| Abstract |
In 131 marine, brackish, limnic and terrestrial species of the superfamily Monhysteroidea the following characters have been studied and evaluated phylogenetically : structure of the cuticle ; presence of ocelli ; structure of the amphids ; number, structure and length ratio of the cephalic setae ; presence and postembryonic development of subcephalic setae ; structure of the buccal cavity ; presence and position of the excretory gland and its opening ; number of testes ; position of the testes and the ovary relative to the intestine ; structure of the tail. As a result of this study an argumentation scheme is presented to demonstrate the phylogenetic relationship between the three families of the Monhysteroidea. |
