Finally Brinkmann redescribed the species in details in 1942 [1] from material collected off Norway and Sweden.

The haptor, at the posterior end of the body, bears eight clamps arranged as two rows of four.

The first molecular sequences obtained from Chimaericola leptogaster suggested that the Chimaericolidae were a basal group within the Polyopisthocotylea.

Several organs have been investigated in details: vaginae,[6] clamps,[7] digestive system,[8] and spermiogenesis and spermatozoa.

[9] These ultrastructural results have confirmed the basal position of the species in comparison to marine Polyopisthocotylea.
