Japanese species of the genus Zaitzevia are revised taxonomically. Nine species including one new species, Zaitzevia wakayamana sp. nov. from Honshu (Wakayama Pref.) are recognized in Japanese fauna. All the species are described or redescribed with figures of habitus, elytra, elytral epipleura and male genitalia. Endophallic structures of seven species are described. A key to Japanese species is also given.

A new riffle beetle, Zunielmis pax gen. et sp. nov. , is described from Colombia (Vichada, Puerto Carre\ño, Bita River basin). It can be distinguished from all the other elmids by having large areas of a microgranular mesh (plastron) on the pronotum and elytra, crenulate lateral margin of the latter two, the shorter interocular distance than diameter of each eye, as well as by the characters of the structure of mandibles, the shape and sculpture of pronotum, and the structure ofmesosternum,mesotibiae and elytra. The imagoes were collected on freshwater sponges. The habitat, where the new species was found, is described, and the adaptive meaning of the characteristics of plastron are discussed. Drawings and photographs of the adult habitus, distinctive morphological characters, and male and female genitalia are provided.

The monotypic genus Pagelmis Spangler, 1981 was described from six thousand specimens of Pagelmis amazonica Spangler, 1981 collected with blacklight traps in Ecuador. For many years the known distribution of this genus was restricted to its type-locality, and recently it was recorded in Venezuela, Suriname and Brazil (Roraima State). Now, 40 years after the description of the genus, we describe the second Pagelmis species, based on male and female collected in the Amazon forest (Amazonas State, Brazil).With the description of the second species in the genus we provide an emended diagnosis of Pagelmis. Since adults of this genus were previously collected only in light traps, no habitat information was known. We collected adults of the new species in the first- and second-order streams with black, acidic water and sandy streambeds. The main substrates available in these streams were leaves and roots of riparian vegetation.

The genus Onychelmis Hinton, 1941 was for a long time regarded as a small taxon with only three known species distributed in the Andes. A study of new material from Ecuador, using morphological and molecular data, has resulted in the discovery of five new species: Onychelmis lenkae sp. nov., O. lobata sp. nov., O. minor sp. nov., O. onorei sp. nov. and O. splendida sp. nov. We also revised the entire genus and redescribed the three known species, O. longicollis (Sharp, 1882), O. leleupi Del\ève, 1968 and O. whiteheadi Spangler \& Santiago, 1991. Habitus photographs of adults are provided, together with line drawings of male and female genitalia, and schematic illustrations of the distribution of femoral tomentum for each species. DNA sequences for barcoding the COI mtDNA fragment were used to support species delimitation and to suggest possible relationships among species. The revision includes a key to adults of all species of Onychelmis and notes on the biogeography of the genus, with an updated distribution map.

A new minute riffle beetle genus Ictelmis gen. nov. and the type species Ictelmis martae sp. nov. are described from Ecuador. The description is supported by characteristic morphological features and DNA barcoding data, drawings and habitus photographs are provided. Based on molecular data and morphology it is suggested that Ictelmis is closely related with Onychelmis Hinton, and Notelmis Hinton.

A new species of Stethelmis, S. shepardi sp. nov., is described for Patagonia, Argentina from adults of both sexes. A full description and illustrations of both the adult and the larva of the new species are provided with comments on its habitat and distribution. Adults of the new species are compared with those of S. kaszabi (Hinton 1970) and S. chilensis (Hinton 1945). The larva of S. shepardi is compared with that of S. kaszabi, the other Stethelmis larva described. We also describe and illustrate for the frst time the male genitalia of S. kaszabi. A key to the known species of Stethelmis is also included.

The genus Austrolimnius Carter \& Zeck has its greatest known diversity in Oceania, but its fauna in the Americas is poorly known. In this paper, two new species\—Austrolimnius uncatus sp. nov. and A. bocainensis sp. nov.\—are described and illustrated based on adult specimens collected at Serra da Bocaina National Park, S\ão Jos\é do Barreiro Municipality, S\ão Paulo State, and Nova Friburgo Municipality, Rio de Janeiro State, Brazil. Austrolimnius uncatus sp. nov. is characterized by the long setae on the mesotarsus, the medial expansion of the hind tibiae, and the hook-like shape of the male genitalia. Austrolimnius bocainensis sp. nov. can be recognized by the absence of setae on the mid-tarsus, the cylindrical hind tibiae, and the slightly curved genitalia with few setae. A pictorial key for the Brazilian species of the genus is given. New records of Brazilian species of the genus are reported.
