‘ Aclis ’ gittenbergeri ( de Jong & Coomans, 1988)

Figs 24D–E

Bermudaclis gittenbergeri de Jong & Coomans, 1988: 59 , pl. 4, fig. 303.

Type material. Holotype: ZMA.MOLL.138263. Paratype: Aruba; West coast of Aruba; ZMA.MOLL.138275 [1].

Type locality. Aruba: West coast of Aruba.

Remarks. This species was originally described in Bermudaclis Bartsch, 1947 , which is a junior synonym of Murchisonella Mörch, 1875 ( Peñas & Rolán 2013). Peñas & Rolán (2013: 61) noted that this species is not a Murchisonellidae , but possibly belongs to Aclis . However, the presence of low axial ribs and fine spiral striae in the whole teleoconch surface ( Fig. 24D, E ) does not fit in Aclis . The protoconch of this species seems slightly deviated. The study of the type material under SEM would be necessary for better classification, but we here suggest that this species is a ‘lower heterobranch’.
