The study of several Lake Baikal leech collections offered us the possibility to determine species diversity in the Chivyrkuy Gulf, the biggest one in the lake. As a result, the first information on the Chivyrkuy Hirudinea fauna (Annelida, Clitellata) has been revealed. There are two orders and four families of leeches in the Chivyrkuy Gulf: order Rhynchobdellida (families Glossiphoniidae and P...

The evolutionary patterns of divergence of seven euhirudinean families were investigated by cladistic analysis of 33 euhirudinean species. Oligochaetes, Acanthobdella peledina, and branchiobdellidans were included as outgroup taxa. Cladistic analysis employed 1.8 kb of nuclear 18S ribosomal DNA and 651 bp of mitochondrial cytochrome c oxidase subunit I in addition to morphological data. The use...

Two species of leeches were described from Georgia in the past, Dina ratschaensis Kobakhidze, 1958 Racha-Lechkhumi and Kvemo Svaneti region Trocheta ariescornuta Grosser, Barjadze & Maghradze, 2021 Samegrelo-Zemo region. Both only known typical representatives cave Georgia. Recently, two more genus R. Blanchard, 1894 have been found karst caves this country. These are morphologically si...

Two 60 day experiments on predation behavior of leeches were conducted concurrently. In the first, medicinal leeches, Hirudo orientalis (Utevsky and Trontelj, 2005) were fed to satiation on bovine blood and subsequently transferred into two large opaque plastic containers of equal size but with differing temperatures, 6-7?C and 23-24?C, containing starved Erpobdella octoculata (L.). At the high...

aquatic invertebrates are the major group of freshwater animals in aquatic ecosystems in terms of biology and food chain. this study was conducted to identify benthic communities in four stations of the abgarmeh river (saleh abad, the ilam province) during 2007-2008. in this study eighteen families of benthose such as naididae, tubificidae, lumbricidae, erpobdellidae, gammaridae, haliplidae, co...

Leeches of the genus Dina are one most abundant leech species in running waters Montenegro. This paper described a new yellowish-spotted and medium-sized from Skadar Lake basin Phylogenetic analysis based on COI data reveals that nesemanni sp. nov. is more closely related to D. latestriata Prespa than other yellow-spotted leeches known montane alpine areas Morphologically, can be separated all ...
