Taxonomic reintroduction of (Taphrinales, Ascomycota) associated with as one of five well defined European species colonizing alders.

Phylogenetic analysis of four DNA regions (ITS, LSU, mtSSU and ) supported the existence of five European species which colonise in Europe. In addition to previously well-defined species, is, for the first time recognised, by molecular study as a species related to . Analysis of publicly available sequences of barcoding regions suggested that is only associated with and no other species colonize this host tree.

sp. nov., a new spider riffle beetle from Sarawak, and new distribution records for Kodada, Jäch & Čiampor based on DNA barcodes (Coleoptera, Elmidae).

(Coleoptera, Elmidae), a new spider riffle beetle from the Kelabit Highlands (Sarawak, northern Borneo), is described. Illustrations of the habitus and diagnostic characters of the new species and the similar, polymorphic Kodada et al. are presented.

, a new spider riffle beetle species from Borneo, redescription of Jäch including a description of the larva and new distribution data for Jäch using DNA barcodes (Coleoptera, Elmidae).

(Coleoptera, Elmidae) a new spider riffle beetle discovered from northern Borneo (Brunei; Sabah and Sarawak, Malaysia) and the larva of Jäch are described. Illustrations of the habitus and diagnostic characters of the new species and the similar and highly variable are presented. Differences to closely related species, based on DNA barcodes and morphological characters, are discussed.

Four new species of Sharp from Ecuador (Coleoptera, Elmidae) with DNA barcoding and notes on the distribution of the genus.

The riffle beetle genus Sharp, 1882 is distributed from Mexico to Argentina, forming an important component of the freshwater invertebrate fauna of Latin America. With 21 described species, represents one of the most speciose Larainae genera, but its real diversity is likely much higher. We analysed material from a relatively small area in Ecuador, resulting in the first record of for Ecuador and discovery of four new species and one subspecies: , , , and For delimiting and characterizing species, both morphological and molecular (mtCOI DNA barcodes) data were used.
