Monacha samsunensis (Pfeiffer, 1868): another Anatolian species introduced to Western Europe, where it is known as Monacha atacis Gittenberger & de Winter, 1985 (Gastropoda: Eupulmonata: Hygromiidae)

Populations of Monacha atacis from southern Occitania in France and of M. samsunensis from northern Anatolia in Turkey (Atakum/Samsun and Kastamonu) were investigated by an integrative approach based on morphological (shell and genitalia) and molecular (mitochondrial and nuclear gene sequences) features. Morphological examination revealed a complex pattern of variation within and between geographically separated populations, while molecular analysis showed strong similarity between the two species, confirming earlier suggestions that the species are conspecific. Pfeiffer’s name Helix samsunensis introduced in 1868 has priority over the name M. atacis given by Gittenberger & de Winter in 1985. © 2022 The Author(s).

An anomaly of the reproductive organs in Trochulus hispidus (Linnaeus, 1758) (Gastropoda: Pulmonata: Hygromiidae)

A specimen of Trochulus hispidus from Buchenbach, Germany, had its male and female parts of thereproductive system completely separated. The female part lacked auxiliary organs. The male part opened into the genital atrium, but the vas deferens was blind-ended in a way precluding sperm transfer

On the spelling of Trochulus Lubomirskii vs. Lubomirski (Slosarski, 1881) (Gastropoda: pulmonata: hygromiidae) - the opposite point of view

The paper discusses arguments for the preservation of the original spelling of the species-level name for Trochulus lubomirski (Ślósarski, 1881) versus arguments for the preservation of the amended spelling lubomirskii. The authors argue that the obvious "prevailing usage" of the spelling lubomirskii should be taken as the decisive argument to preserve this form of spelling under Art. 33.3.1 of the International Code of Zoological Nomenclature
