Abstract

A single species of Maricarmenia Peñas & Rolán, 2017 was known, M. accresta Peñas & Rolán, 2017 from Fiji. Herein M. reticulata spec. nov. is described from the Spratly Islands in the South China Sea, thus much expanding the known range of the genus. Thus far three species of Eurathea Laseron, 1959 were known. Herein two species described in other genera are added: Rissoina liletae G. T. Poppe, Tagaro & Stahlschmidt, 2015 and the extinct Pliocene Rissoa sikokuana Nomura, 1937. Also four new species of Eurathea are described: Eurathea borneensis, E. darwiniana, E. japonica, and E. philippinensis, confirming the range of the genus throughout the central part of the Indo-West Pacific. The taxa in the genus Eurathea have medium to high spired, issoiform shells with a clear subsutural sulcus and marked shoulder with nodules, whereas the whorls have a sculpture of axial ribs and spiral grooves.

Abstract

This paper presents the first report of the green cellar slug Limacus maculatus (Kaleniczenko, 1851) from the Netherlands. Suspicions were raised after pictures of several specimens were put on the online data platform Waarneming.nl in November 2020 under the name of L. flavus (Linnaeus, 1758), a similar species already known from the Netherlands. Further investigation of external and internal components revealed that the specimens indeed belong to L. maculatus. This article describes this first discovery of L. maculatus in the Netherlands and provides a thorough discussion of the anatomical characteristics.
