Abstract
Sarasinula plebeia is a common land slug in tropical and subtropical areas, including South America. This species is known as Bean-slug but considered a pest of great importance in numerous crops, horticultural facilities, plant nurseries, and garden. Also, it is a natural host for nematodes that cause parasitosis in different countries. We report for the first time the occurrence of Sarasinula plebeia in Argentina, based on material collected in the provinces of Chaco and Misiones, extending the distribution of the species in South America to 34 terrestrial ecoregions.

In the reviews carried out by Thomé (1989, 1993), who studied the group for decades, he considered four possible valid species: S. linguaeformis (Semper, 1885), S. marginata (Semper, 1885), S. dubia (Semper, 1885) and S. plebeia (Fisher, 1868)
Summary
Several species of the genus Sarasinula have been nominated for South America. in the reviews carried out by Thomé (1989, 1993), who studied the group for decades, he considered four possible valid species: S. linguaeformis (Semper, 1885), S. marginata (Semper, 1885), S. dubia (Semper, 1885) and S. plebeia (Fisher, 1868). Thomé (1989) questioned the validity of S. dubia and S. marginata, which he considered a possible synonym of S. plebeia and S. linguaeformis, respectively. In the reviews carried out by Thomé (1989, 1993), who studied the group for decades, he considered four possible valid species: S. linguaeformis (Semper, 1885), S. marginata (Semper, 1885), S. dubia (Semper, 1885) and S. plebeia (Fisher, 1868). Thomé (1989) questioned the validity of S. dubia and S. marginata, which he considered a possible synonym of S. plebeia and S. linguaeformis, respectively. In S. plebeia the penis is club-shaped, while in S. dubia it is tapered in the distal extremity (Thomé, 1989), which, can be considered a morphological variation in S. plebeia (Gomes & Thomé, 2001, 2002). Further research by other authors already considered these species synonyms (Mansur & Thomé, 1994; Rueda et al, 2002; Naranjo-García et al, 2007; Molet, 2014; Oliveira Rocha, 2019)
