DEF7AFCB4B1255FC84622EB42B7DD27B.taxon	etymology	Etymology. The epithet Eunotia globicephala refers to the genus of the long-finned pilot whale [Globicephala melas (Traill, 1809)] as the apices of Eunotia globicephala bear a strong resemblance to the head and rostrum of this whale when seen in profile.	en	Taylor, Jonathan C., Cocquyt, Christine, Walsh, Gina (2024): Tropical African diatoms from the Eunotia asterionelloides (Bacillariophyta) species complex, with descriptions of new species.

The herbarium sheets sampled for diatom investigation (CCA 4510, 4511, 4521) on which Eunotia magnaparva sp. nov. was observed all came from the region around Eala, in the Province of Equateur, D. R. Congo. So far, this taxon was not observed in other materials from D. R. Congo.	en	Taylor, Jonathan C., Cocquyt, Christine, Walsh, Gina (2024): Tropical African diatoms from the Eunotia asterionelloides (Bacillariophyta) species complex, with descriptions of new species.

B74F4413F88C5F58AE10C433176F4D7D.taxon	etymology	Etymology. The epithet Eunotia magnaparva refers to the variability of this species in terms of size over the cell cycle, magna being large and parva small, reflecting that the cells range from particularly small to comparatively large.	en	Taylor, Jonathan C., Cocquyt, Christine, Walsh, Gina (2024): Tropical African diatoms from the Eunotia asterionelloides (Bacillariophyta) species complex, with descriptions of new species.

642DBDECCEA3510A9CD0B97AC1CD7970.taxon	description	LM description. Valves linear, arcuate with parallel margins. Ventral margins concave, dorsal margins convex. Apices slightly protracted and slightly expanded, rounded to bluntly rounded to slightly rectangular. Helictoglossae on the terminal nodules visible under LM as a small dot on the ventral margin. In girdle view, cells thin, isopolar, constricted in the middle portion. Striae parallel and equidistant, becoming radial towards the apices and always visible in LM. Valves measured in the present study (n = 18) with the following dimensions: length 19.5 - 31.0 µm, width 2.0 - 3.0 µm in the centre of the valve, and 2.5 - 3.0 µm at the apices. Stria density 20 - 22 striae per 10 µm in the centre of the valve. Valves measured from the type population (Wetzel et al. 2010) had the following dimensions: length 9 - 30.5 µm, width 2.5 - 3.5 µm in the centre of the valve, and 3.0 - 3.5 µm at the apices. Stria density 23 - 27 striae per 10 µm in the centre of the valve. Observed cells with characteristics consistent in general with the type population with the exception of the stria densities. Costa et al. (2017), however, documented a population from Brazil with lower stria density and consistent with the striae counts obtained in the present study (Table 1).	en	Taylor, Jonathan C., Cocquyt, Christine, Walsh, Gina (2024): Tropical African diatoms from the Eunotia asterionelloides (Bacillariophyta) species complex, with descriptions of new species.

Externally and internally, areolae composed of small round pores (Fig. 7 A), extending across the valve face and onto the mantle (Fig. 7 B). Valve face bordered by small spines, especially at the apices (Fig. 7 C).
