Figure 3Q–S

Bulimus beckianus L. Pfeiffer 1846: 82 .

Material examined. Brazil • Acre, Porto Acre , HFR; 09°45′12″S, 067°40′09″W; 23.IX. 2018; M. Lima and W. Lima leg.; 5, UFAC 971 .

Identification. This is the first specific record of B. beck- ianum from Acre. Despite being within the species’ expected distribution (it is common in Latin America), the present record is actually an extension of the species’ known distribution within Brazil, given that its closest known record was previously from Pará state ( Birckolz et al. 2016).

Type locality. Opara Island, Polynesia ( Pfeiffer 1846). Pilsbry (1906) considered this locality mistaken, arguing that Pfeiffer’s specimens were most similar to those from Central America ( Salvador and Simone 2015; Silva et al. 2019).

Distribution. Mexico to Brazil (Pará to São Paulo, Fernando de Noronha), including the Caribbean Islands ( Simone 2006; Birckolz et al. 2016). It has been introduced to Hawaii and to greenhouses in Europe ( Cowie 1997; Horsák et al. 2020).
