The interstitial groundwater genus Microcharon (Crustacea, Isopoda, Microparasellidae) is highly diversified in southern France. A new species, Microcharon boulanouari n. sp. is described from the Aude River, whereas specimens from the Lachein River in the central Pyrenees are reassigned to another species, M. ariegensis new to Science. Microcharon...

1. Delineation of protected areas for rare subterranean species is a key problem for groundwater biodiversity conservation, because of practical difficulties in implementation. Criteria for site selection are presented that are derived from studies on two remarkable Ostracoda, Dolekiella europaea Gidó, Artheau, Colin, Danielopol & Marmonier (Limnoc...

1. Estimates of species richness obtained from exhaustive field inventories over large spatial scales are expensive and time-consuming. For this reason, efficiency demands the use of indicators as ‘surrogates’ of species richness. Biodiversity indicators are defined herein as a limited suite of taxonomic groups the species richness of which is corr...

The description of Dolekiella europaea gen. nov. sp. nov., a living stygobiotic representative of the Timiriaseviinae subfamily (Ostracoda, Limnocytheridae) is presented. The ostracods were sampled in wells located along the Tech, Têt and Réart Rivers (southern France). The valve morphology (specially the hinge structure) of Dolekiella resembles th...

A new species of Vestalenula is described. Vestalenula carveli, sp. nov. was found in the interstitial habitat of rivers during the PASCALIS European program when sampling three sites on the Aude River and Tech River basins (Roussillon region, southern France). With its large caudal brooding cavity, the presence of an external keel on the right val...

A new species of Acherontacarus (Acari, Hydrachnidia) is described from a well in the south of France. The description is made with the help of images taken with the Environmental Scanning Electronic Microscope. A key to all described species is included. The chaetotaxy of terminal segments of IV‐Leg in male, general morphology of genital field and...

Three males of Cryptocandona vavrai were discovered in geographically distant sites (UK, France, Romania), representing different environments (surface and underground waters). The species may be considered a parthenogen with rare occurrence of single males, the morphology of which was hitherto poorly known. The first complete description of males...
