The genus Hexacylloepus extends from the Neotropical region to the southwestern United States of America. At present, 25 species are known from 20 countries, with no new species proposed since 1972. In this paper, we describe and illustrate 18 new species (H. barrae; H. calori; H. casariae; H. froehlichi; H. geiseri; H. grandis; H. iassu; H. keitai; H. maierae; H. manauara; H. metapa; H. phalluspilosus; H. shorti; H. taylorae; H. thoracica; H. tibialis; H. ubirajarai; H. zaninii), from eight countries and give the first records of the genus from Suriname and Guyana.

Neocylloepus Brown, 1970 and Pilielmis Hinton, 1971 are Neotropical genera of riffle beetles, mainly distributed in Central America and the north of South America. These genera are here reported for the first time from Venezuela, and a new species, Pilielmis shepardi sp. nov. is described and illustrated. The type material is housed in Museu de Zoologia da Universidade de S\ão Paulo, S\ão Paulo, Brazil (MZSP), Natural History Museum, London, UK (BMNH), Museo del Instituto de Zoolog\ía Agr\ícola, Maracay, Venezuela (MIZA), Michael A.

Elmidae is one of the most diverse families of aquatic beetles, with more than 1500 species in 148 genera. Cylloepus is the genus with the most species in Americas, with 52 species and 2 subspecies currently known. The genus is easily recognised by external morphology; body elongate, pronotum with a longitudinal impression on the disc and elytra striate and punctate. In this paper, based on the study of several international reference collections, we propose two new combinations, and describe two new species of Cylloepus (C. bispoi sp. nov. and C. segurae sp. nov.) from Ecuador and Bolivia.
