Abstract

The diatom flora of Unare and Píritu Lagoons, Venezuela, comprises freshwater, estuarine and marine organisms. In this paper, 15 species of diatoms belonging to the subclass Bacillariophyceae D.G. Mann are described. Water samples from Unare and Píritu lagoons (Venezuela) were collected from November 1988 to July 1989. Samples were fixed with neutral formaldehyde (10%) and were examined under phase contrast microscopy. Species under study were Dictyoneis marginata (Lewis) Cleve, Cymbella affinis (Kützing) Cleve, Cymbella sp., Achnanthes brevipes var. intermedia (Kützing) Cleve, Lyrella irroratoides (Hustedt) Mann, Navicula carinifera (Grunow) Peragallo, Navicula liber (W. Smith) Peragallo, Navicula vacillans (Schmidt) Peragallo, Navicula sp, Amphora crassa var. campechiana Grunow, Amphora decussata Grunow, Caloneis powelli (Lewis) Cholnoky, Tryblionella acuta (Cleve) Mann in Round et al., Tryblionella apiculata Gregory, Surirella febigerii Lewis.
