C6855D2C97325CFB966212880C942FD4.taxon	description	Description. In LM (Fig. 1 A – G), valves small, elliptic to linear elliptic, with pronounced sternum and broadly rounded apices, 7.6 – 9.0 μm in length and 3.4 – 4.8 μm in width (n = 20). Raphe narrow, straight. Axial area lanceolate, broad towards valve center, fusing with transverse expanded central area. Central area wide, irregular, bordered on each margin by 7 – 10 shortened striae. The striae radiate throughout, 32 – 40 in 10 μm. In SEM (Fig. 2), internally, raphe linear with thick distinct sternum (Fig. 2 A). Central raphe endings slightly deflected to the same side of the valve (Fig. 2 B). Distal raphe fissures terminated in small helictoglossae (Fig. 2 C). Areolae small and round. Striae composed of 2 – 9 areolae. Central area wide. Externally, proximal raphe ends expanded and pore-like, surround by a shallow grove and slightly deflected in one direction (Fig. 2 D, E). Terminal fissures bend markedly to the opposite direction of the proximal ends (Fig. 2 F). Areolae small, round, and occluded by hymens. Striae composed of 6 – 8 round areolae and extended slightly onto the shallow margin of the valve.	en	Du, Fei-Chao, Wei, Na, Li, Hao-Yu, Xu, Zhen-Quan, Li, Yu-Hang, Zhang, Man (2025): Morphology and molecular phylogeny of Mayamaea densestriata sp. nov.

C6855D2C97325CFB966212880C942FD4.taxon	etymology	Etymology. The specific epithet Mayamaea densestriata refers to the unusually high number of areolae per stria observed in this species. It highlights a key diagnostic feature that distinguishes it from its morphologically similar congeners.	en	Du, Fei-Chao, Wei, Na, Li, Hao-Yu, Xu, Zhen-Quan, Li, Yu-Hang, Zhang, Man (2025): Morphology and molecular phylogeny of Mayamaea densestriata sp. nov.

C6855D2C97325CFB966212880C942FD4.taxon	distribution	Distribution and ecology. Mayamaea densestriata is currently known only from its type locality. It is a terrestrial species associated with moist soil environments within cultivated agricultural landscapes.	en	Du, Fei-Chao, Wei, Na, Li, Hao-Yu, Xu, Zhen-Quan, Li, Yu-Hang, Zhang, Man (2025): Morphology and molecular phylogeny of Mayamaea densestriata sp. nov.
