Zoologica Scripta, Volume 49, Issue 5, Page 614-640, September 2020., 2020 Abstract Clitellata is a major clade of Annelida comprising nearly all freshwater and terrestrial annelids as well as several marine species. We investigated clitellate phylogenetic relationships using transcriptomes sampled from 74 taxa (64 clitellates and 10 polychaetes), including multiple representatives of nearly all major clitellate higher taxa ...

Oogenesis of Helobdella ampullariae (Hirudinida, Glossiphoniidae)
Neotropical Biology and Conservation, 2018 The knowledge of the gametogenesis in Hirudinida is an important tool that allows the understanding of the reproductive cycle. Ovogenesis of Helobdella ampullariae was described based on 30 leeches collected from mantle cavity and lung of Pomacea canaliculata .

Genetic Diversity of Freshwater Leeches in Lake Gusinoe (Eastern Siberia, Russia)
The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014 The study of leeches from Lake Gusinoe and its adjacent area offered us the possibility to determine species diversity. As a result, an updated species list of the Gusinoe Hirudinea fauna (Annelida, Clitellata) has been compiled. There are two orders and three families of leeches in the Gusinoe area: order Rhynchobdellida (families Glossiphoniidae and ...
