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.

The three genera and four species of Larainae (Elmidae) previously described from Australia are reviewed, and one new genus and seven new species are described: Australara glaisteri gen. et sp. nov., Ovolara lawrencei sp. nov., Ovolara monteithi sp. nov., Stetholus carinatus sp. nov., Stetholus longipennis sp. nov., Stetholus metatibialis sp. nov., and Stetholus woronora sp. nov. A lectotype is designated for Hydora laticeps (Carter \& Zeck), and the first new collection records of the species are reported since its description in 1932. The occurrence in Australia of Potamophilinus papuanus Sat\ô, described from Papua New Guinea, is reported. A key to the species, photographic images of the external morphology and male genitalia, distribution maps, and habitat and behavioral information, when known, are provided for all twelve species of Australian Larainae.

A third species of Amazonopsis Barr, 2018, Amazonopsis cerdani Barr and Cerdan, new species (Coleoptera: Elmidae), is herein described from French Guiana. One female paratype of Amazonopsis theranyi Barr from Peru is tentatively reassigned to A. cerdani as a non-paratype. Photographic images of the male and female habitus, and the male genitalia, are provided, as is a distribution map and a key to the species.\ Amazonopsis cerdani differs from A. theranyi from Peru and Amazonopsis camachoi Barr from Venezuela by the presence of prominent spines on protarsomeres 1\–4 of males, among other characters. The habitat of this species is small, shallow, lowland streams with sandy-silty substrates and low flow. Specimens were collected from unconsolidated leaf litter in depositional areas, and from stick and leaf packs lodged in the current. Genetic analysis conducted on three specimens from two localities, a male and two females, showed that they are conspecific.

Austrolimnius cleidecostae sp. nov. is one of the smallest species of Elmidae from the Neotropical region. The new species is described and illustrated based on male and female specimens. This species represents the first record in Elmidae of mandibles with an articulated, sclerotized process on inner subapical edge. The specimens were collected from streams in the Atlantic rainforest of S\ão Paulo and Santa Catarina, and habitat notes are given. An updated key for the Austrolimnius Carter \& Zeck, 1929 of Brazil is provided. Austrolimnis browni Hinton, 1971 and A. musgravei Hinton, 1939 are recorded for the first time from Brazil.

Hintonelmis is a South American genus of Elmidae, comprising 11\ species. Two further new species are here described and illustrated: Hintonelmis guianensis sp. nov. from Guyana, and Hintonelmis roellae sp. nov. from Brazil, can be distinguished from all other known members of the genus by their general colour pattern, some characters of pronotal and elytral sculpture, and the morphology of the male genitalia. The type material is deposited in the Natural History Museum,\ London, UK and Museum of Zoology of the University of S\ão Paulo, S\ão Paulo, Brazil. New distributional data for species of Hintonelmis are\ presented for the South of Brazil, Bolivia, Ecuador, and Guyana. We also\ provide an updated key for the genus species.

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.

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.

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.
