Family BYCHOWSKICOTYLIDAE Lebedev, 1969

Introduction

The polyopisthocotylean genus Tonkinopsis was proposed by Lebedev (1972) for the newly described monotypic species Tonkinopsis transfretanus from the gills of Plectorhinchus cinctus collected in the Gulf of Tonkin, South China Sea. Lebedev (1972) erected the new family Calyxinellidae to accommodate the new genera Tonkinopsis and Calyxinella (now Yamaguticotyla Price, 1959), which were distinguished from other members of his suborder Gastrocotylinea, by the symmetrical haptor and unique male copulatory organ. Lebedev (1986) subsequently lowered the Calyxinellidae to subfamilial status, placing it, along with the Bychowskicotylinae, in the family Bychowskicotylidae (Chisholm et al. 1996).
