Potamophilops bostrychophallus Maier, 2013, is reported from French Guiana, new country record. The genus has a peri-Amazonian distribution. New locality records are given for P. cinereus (Blanchard, 1841) and P. bragaorum Fernandes \& Hamada, 2012.

Here we present the first published record of a laraine elmid from Suriname, which represents a new species \– Hexanchorus bifurcatus sp. nov. Specimens were collected from the summit of Tafelberg, a table mountain near the Wilhelmina Range of Suriname. This species can be distinguished from all other Hexanchorus by the bifurcate elytral apices and median projection of the third abdominal ventrite of the female, as well as the distinctive male genitalia. Habitus photos, illustrations of the genitalia, a distribution map, notes on habitat, and comparative diagnoses are provided.

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.
