Resumen

ALVES-DA-SILVA, Sandra Maria  y  BICUDO, Carlos Eduardo de Mattos. Strombomonas carinata sp. nov. and Strombomonas ferrazi sp. nov., two new Euglenophyceae from the state of Rio Grande do Sul, southern Brazil. Acta Bot. Bras. [online]. 2003, vol.17, n.1, pp.147-154. ISSN 0102-3306.  http://dx.doi.org/10.1590/S0102-33062003000100011.

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.

Palabras clave : Strombomonas carinata sp. nov.; Strombomonas ferrazi sp. nov.; Euglenophyceae; Rio Grande do Sul State; Brazil.
