First record of Cymatodiscus planetophorus (Bacillariophyta) for littorals of NW Mexico; ecological remarks
ABSTRACT As part of a floristic analysis of diatoms (Bacillariophyta) at Reserva de la Biosfera Marismas Nacionales in Nayarit, Mexico, Cymatodiscus planetophorus is recorded for the first time in the northwestern coasts of Mexico. Samples were collected from various substrata in estuarine wetlands in areas of production and fishing of pleasure oyster Crassostrea corteziensis and mullet Mugil curema, respectively. Specimens of C. planetophorus were successfully distinguished of Cymatotheca weissflogii based on meristic and morphological characteristics using optic microscopy. Their frequency and abundance on the inspected substrata confirm the benthic/tychoplanktic habit of this taxon. Both M. curema and C. corteziensis are added to the list of consumers of C. planetophorus; the latter also as a new substrate. Complementary ecological remarks are provided.
