Abstract

Observations of asample from a small spring on MountainOsogovo revealed the presence of several interesting and previously unknown small-celled diatom species. Among them, the genus Mayamaeashows relatively high diversi-ty, with at least eight species. Four species are presented in this study, two of which are described as new: Mayamaea matevskianasp. nov. and Mayamaea stafiloviiLevkov & Zaova sp. nov. Mayamaea matevskianais characterized by elliptical to elliptic-lanceolate valves, relatively coarse and strongly radiate striae, an indistinct central area bordered by more distantly positioned central striae, slightly expanded proximal raphe ends, and simple distal raphe ends. Maya-maea stafiloviihas a similar valve morphology and shape of the central area to M. matevskianabut differences can be observed in the valve size (which is considerably smaller than M. matevskiana) and the shape of the external distal ra-phe ends (which are long, slightly deflected, and extend onto the valve mantle). The new species are described based on detailed light and scanning electron microscopic observations.
