Valves linear-lanceolate with concave-contracted margins at the mid-valve and protracted, rostrate ends (Fig. 1 A – J). Valve dimensions (n = 25): Length 32.0–35.7 µm; width 3.9–6.3 µm. Striae visible, 18–19 in 10 µm, weakly radiate.</p><p>SEM (Fig. 3). Axial area narrow and linear, central area circular (Fig. 3 G, H). Raphe straight, filiform. Externally, proximal raphe endings expanded into central pores and slightly deflected to the same side (Fig. 3 A, G); internally, almost straight (Fig. 3 B, H). Distal raphe endings externally hooked, reaching the valve mantle at the apex (Fig. 3 E). Internally, helictoglossae developed and distal ends slightly bent on the same side (Fig. 3 F). Striae slightly curved around the central area and convergent at the ends; uniseriate (Fig. 3 A, B). Internally, areolae circular at the valve center (37–46 in 10 µm; Fig. 3 H); becoming elongated and elliptical toward the ends (18 in 10 µm; Fig. 3 F); but linear in external view (21 in 10 µm; Fig. 3 E). In girdle view, areolae continuing onto the mantle (40 in 10 µm; Fig. 3 C). “ Craticula ” or “ heribaudii ” stages not seen. Teratological forms were frequently observed (26 % of the population, n = 96 out of total valves), including abnormal valve outlines characterized by deflected ends, absence of typical median constriction on one side, deformed copulae, and raphe modifications such as misalignment (Figs 2 A – I, 3 D).</p><p>Etymology.</p><p>The specific epithet scientiacivica refers to its discovery during the development of a citizen science project involving secondary schools.</p><p>Ecology and distribution.</p><p>Craticula scientiacivica was found under controlled experimental conditions in microcosms inoculated with material obtained from root scrapings of Myriophyllum alterniflorum . Although the species occurred across different microcosms, the highest population abundance was recorded in the control treatment. Environmental conditions were characterized by a pH of 9, a hardness of 1.3 ° dH, an ammonium of 0.1 mg L - 1, and a phosphate of 3 mg L - 1; nitrite and nitrate concentrations remained below the detection limit (&lt;LOD). During light microscopy (LM) observations, C. scientiacivica was found to be associated with Achnanthidium minutissimum (Kützing) Czarnecki, Craticula buderi (Hustedt) Lange-Bertalot, Encyonopsis microcephala (Grunow) Krammer, Navicula radiosa Kützing, Nitzschia amphibia Grunow, N. paleacea (Grunow) Grunow, N. tenuirostris Manguin, Gomphonema acuminatum Ehrenberg, G. capitatum Ehrenberg, G. subclavatum (Grunow) Grunow, Punctastriata lancetulla (Schumann) P.
