Tintinnids (Ciliophora - Suborder Tintinnina) from subantarctic and antarctic waters between Argentine and Antarctic Peninsula (35º8-62º8) (November/1992)

Abstract

A taxonomic survey on the tintinnids (Suborder Tintinnina) sampled from surface waters along a latitudinal transect between Argentine and Antarctic Peninsula (35ºS-62ºS) was made in November 1992. Twenty two taxa were determined, belonging to the genera Acanthostomella, Amphorides, Codonellopsis, Coxliella, Cymatocylis, Favella, Helicostomella, Laackmaniella, Protorhabdonella, Stylicauda and Tintinnopsis. The species Acanthostomella norvegica, Amphorides quadri/ineata, Codonellopsis gaussii, Cymatocylis antarctica, C. convalaria and Tintinnopsis baci/laria were abundant in the samples. The species C. antarctica dominated in most of the stations sampled in subantarctic waters, while C. convalaria and Codonellopsis gaussi were abundant in antarctic waters. The genera Favella, Helicostomella, Stylicauda and the species Tintinnopsis gracilis were only recorded in waters under the intluence of the La Plata river. For ali species, we provided descriptions, measurements and drawings, as well as comments on the taxonomy.
