The genus\ Hydora\ (Coleoptera: Elmidae), previously known only from New Zealand and Australia, is reported from southern Chile and Argentina for the first time. Two new taxa,\ Hydora\ annectens, n. sp., and\ Hydora\ lenta, n. sp., are described, keyed, and compared with New Zealand congeners; their distinguishing characters and typical biotopes are illustrated. The known distributions of the new taxa are plotted on a map.

Here we describe a new genus, for a new species of riffle beetle, Hypsilara royi gen. n. and sp. n., from the tepui Cerro de la Neblina in southern Venezuela. This new genus can be distinguished from all other laraine genera by its small size (ca. 4.5 mm) and the presence of a shallow, wide, V-shaped groove across the apical third of the pronotum. An updated key to the genera of Western Hemisphere Larainae is provided, along with information on habitat and collection methods for this taxon.
