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 endophallus of the genus Zaitzeviaria is characterized by membranous sac with several bladders covered by spines. The endophallic structures of most members are observed in detail and their homologies are examined. Five Japanese members of the genus including a new species are reviewed: Z. sotai sp. nov., Z. ovata (Nomura), Z. brevis (Nomura), Z. gotoi (Nomura) and Z. kuriharai Kamite, Ogata et M. Sat\ô. Zaitzeviaria sotai sp. nov. is collected from Shimane and Tottori Prefectures including Oki Islands.

The adult and larva of Typhloelmis Barr, a new genus of eyeless, stygobiontic elmid from springs in west-central
Texas, and the adults of three new species, Typhloelmis caroline Barr, Typhloelmis finegan Barr, and Typhloelmis sanfelipe Barr, are described, diagnosed, and illustrated. Taxonomic couplets are provided for the insertion of the new genus intoexisting adult elmid generic keys, and an adult key to the species of Typhloelmis is included. Stygobiontic elmids are reviewed, and the uniqueness of Typhloelmis is discussed. Typhloelmis is the first stygobiontic elmid genus reported from the Nearctic ecozone and is the seventh described worldwide. It is only the second elmid genus known to be anophthalmic (completely eyeless). The Edwards-Trinity Aquifer and the spring habitat in which the genus and species occur are described in detail, and potential threats are discussed.
