APLYSIA ALLOCHROA BERGH, 1908

Aplysia allochroa Bergh, 1908: 4–5 , pl. 1, figs 4–10. Type locality: Knysna, South Africa. Type: Probably lost, not at NHMD (K. Jensen, pers. comm.)

Remarks

Bergh (1908) described Aplysia allochroa in great detail, including descriptions of two preserved specimens collected in Knysna, South Africa. Eales (1960) placed A. allochroa in the synonymy of A. parvula , but anatomical descriptions by Bergh (1908) are not consistent with this assessment. First of all, the shell of A. allochroa is much broader than the shells of A. parvula s.l. described herein. Additionally, the penis of A. allochroa has a single retractor muscle, different from all other species of A. parvula s.l., which have two. Thus, we are confident A. allochroa is not one of the species of A. parvula s.l., but we are unsure of its identity.
