Remarks.

There are 18 paratypes in ethanol mentioned in the original description under A6281/T3286. However, this number refers to 3 paratypes (T3286/ NMSA-MOL 0A6281), one of which was donated to Drivas (12 Oct. 1988), which are shells without soft parts, not in ethanol. There are 14 specimens in ethanol with the catalogue number NMSA-MOL 0D2170. Since these are the only other specimens of S. aphanes in ethanol, which in addition match the locality and collector as in the original description, they are assumed to be paratypes and were given new type number T4328 in preparation of this manuscript. There are another two shells in NMSA-MOL 0D489 paratype lot that were not chosen as paratypes. Prefix “C” was omitted in the original description for C5909. Figured paratypes were given wrong number (D2157/T3327 instead of D2156/T3295) in the original description ( Robson 1986: figs 4-11). One (of originally eight paratypes: T3295/ NMSA-MOL 0D2156) was sent in 1990 to Zoological Museum of Moscow University.
