39758780FFBFFF9F6FC1CB08FBDDC376.taxon	etymology	Etymology: — The specific epithet refers to the research project acronym AcquaSed: “ Base line diagnosis and reconstruction of anthropogenic impacts in the Guarapiranga Reservoir, focusing on the sustainability in water supply and water quality management in reservoirs of the Alto Tietê and surrounding basins ”, in which this study is included. Additional morphological data: — External raphe fissures are slightly undulate (Fig. 24), slightly closer to the ventral margin, while the internal slits are straight (Fig. 27). Proximal ends of raphe are almost straight, the enlarged proximal endings slightly curved to the dorsal side (Figs 24, 26). Distal raphe ends are comma-shaped, first dorsally bent, and then strongly hooked to the ventral side ending onto the mantle (Figs 24, 25). Axial area is narrow, linear (Fig. 24). Central area absent. Striae uniseriate, slightly radiate composed of apically-elongated lineolate areolae, some rounded areolae at the end of the stria (Figs 24 – 26) sometimes “ Y ” disposed (Fig. 26) numbering 40 in 10 μm. Transapically shortened striae composed of one lineolate and another rounded areolae continuing around the apex (Figs 24 – 25). Internal striae are lineolate and positioned between thickened internal costae (Figs 27 – 31) numbering 9 – 10 in 10 μm. Internally, there is a fissure located at the proximal end of the median dorsal stria (Figs 27 – 29) but externally, isolated puncti were not observed (Figs 24, 26). Separation of internal proximal raphe ends hooked strongly towards the dorsal margin, forming a very narrow intermissio (Figs 27 – 29) and the distal endings terminate in well-developed helictoglossae that are deflected towards the ventral margin (Figs 27, 30 – 31).	en	Marquardt, Gisele C., Da Rocha, Angélica C.

39758780FFB9FF9F6FC1CEA8FC65C6E2.taxon	etymology	Etymology: — The Latin name salesopolensis refers to the municipality of Salesópolis where samples were collected. Additional morphological data: — External raphe fissure are slightly undulate (Fig. 32), located approximately in the mid region of the valve. Proximal end of raphe almost straight, the enlarged proximal endings slightly curved to the dorsal side (Figs 32 – 33). Distal raphe ends are comma-shaped, first dorsally bent, then strongly hooked to the ventral side ending onto the mantle (Figs 32, 35 – 36). Axial area is linear-lanceolate (Fig. 32) to form a lanceolate central area, formed by very slightly shortened striae on ventral side and on dorsal side. Striae uniseriate, composed of apically-elongated areolae, sometimes “ Y ” disposed (Figs 32 – 34, 36 – 38) numbering 33 in 10 μm, radiate near the valve center, becoming parallel, then convergent near the apices. Transapically-elongated areolae, different shape and size, in shortened striae continuing around the apex (Figs 32, 34, 37 – 38), numbering 13 – 14 in 10 μm. Internally, struts provide structural support to the foramen, whose opening bears one very short spine at each side (Figs 35 – 36). Internal proximal raphe ends are widely separated and strongly hooked towards the dorsal margin (Fig. 36), and the distal endings terminate in well-developed helictoglossae that are deflected towards the ventral margin (Fig. 35). No isolated punctum is present.	en	Marquardt, Gisele C., Da Rocha, Angélica C. R., Wetzel, Carlos E., Ector, Luc, Bicudo, Carlos E. De M.

39758780FFB9FF9F6FC1CEA8FC65C6E2.taxon	biology_ecology	Ecology: — Encyonema acquasedis sp. nov. and Kurtkrammeria salesopolensis sp. nov. occur in acidic environments (pH 5.2 – 5.6), with water temperature around 17.6 – 25.5 ° C and electric conductivity 10.4 – 12.4 μS cm- 1 (Table 1). The new species were rare in samples collected from the plankton and surface sediments (relative abundance ≤ 2 %). In the planktonic samples both taxa were associated with species of Kobayasiella [i. e. K. micropunctata (H. Germain 1981: 234) Lange-Bertalot (1999: 267) and K. venezuelensis Metzeltin & Lange-Bertalot (2007: 155)], Eunotia [Eunotia sp., E. botuliformis F. Wild, Nörpel & Lange-Bertalot in Lange-Bertalot (1993: 29) and E. veneris (Kützing 1844: 40) De Toni (1892: 794)], Frustulia [F. crassinervia (Brébisson in Smith 1853: 47) Lange-Bertalot & Krammer in Lange-Bertalot & Metzeltin (1996: 57)] and Brachysira [B. brebissonii R. Ross in Hartley (1986: 607) and B. serians (Brébisson 1838: 18) Round & D. G. Mann (1981: 227)]. On benthic samples they were, associated with Brachysira brebissonii, B. serians, Eunotia botuliformis, E. bilunaris (Ehrenberg 1832: 87) Schaarschmidt (1881: 159), E. incisa W. Gregory (1854: 96), Eunotia sp., Frustulia crassinervia and Frustulia sp.	en	Marquardt, Gisele C., Da Rocha, Angélica C. R., Wetzel, Carlos E., Ector, Luc, Bicudo, Carlos E. De M.
