A new species of aquatic beetle is described, Phanocerus guaquira, which belongs to the Elimidae family and whose diagnostic characteristic is the shape of its pronotum, with grooves and depressions that separate them from the rest of the previously described species. The specimens were collected in litter patches in the Herrera II stream, Yaracuy state, using a device for collecting aquatic insects. Illustrations of the genitalia and other diagnostic characters are included.

Amazonopsis gen. n. is described to include A. theranyi sp. n. from Peru, Venezuela and French Guiana, and A. camachoi sp. n. from Venezuela. The descriptions are accompanied by figures illustrating the male and female habitus of A. theranyi, the male habitus of A. camachoi, and male genitalia of both species. Amazonopsis theranyi exhibits pronounced secondary sexual dimorphism which likewise may be a characteristic of the genus. Amazonopsis males have modifed protarsal and mesotarsal claws, a pair of small spines on the anterior prosternum, and a pair of ventrally directed processes on the posterior metaventrite. Females of A. theranyi display a pair of unique, oval perforations in the cuticle of the pronotum and have unmodifed claws; females of A. camachoi are unknown. Descriptions are furnished of the stream habitats and microhabitats where the study specimens were collected.
