Recharacterization of Synapterpes (S.) hanleyi (Pfeiffer) (Mollusca, Gastropoda, Stylommatophora, Subulinidae)

Abstract

ABSTRACT. Synap/erpes (S) hallleyi (PfeifleI', 1846) is characterized by anatomy, synonymy and geographical distribution. Shell and soft pal1s were studied and importanttaxonomic characters evaluated and illustrated. These studies give conditions to characterize the species and include it in the genus Synaplelpes Pilsbly, 1896 and distinguish S hallleyi from the other species of SYllaplerpes S.S. known only by their shells, respectively from Brazil and Colombia: S.(S) corona/us (Pfeiffer, 1846) and S. (S.) wallisi (Mousson, 1869).

“…The absence of a bursa could be explained by the intense coiling of the shell, with scarcity of inner space. However, other highly coiled taxa, such as subulinids, possess well-developed bursas (e.g., Dutra, 1988;Salgado & Coelho, 1999). Besides, the insertion of the vas deferens has been referred to insert remote from the distally inserting penal retractor muscle (Sutcharit et al, 2010: 9); however, as shown in Fig.…”
