Recorded from Ireland by Walker (1835). Ceratacis flavipes and C. laricis seem to differ only in the structure of the male A4 which is unusually large in C. laricis . As these two rare species have been found together on the same locality and date these are possibly two forms of the same species (i.e. of C. laricis ).
