| Two species of Strombomonas (Euglenaceae, Euglenophyceae), S. carinata and S. ferrazi, are described and proposed as new to science. Sample units from which specimens were studied were collected from a reservoir (reservoir n. 7) located in an Environment Protection Park ("Parque de Proteção Ambiental") in the South Petrochemical Station ("Pólo Petroquímico do Sul") (29° 53'S, 51° 22'W), in Triunfo, state of Rio Grande do Sul, southern Brazil. Physical and chemical data of the water of the system from which the two species were collected are presented. |
