking morphological adaptations to subterranean life. Copyright © 2014 Magnolia Press.

Selected water mite species of the family Aturidae are revised. The following synonyms are established: Aturus intermedius serrata K. Viets, 1922 = A. asserculatus Walter, 1906; A. lelgioensis Rensburg, 1971 = A. natangensis Protz, 1900; A. oudemansi Besseling, 1932 = A. intermedius Protz, 1900. The proposal of E. Angelier (1965), to synonymize A. paucisetus Motaş & Tanasachi, 1946 with A. brachypus K. Viets, 1934 is rejected. Aturus elongatus Walter, 1927 (described after females, type material heavily damaged) and Ljania bipapillata subterranea Schwoerbel, 1964 (no type material available, no type locality defined) are considered as species incertae. Ljania macilenta longissima Schwoerbel, 1962 is redescribed and elevated to species rank. Two species of the genus Kongsbergia are described as new to science from interstitial habitats in the Central Mediterranean: K. albanorum sp. nov. from Western Sicily and K. jaentschi sp. nov. from Sicily and Sardinia. Woolastookia basilicalabrica sp. nov. is described from mountain streams in Southern Italy. Numerous new records are given, extending noteworthy the known distribution area of several species in Southern Europe. Aturus rotundus Romijn, 1921, Kongsbergia dentata Walter, 1947 and K. simillima K. Viets, 1949 are recorded for the first time from Italy, K. pectinigera Motaş & Tanasachi, 1946 from France and Italy; first records from Corsica are given for Aturus intermedius and A. spatulifer Piersig, 1904. Lectotypes are designated for Aturus asserculatus Walter, 1906; A. asserculatus serratus K. Viets, 1922; A. oudemansi Besseling, 1932. Copyright © 2014 Magnolia Press.

A list is given of the water mite material of the genus Atractides Koch, 1837 (Acari: Hydrachnidia, Hygrobatidae) deposited in the Muséum national d'Histoire naturelle in Paris. Atractides allgaier Gerecke, 2003 and A. remotus Szalay, 1948 are recorded for the first time for France. From running waters in central-southern France, Atractides marsus n. sp. and A. angelieri n. sp. are described. Copyright © 2012 · Magnolia Press.

The distribution patterns of Alpine crenic meiofauna were studied using a standardised sampling procedure at 110 springs, evenly distributed across both carbonate and siliceous rocks in Trentino (northern Italy). Spring altitude ranges between 170 and 2800 m a.s.l. One hundred and thirty-eight taxa (mainly identified at species level), belonging to the Annelida (39), freshwater Acari (57), Copepoda (24), and Ostracoda (18) were found in springs of the investigated area. Using Canonical Correspondence Analysis, spatial patterns of meiofaunal assemblages at the regional scale were best explained by altitude, water chemistry (mainly related to geology) and water-flow regime; the role of microhabitat structure and anthropogenic disturbance as environmental descriptors was of minor importance.
