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.

Te rife beetle genus Hexanchorus Sharp, 1882 is distributed from Mexico to Argentina, forming an important component of the freshwater invertebrate fauna of Latin America. With 21 described species, Hex-anchorus represents one of the most speciose Larainae genera, but its real diversity is likely much higher. We analysed material from a relatively small area in Ecuador, resulting in the frst record of H. cordillierae
for Ecuador and discovery of four new species and one subspecies: Hexanchorus virilis sp. n., Hexanchorus\ rostratus sp. n., Hexanchorus shepardi sp. n., Hexanchorus onorei sp. n. and Hexanchorus onorei sagittatus ssp. n. For delimiting and characterizing species, both morphological and molecular (mtCOI DNA barcodes) data were used. A distribution map of Hexanchorus species is provided based on published records.
