412 species-group names (including 11 replacement names), and 14 genus-group names of the   Alycaeidae   have been introduced to date. Type materials of 85% (336) of the known species and subspecies were examined, a further 5% (19) of the taxa were studied using available non-type material, and for another 6% (22) the original descriptions were sufficiently detailed to evaluate their taxonomic status. Only 3% of the taxa (12) could not be examined. Special attention was paid to the sculpture of the embryonic whorls and the sutural tube-microtunnel system in order to provide a novel classification for this group.In this study 363 taxa (320 species or 43 subspecies) are accepted within the family   Alycaeidae  . Of these, 22 have been described by the lead author and his coauthors in previous publications. In addition, there are 18 species that were formerly classified in    Cycloryx    and now belong to    Pincerna    due to its synonymy with    Cycloryx   . Among the remaining 323 species, 209 (65%) are transferred here to another genus, whilst 114 (35%) have remained in their original genus.Seven genera are accepted. While some questions (e.g., the distinction between    Pincerna    and    Alycaeus   ) remained unanswered, this revision made three main achievements: (1) The    Dicharax    species were identified based on the absence of spiral striation on the entire shell; (2) the    Metalycaeus    species were identified based on the spiral striation of the protoconch; (3) and    Stomacosmethis    was separated from    Alycaeus    based on the extremely short sutural tube.Five nominal species are being synonymised with other species, and eight species are now treated as subspecies. The following replacement names are proposed:    Dioryx   urnula   niosiensis    Páll-Gergely,  nom. nov.  for   Alycaeus   urnula   var.   daflaensis   Godwin-Austen, 1914;    Dioryx   urnula   rotundus    Páll-Gergely,  nom. nov.  for   Alycaeus   urnula   var.   globosus   Godwin-Austen, 1914;    Pincerna   crenilabris   juttingae    Páll-Gergely,  nom. nov.  for    Alycaeus   crenilabris   laevis    van Benthem Jutting, 1959;    Pincerna   crenilabris   korintjiensis    Páll-Gergely,  nom. nov.  for    Alycaeus   crenilabris   latecostatus    van Benthem Jutting, 1959;    Dicharax   conicus   jatingaensis    Páll-Gergely,  nom. nov.  for   Alycaeus   conicus   var.   nanus   Godwin-Austen, 1914;    Metalycaeus   godwinausteni    Páll-Gergely,  nom. nov.  for    Alycaeus   neglectus    Godwin-Austen, 1914; and finally    Metalycaeus   suhajdai    Páll-Gergely,  nom. nov.  for    Alycaeus   varius    Godwin-Austen, 1914.
