Taxonomy
Arca kosoviensis was named by Barrande (1881) [Includes the following misidentifications according to Kříž and Steinová 2009: 420:
1934 Ctenodonta praecox (Barr.). – Pfab, p. 228, pl. 2, fig. 14.
1934 Ctenodonta disputabilis (Barr.). – Pfab, p. 228, pl. 2, fig. 15.
1934 Ctenodonta (Palaeoneilo) flectens (Barr.). – Pfab, p. 230, pl. 2, fig. 18.
1934 Ctenodonta (Palaeoneilo) magna (Barr.). – Pfab, p. 231, pl. 2, fig. 19.]. It is a 3D body fossil.
It was recombined as Praearca kosoviensis by Neumayr (1891) and McAlester (1968); it was recombined as Sluha kosoviensis by Newell (1969) and Kříž and Steinová (2009).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. Kříž and M. Steinová 2009 | Upper Ordovician longitudinally elongated Sluha with the anterior smaller and the posterior larger part; taxodont dentition developed anteriorly and posteriorly of umbo.
Shell medium size, equivalved, inequilateral, broadly ovate, and longitudinally elongated (H/L = 0.5–0.8). Anterior part of the shell is smaller. Anterior and posterior margins evenly rounded, ventral margin long and convex, postero-dorsal angle rounded, and dorsal margin slightly convex. Umbones prominent, in anterior half of the shell, beaks are prosogyrate. Umbonal ridge well defined, becoming obsolete before reaching post-inferior extremity. Outer surface sculpture consists of fine growth wrinkles. Inner surface is smooth. Ligament is probably external. Hinge line in anterior part of the shell slightly curved ventrally, in posterior part straight or slightly convex. Taxodont teeth are small, in the posterior part of the hinge line slightly larger, and with obliquely orthomorph shape (according to Babin 1966, p. 39). Muscle scars unknown. |
