Abstract
BLANCO, Saúl et al. Taxonomy and morphology of Cratícula gadorensis sp. nov. (Bacillariophyta, Stauroneidaceae). Bol. Soc. Argent. Bot. [online]. 2019, vol.54, n.1, pp.1-5. ISSN 1851-2372.
Background and Aims: The diatom Craticula gadorensis sp. nov. is described from samples of epilithic algae collected in a shallow pond from the Gador mountains, in the province of Almería (Spain). M: Samples were taken and processed following the usual protocols for diatoms. Morphological and ultrastructural characteristics of this new taxon are described and illustrated using light and scanning electron microscopy. Results: The new species is characterised by having elliptic-lanceolate to rhombic-lanceolate valves, with slightly protracted, subrostrate apices, a linear, narrow axial area and a slightly dilated, linear-lanceolate central area. Conclusions: A morphological comparison with related species shows that the combination of features in Craticula gadorensis is unique (mainly the dimensions, areola density and the shape of the central area).
