The riffle beetle genus Hexanchorus Sharp is, with 25 known species, the most speciose genus of the subfamily Larainae in the Neotropics and the second largest globally. An analysis of its phylogeny, based on two mitochondrial (COI, 16S) and two nuclear (18S, 28S) markers, including Hexanchorus-like, but morphologically distinct specimens, supported presence of an unknown genus. The new genus, Rumilara gen. nov., is described here with four new species (R. obscura sp. nov., R. paterna sp. nov., R. riberai sp. nov., R. suppressa sp. nov.) and their larvae. The separate position of the new genus is, beside molecular differences, well substantiated by the morphology of adults (the absence of sexual dimorphism, structure of the pronotum) and larvae (pleurites never reaching to sixth abdominal ventrite). H. sagittatus stat. nov. is elevated to species rank based on molecular data, and Rumilara leleupi (Del\ève) comb. nov. is transferred from the genus Hexanchorus and redescribed, based on its morphology.

In this study, the new genus Spanglerelmis Polizei \& Bispo is described; Microcylloepus ochus Hinton, 1940 is synonymized with Microcylloepus femoralis Hinton, 1940, and transferred to the new genus; and two new species, S. xiririca gen. et sp. nov. and S. timburi gen. et sp. nov. are described. The new genus can be characterized by the combination of the following characters: 1) pronotum without transverse, longitudinal or oblique impressions, sulci or gibbosities on disc; 2) elytra with a carina on interval III and two sublateral carinae on intervals V and VI; 3) mesoventrite with sides strongly raised; and 4) femora with an oblique belt of tomentum dorsally and a transverse belt ventrally. The specimens of the two new species were collected mainly in riffes of unimpacted streams in the Atlantic Forest in S\ão Paulo State, Brazil. Scanning electron microscope images, an identifcation key for the genus and habitat notes are also presented.

A new riffle beetle, Zunielmis pax gen. et sp. nov. , is described from Colombia (Vichada, Puerto Carre\ño, Bita River basin). It can be distinguished from all the other elmids by having large areas of a microgranular mesh (plastron) on the pronotum and elytra, crenulate lateral margin of the latter two, the shorter interocular distance than diameter of each eye, as well as by the characters of the structure of mandibles, the shape and sculpture of pronotum, and the structure ofmesosternum,mesotibiae and elytra. The imagoes were collected on freshwater sponges. The habitat, where the new species was found, is described, and the adaptive meaning of the characteristics of plastron are discussed.
