Georgiev, Dilian & Glöer, Peter, 2020, Three new hydrobiid species from Thassos Island (Greece) with a re-description of Amnicola charpentieri Roth, 1855, Ecologica Montenegrina 35, pp. 129-137 : 133-134

Bythinella charpentieri Roth, 1855 ( Figs. 1 , 2 , 9-15 )

Type locality: Hymettos, east of Athens , Attika .

There are four samples (Kephesos, Attika, 2x Hymettos ) marked as Syntypes in ZSM . Only one sample contained a specimen which corresponds to the original description. Thus we designate this species as the lectotype ( ZSM 20012106) .

Re-description: The ovate-cylindrical shell has 4.5-5 regularly growing convex whorls with a deep suture. The aperture is ovate with a round angle at the top. The aperture height takes 1 / 3 of shell height. The peristome is sharp, somewhat reflexed at the columella. The umbilicus is closed. The shell is 3.3 mm high and 1.8 mm broad.
