A detailed morphological description of the larval stage of Acentrella glareosa sp. nov. and Acentrella charadra sp. nov.from the genus Acentrella Bengtsson, 1912 is given. Their differential diagnoses are provided with regard to other Palaearctic representatives of the genus. A. glareosa sp. nov. can be distinguished from the rel ated species by the unique shape of maxillary palp, the arrangement of the bristles on it’s legs (the presence of bilateral ciliation and the second ventral row of tibial bristles) and vestigial paracercus. A. charadra sp. nov. is characterized mainly by the presence of apparent subapical bristles on the tarsal claws, the shape of it’s leg bristles (bilateraly ciliate on femora and tibiae, a row of tarsal bristles missing), the unique shape of the labial palp and vestigial paracercus. The generic concept of Acentrellaand its historical development is summarized.
