Description of both species are based on bright-field microscopy only; it is possible that advanced optical techniques (e.g., DIC) may reveal internal structures so far undetected (e.g., the frontal organ) and/or may provide a better insight on the structure of the very long cylindrical caudal organ (bursa copulatrix in the original description). As the layout of the reproductive system has been demonstrated to be of phylogenetic significance (e.g.,
