The Acanthocyclops kieferi (Chappuis, 1925) complex (Copepoda, Cyclopoida) includes exclusively
stygobitic species, mainly widespread in the cave habitats of south-eastern Europe. A new
species for the group, Acanthocyclops milotai n. sp., collected from pools supplied by percolation
water in a cave in south-western Romania, is described. The new species is distinguished from its
congeners by the following characters: the ornamentation pattern of the basis of the antenna with
four spinules placed in an arch; the coxa of leg 4 with four spinules on its distal margin; furcal rami
divergent, about 2.2 times as long as wide, with the lateralmost, terminal furcal seta 1.14 times as
long as the medialmost one, and these both setiform. Inter-populational variability of some characters
in the new species such as the shape of the anal operculum and the ornamentation of the coxa
of leg P4 are discussed. Furthermore, the characters generally used to differentiate the taxa of the
kieferi group are re-examined and discussed, and a brief description of the adaptive traits of these
species to the groundwater is given. Biogeographical and ecological considerations about the kieferi
species-complex in Romanian groundwater habitats are also mentioned.
