Pseudohesperocyclops loeiensis, new genus, new species, was collected from plastic containers that receives water from a 120-meter-deep well drilled into Cretaceous formations composed of sandstone, claystone, siltstone, conglomerate, and gypsum in Loei province, northeast Thailand. The new genus differs from the related genera Metacyclops Kiefer, 1927 and Hesperocyclops Herbst, 1984, by the shape of the female genital double somite, the swimming leg armature formula, and the P4 Enp number of segments, as well as on the form of P5. The new species shares several characters with Metacyclops cushae Reid, 1991, and Metacyclops thailandicus Boonyanusith, Sanoamuang & Brancelj, 2018, which are moved to this new genus. All three members of the new genus differ in the shape of the female genital double somite, the anal operculum, the furcal rami, and the P1 Enp-2 apical spine. Detailed comments on the regional ecology and sampling methods are included to promote collecting samples from other, less common habitats. Key words. artesian well, extreme habitat, groundwater, Pseudohesperocyclops, Mars conditions, stygobionts
