Okalia necopinata sp. nov., from Sarawak, northwest Borneo, Malaysia, is described and illustrated along with an identifcation key. The standard barcoding fragment of the mitochondrial gene coding for cytochrome c oxidase subunit I (COI) was used together with morphological characters to delimit the taxonomic boundaries of the two known species, which live in shallow streams fowing through dense primary forests in limestone areas in Pahang (West Malaysia) and Sarawak (East Malaysia). The majority of all examined Okalia are fightless. Morphological distinguishing characters are the length of the granulated ffth elytral interval, the elytral and pronotal punctation, the aedeagal morphology, and the distal portion of the ovipositor.

Potamophilus kelabitensis sp. nov., a new rife beetle (Coleoptera, Elmidae) discovered in the Kelabit Highlands (northern Sarawak) and Sapulut environment (southern Sabah), is described. Illustrations of the habitus and diagnostic characters of the new species are presented. Diferences from the type species P. acuminatus (Fabricius, 1792) from the Palaearctic region, based on DNA barcodes and morphological characters, are discussed. Selected morphological characters of all known species of Potamophilus from Vietnam, Myanmar, and Papua New Guinea are also compared with the new species. The systematic position of the genus relative to other sympatric genera of the subfamilies Larainae LeConte, 1861 and selected Elminae Curtis, 1830 belonging to three tribes is discussed based on phylogenetic trees inferred from the mitochondrial COI and nuclear ArgK as well as 18S rRNA gene sequences.

Ten new species of the genus Ancyronyx Erichson, 1847 from Sulawesi are described along with additions to the original description of Ancyronyx raffaelacatharina J\äch, 2004. Ancyronyx vincentarnoldi sp. nov. belongs to the Ancyronyx variegatus (Germar, 1824) species-group; Ancyronyx breviparamerus sp. nov., Ancyronyx hafti sp. nov., Ancyronyx henningi sp. nov., Ancyronyx konjo sp. nov., Ancyronyx longiparamerus sp. nov., Ancyronyx skalei sp. nov., Ancyronyx schoedli sp. nov., Ancyronyx tobada sp. nov. and Ancyronyx toraja sp. nov. belong to the Ancyronyx patrolus Freitag \& J\äch, 2007 species-group. Diagnostic characters are illustrated by photographs of habitus, line drawings of genitalia and by scanning electron micrographs. An updated checklist of all Ancyronyx species including distribution data is provided. Cox1 mitochondrial DNA sequences were amplified for nine of the species listed above and used to construct a haplotype network by the application of statistical parsimony. The molecular data support our morphological species concept except for two taxa that showed little genetic distance, but were distinguishable by the male genitalia.

Four species have been recognized in the genus Jolyelmis Spangler \& Faitoute; all collected at isolated table mountains, mostly in cool stenothermal hypocrenal streams. The known distribution of the genus is confined to Venezuela, and each species is here reported as endemic for the respective table mountain where it has been found. Samples from Chur\í-tepui and Mount Roraima in south-eastern Venezuela contained numerous adults and larvae of Elmidae among which is a new species, Jolyelmis spangleri, which is here described. The new species is illustrated and keyed with all other Jolyelmis, and new distributional data for J. reitmaieri\ {\v C}iampor, Jr. \& Kodada are included. Molecular analysis of partial cytochrome oxidase subunit I (cox1) confirmed conspecific life stages for two species: J. spangleri and J. reitmaieri. The larva of each species is described and illustrated, and the generic diagnosis for Jolyelmis larvae is provided. Among the known larvae of South American Elmidae, larvae of the genus Xenelmis Hinton appear to be the most similar. Morphological similarities are discussed. Habitats of adults and larvae are briefly described and illustrated by photographs.

Two mitochondrial (cytochrome oxidase subunit I, 16S RNA) and one nuclear (18S RNA) gene fragments were used to analyse relationships within the Oulimnius tuberculatus species group. The results of molecular data analysis are compared with morphological characters, and the distributional patterns and taxonomic status of recognized taxa are addressed. Based on molecular data, Oulimnius perezi is re-validated as a distinct species, and the discovery of a possible new species from northwest Italy is reported. The possible origins and times of speciation within the species group are discussed.
