Summary:Philobrya wandelensis Lamy, 1906 (Figure 18) Philobrya wandelensis Lamy, 1906a: 50, 51, fig. 4; Melvill and Standen 1907: 116; Dell 1990: 29, figs. 42, 47–49; Absher and Feijó 1998: 440, fig. 3F; Narchi et al . 2002: 655, 656, figs. 14 and 43; Aldea & Troncoso 2008: 94, 95, 103, fig. 92; Jackson et al . 2015: fig. 2l; Urcola & Zelaya 2021: 25, 26, fig. 2. Hochstetteria wandelensis. Carcelles 1953: 214, pl. 5, fig. 102. Adacnarca wandelensis. Nicol 1966: 33, 34, pl. 3, figs. 4, 5; M̧hlenhardt-Siegel 1989: 160, pl. 2, fig. 16 and pl. 5, fig. 16; Hain 1990: 87, pl. 13, fig. 1a, b. Remarks: Philobrya wandelensis was recently redescribed by Urcola & Zelaya (2021). The species is characterized by its modioliform shell with a long anterior portion of the dorsal margin, a microscopically pitted prodissoconch and a cancellate dissoconch covered with a dark brown periostracum, forming strong radial folds. Philobrya wandelensis is most similar to P. sanjuani (Fig. 16; see comparison under that species). Other morphologically similar species to P. wandelensis are P. atlantica (Fig. 4), P. brattstromi (Fig. 8), and the small-sized (up to 4.2 mm L) specimens of P. blakeana (Fig. 6). Philobrya wandelensis clearly differs from all these species by having a pitted prodissoconch and shorter resilifer (Appendix 1). In addition, P. wandelensis differs from P. atlantica and P. brattstromi by having shorter periostracal setae and from P. blakeana by having a lower density of setae. Furthermore, P. wandelensis is distributed from Antarctica to the Scotia Arc islands, while P. atlantica , P. brattstromi , and P. blakeana appear around the southern tip of South America.
