Cylloepus dimorphus Shepard, Sites, and Rodrigues, new species (Elmidae) is described from Brazil with a sexually dimorphic abdominal ventrite 5. Males have a protruding lobe on each side of the apex of ventrite 5. Females lack the lobes and are not distinguishable from congeners.

Material belonging to the genus Notelmis Hinton y Onychelmis Hinton from different localities from Colombia are evaluated. Two species of Notelmis (N. bifoveolata and N. nodipes) and one of Onychelmis (O. leleupi) are recorded in this country for the first time. The species have been previously found in Ecuador, Panama and Costa Rica. The distribution ranges for the genera Notelmis, Onychelmis, and for the species O. longicollis are also expanded for Colombia. Specimens are mainly located in the Andean natural region between altitudes of 96 and 2,700 meters above sea level. The information is supplemented with illustrated taxonomic keys for identification of the species, distribution maps, and ecological data for the sampling locations.
