BUSTOS, Sabrina; MORALES, Marcelo R  e  MAIDANA, Nora I. Diversidad del género Luticola (Bacillariophyceae) en sedimentos holocenicos de la Puna Jujeña, Argentina. Bol. Soc. Argent. Bot. [online]. 2017, vol.52, n.1, pp.13-26. ISSN 1851-2372.

Framed in our paleoenvironmental research project, we have observed a high diversity and frequency of diatoms of the genus Luticola D.G. Mann in sediments of the last 11,000 years of Barrancas locality (S 23° 18’ 08,7”; W 66° 05’ 15,2”; 3666 m asl). We identified ten taxa, two of them are new species -Luticula punae and L. juliae-, and we described 2 different forms of L. mollis. Two of these species are new records for Argentina and one for South America.
