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.

Two new species of the subfamily Larainae (Insecta: Coleoptera: Elmidae), Hexanchorus angeli n. sp. and Hypsilara autanai n. sp., are described from Guyana region in Venezuela. We provide habitus photographs, detail drawings of both male and female genitalia, and description of morphological features important for discrimination of the new species. Molecular differences within genera were measured using 816bp fragment of mtDNA gene for cytochrome oxidase c subunit I. Sequence divergences among species are discussed.
