A review of the subfamily Eliminiinae (Cirripedia: Thoracica: Austrobalanidae), including a new genus, Protelminius nov., from the Oligocene of New Zealand Author Buckeridge, John S. Author Newman, William A. text Zootaxa 2010 2349 39 54 journal article 10.5281/zenodo.275597 67a85b62-4ece-46c9-a8bc-b0f7fa95177f 1175-5326 275597 Genus Elminius Leach, 1825 Elminius Leach, 1825 : 210 . — Darwin, 1854 : 345 . — Ross, 1970 : 9 . — Newman and Ross, 1976 : 52 Elminius ( Elminius ) Buckeridge, 1983a : 353 . Diagnosis: Four-plated elminiine lacking distinct external ribbing; parietes smooth internally (“inflected inner basal margin” absent), but with fine striae at basal edge; scutum lacking adductor ridge, articular ridge prominent, tergum with spur removed from basi-rostral angle; scutum and tergum often fused together by internal secondary calcification. Distribution and age: Littoral, low energy environments. Recent: Southern South America . Type : Elminius kingii Gray, 1831: 13 (subsequent designation: Pilsbry 1916 : 260). Recent: Chile below 30°S, Cape Horn to Punta Arenas, Argentina , Falkland Islands . Elminius kingii is remarkably tolerant of high levels of fresh water, occurring with essentially freshwater amphipods ( Hyallela ) at the mouth of the Rio Salton in southern Chile ( Davenport et al., 1995 ). Remarks: Elminius is now a monotypic genus. Further important characters of E. kingii are the broad, smooth edged radii and the large orifice.
