The genus Herpetocypris Brady & Norman, 1889has a wide distribution in most of the zoogeographical regions except in theNeotropical Region, where only three species have so far been found ? these beingH. reptans (Baird, 1835), H. chevreuxi (Sars, 1895) and H. pectinata Brehm, 1934. We here reportthe first record of Herpetocypris helenae G. W. Müller, 1908 from the Neotropical Region, andprovide a complete revised description and illustration of thevalves and soft parts of this species, as well as information on ecological factorsaffecting its distribution and aspects of morphological variability of itsvalves.
