	1	+The new species differs from all the remaining species of the subgenus //Sinalbinula //in having ovate−conical but always slender shell, a weak crest on the body whorl (with tendency to reduce) and generally weak apertural barriers. Specimens with somewhat larger apertural barriers show some similarity to //G. nouletiana// (Dupuy, 1850), but the elongate shell shape, smaller size, less convex whorls and distinctly weaker crest on the body whorl in //G. sandbergeri //easily separate the two species. The new species differs from the group of very slender species, such as //G. didymodus// (Sandberger, 1858), G. fissidens (Sandberger, 1858), and //G. obstructa// (Sandberger, 1874), in that the parietal and angular portion of parietoangular tooth are partly fused (three latter species have a cylindrical shells with angular more or less distinctly separated from parietal). Compared to //G. pseudotheeli// Steklov, 1966 the new species has somewhat similar parietoangular tooth but the former species is distinguished immediately in having a solid crest on the body whorl.

	1	+// Gastrocopta sandbergeri //differs from //G. nouletiana// (Dupuy, 1850)—even from small specimens and also those previously regarded as a slimmer form gracilidens—in the following characters: (1) more slender shell (H/W ratio in 20 nouletiana specimens = 1.55–1.88, mean 1.73; in 20 sandbergeri specimens = 1.80–2.16, mean 1.95); (2) distinctly weaker crest on the body whorl; (3) apertural barriers generally weaker developed. In some specimens of //G. nouletiana// from various localities the parietoangular tooth may be rather weakly developed, as in //G. sandbergeri//, but the shell shape and size easily separate the two species (Fig. 2F). The new species can not also be confused with //Gastrocopta serotina// Ložek, 1964 (Fig. 2G) as the latter species is most similar to// G. nouletiana.//
