Further studies on some saline lakes of south-east Australia

Abstract

A series of closed saline lakes located between Beachport and Robe in South Australia are discussed in more detail than previously. The following taxa are reported for the first time: the polychaete Capitella capitata (Fabricius), the dipteran Culicoides, the turbellarian Mesostoma, and the copepod Acartia clausii Giesbrecht. New taxa that will be described by other workers wholly or partially from material collected in this region are as follows: a new species and genus of hydrozoan probably belonging to the order Limnomedusae, and three new copepod species belonging to the genera Mesochra, Robertsonia, and Heterolaophonte. Previously recorded taxa which have now been more closely identified are as follows: "Nereidae" (earlier paper) → Ceratoneereis erythraeensis Fauvel (present paper), "Onychocamptus sp." → O. bengalensis (Sewell), and "Halicyclops sp. nov." → H. Ambiguus Kiefer. The cladoceran Daphniopsis pusilla Serventy is recorded from a salinity of 57‰. The significance of resistant stages, and the biological status of closed saline lakes located close to the sea, are discussed.
