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 Satô, 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.

The family Elmidae is represented by a single genus Hydora Broun in New Zealand; they are the most abundant Coleoptera encountered in streams there. There are nine previously described species of Hydora, six from New Zealand, to which we add Hydora musci sp. nov. based on larvae and adults. Hydora musci can be distinguished from all remaining New Zealand species by the following characters: adult with pronotum with weak lateral transverse depression, pronotal lateral carina incomplete extending from posterior margin approximately two-thirds anteriorly, sublateral longitudinal carina less than one-third of the average carina length; elytral punctate striae poorly developed, elytral setae no longer than one-third width of eye, outer surface of mesotibia polished, surface of metatibia not polished; larva with thoracic and abdominal segments bearing single dorsal and lateral protrusions (often reduced), tooth absent on anterior margin of head, laterotergites complete on abdominal segments I and II, complete to incomplete on segments III to IV. Most specimens of H. musci were found in stable tributary streams containing bryophytes in the Arnold River Catchment 31 km inland from Greymouth on the West Coast of the South Island. Larvae are grazers that co-exist with adults at the stream margins and in splash zones associated with bryophytes attached to large boulders. A catalogue of the world Hydora species is included, and lectotypy is established for the following New Zealand species: Hydora subaenea Broun, Hydora picea (Broun), Hydora obsoleta Broun, Hydora nitida Broun, Hydora lanigera Broun and Hydora angusticollis (Pascoe).

The genus Hydora (Coleoptera: Elmidae), previously known only from New Zealand and Australia, is reported from southern Chile and Argentina for the first time. Two new taxa, Hydora annectens, n. sp., and Hydora lenta, n. sp., are described, keyed, and compared with New Zealand congeners; their distinguishing characters and typical biotopes are illustrated. The known distributions of the new taxa are plotted on a map.

The larval stages of the riffle beetle Hydora annectens Spangler and Brown are described and
illustrated for the first time. They are compared to Hydora larvae from New Zealand. A key to the
larvae of the New World genera is given. The distribution of known species of Larainae is
synopsized and a checklist of genera and species is given.
