Remarks.

Bulimus lusorius L. Pfeiffer, 1855 was described from the “ Banks of Amazon, Brazils ” ( Pfeiffer 1855). The lectotype NHMUK 1975543 illustrated in Breure and Ablett (2014: fig. 17 A – C) and the specimen illustrated by Simone (2006: fig. 487) are morphologically similar to the syntype of Drymaeus surinamensis described by Vernhout (1914) ( RMNH. MOL. 335814) and with all specimens identified as this species from French Guiana where it is the commonest species of its genus s. l. Thus, we suggest that Drymaeus surinamensis Vernhout, 1914 is a junior synonym of Bulimus lusorius L. Pfeiffer, 1855 until further investigations, in particular molecular data, are carried out.

Described as a subgenus of Drymaeus , Mesembrinus has been elevated to genus rank by Salvador et al. (2023).

Specimen A of Simone (2006: fig. 453, NMW. 1955.158) as well as specimen RMNH. MOL. 266069, both identified as Drymaeus germaini (Ancey, 1892) , might also belong to the species.
