AB  - Harpacticoid copepods – a diverse and abundant crustacean order in groundwater – have been studied in Romania since the early 20 th century, mainly by the Swiss researcher P. A. Chappuis. The Apuseni Mountains in northwestern Romania are the most studied area, with 31 species and subspecies reported from all types of groundwater habitats, representing half of the species known at the country level. The Padurea Craiului is the most investigated karst unit within the Apuseni, showing the highest number of records (122) and species (28), with the highest diversity of species found in the Cri?ul Repede and Cri?ul Negru river basins. Bihor-Vladeasa is the second most studied area, with 18 species, including cold-stenotherm species like Bryocamptus (Arcticocamptus) cuspidatus cuspidatus and Spelaeocamptus spelaeus. Only two endemic species have been identified in the Apuseni, S. spelaeus (in various groundwater habitats from both Padurea Craiului and Bihor-Vladeasa) and Elaphoidella winkleri (in a single cave within the Bihor-Vladeasa unit). The dataset presented here extends over a period of more than 90 years allowing to evidence the historical research on this group of crustaceans in the Apuseni and to identify the future research directions to enhance the knowledge in groundwater of this emblematic karst region of Romania.

Key words: distribution, diversity, endemicity, groundwater, Harpacticoida.
