The aquatic snails of the genus Moquin-Tandona, 1856 are common in springs and spring-fed brooks throughout Greece and include a number of endemics. To date, 23 species of the genus Bythinella have been known from Greece (Glöer & Hirschfelder 2019; Glöer & Hirschfelder 2020; Glöer & Reuselaars 2020a,b,c; Georgiev & Glöer 2020; Glöer & Pešić 2020). Bythinella charpentieri (Roth, 1855) has been listed by many authors from different sampling sites in Greece. Boettger (1885: 198) reported latter species from Laconia, Elis, Achaia in Morea, Phthiotis and on Euboea as a “common species”. Later on, Schütt (1980: 129) gave a description of B. charpentieri. He believed that all Bythinella spp. of Greece belong to B. charpentieri, except B. kosensis Schütt, 1980 and B. cretensis Schütt, 1980, and many authors followed him. Recently, Georgiev & Glöer (2020) studied the syntypes of Roth’s collection in the Bavarian State collection of Zoology Munich and designated the lectotype of Bythinella charpentieri based on the material from Hymettos (Attika). Falniowski & Szarowska (2011) collected B. charpentieri at the type locality (locality no. 12 in their paper), but they did not give a photo of either the shell or the penis. However they barcoded specimens of the latter species obtaining sequences in both the COI and ITS-1. During a hydrobiological survey the junior author (Anastasios Porfyris) visited the type locality and collected living specimens of B. charpentieri. The aim of this paper is to provide for the first time a description of the penis morphology (Fig. 1) which will enable reliable identification of this species.

Material examined: 15 specimens from the type locality: spring near the old Monastery in Kaissariani, Hymettos Mt., Attica, Greece. Description: The penis and the penial appendix are broader than usual in Bythinella. The tubular gland is proximally very thin but regularly thick from the second third part to the distal end of the gland. Distribution: Greece; nly known from the type locality.

Habitat: The species lives in water coming from a spring (Fig. 2) just outside of the old Monastery in Kaissariani, at the foothils of Hymettos, Attica, Greece. The spot is quite small and the water is unsuitable for drinking. It also has a sulfur-like odour, which can discourage human interventions of any type. We suggest that no cleaning action should be done there (wiping the stone or collecting the rotten leaves), because this can badly affect the species population.
