The genus ''Lethacotyle'' is special in that its members have no clamps on their posterior attachment organ or haptor, in contrast to most polyopisthocotylean Monogenean which have clamps.[Hayward, C. (2005). Monogenea Polyopisthocotylea (ectoparasitic flukes). In K. Rohde (Ed.), Marine Parasitology (pp. 55-63): CSIRO, Collingwood, Australia & CABI, Oxon, UK.] This is reflected in the etymology of the name, which, according to Manter & Price[ is "from ''letha'' = forgetting, and ''cotyle'' = cup, and refers to the absence of clamps".
