Cryptic taxonomic diversity and high-latitude melanism in the glossiphoniid leech assemblage from the Eurasian Arctic.

The family Glossiphoniidae is a diverse and widespread clade of freshwater leeches, playing a significant role in functioning of aquatic ecosystems. The taxonomy and biogeography of leeches from temperate, subtropical, and tropical regions attracted much attention of zoologists, while their taxonomic richness and distribution in the Arctic are poorly understood. Here, we present an overview of the Eurasian Arctic Glossiphoniidae based on the most comprehensive occurrence and DNA sequence datasets sampled to date.

A DNA barcode reference library for endemic Ponto-Caspian amphipods.

The Ponto-Caspian region is an endemicity hotspot that harbours several crustacean radiations, among which amphipods are the most diverse. These poorly known species are severely threatened in their native range, while at the same time they are invading European inland waters with significant ecological consequences. A proper taxonomic knowledge of this fauna is paramount for its conservation within the native region and monitoring outside of it.

Two new species of the genus Victoriopisa Karaman amp; Barnard, 1979 (Crustacea: Amphipoda: Eriopisidae) from mangrove communities of Vietnam with a review of previous records.

Two new mud-dwelling amphipod species of the genus Victoriopisa Karaman Barnard, 1979 (Crustacea: Amphipoda: Eriopisidae) are described from the mangrove habitats of the Cn Gi Mangrove Biosphere Reserve and the estuary of the Be River, Vietnam. Both species are characterized by an anteroventral margin of the head being entire, the presence of eyes, the absence of deep excavation on propodus (palm) and well-marked excavation on dactylus of gnathopod 2, relatively long and slender distal segment of uropod 3. The combination of these features clearly separate the newly discovered species from Victoriopisa ovata (Dang Le, 2005) described from Hi Phng, North Vietnam, and other congeneric species.
