Montana Diatom Collection (MDC) sample 179801; holotype slide MDC B1-22-5, Figs 1–4; isotype slide MDC B1-22-6.</p> <p>Valves lanceolate to elliptic-lanceolate with subrostrate, broadly rounded apices. Shallow pseudoseptum occupies each apex (Fig. 4). Valve length 47–55 µm; valve width 10.0– 12.3 µm. Raphe filiform, slightly sinuous, with a pronounced bend near the proximal ends, which are weakly inflated. Distal raphe ends hooked towards the same direction. Axial area c. 4 x wider than raphe, following the same contours, including the aforementioned bend. Central stauros broad, largely rectangular, scarcely wider at valve margins.

It differs from S. obtusa Lagerstedt (1873: 36) by having subtly protracted apices and somewhat wider valves relative to their length. Stauroneis microbtusa Reichardt (2004: 442) has more steeply radiate striae and a central stauros that is shaped like a bow tie. Stauroneis clarkii is known only from the type locality, which it shares with S. sacajaweae.</p> </div>	http://treatment.plazi.org/id/F67E504B116AF1284B8E76E0FB83FAAD	Public Domain	No known copyright restrictions apply.

Valves of S. spauldingiae are somewhat larger, and have a lower stria density and a smaller, more rectangular stauros than specimens designated by Reichardt (1995: 25) as the lectotype of S. anceps (Sippe 1, Tafel 16, Figs 1–12). The occurrence of S. anceps — one of the most frequently misidentified species of Stauroneis — remains to be confirmed in the USA. In addition to the type locality, S. spauldingiae has been collected from several small lakes and ponds in western Montana and northern Idaho (Bahls 2010). These waters have circumneutral pH and very low concentrations of dissolved solids.</p> </div>	http://treatment.plazi.org/id/F67E504B1168F12A4B8E74A2FBF0F920	Public Domain	No known copyright restrictions apply.
