Philippines morph

Figs 2 (as Phil), 4E–G

Material examined

Two sequenced specimens (Table 1).

Remarks

Both sequenced specimens cluster together (Fig. 2), two haplotypes identified (Fig. 3).

Shell slender (largest specimen with SL 40.3 mm), coloured in different shades of brown, with lighter olivoid band and slightly convex upper anterior band having nearly median obtuse ridge (Fig. 4). In shell shape and colouration this form matches the subspecies A. hilgendorfi vezzaroi Cossignani, 2015, described from Aliguay Island, Philippines. This same morph is illustrated by Poppe (2008) as Amalda vernedei herlaari van Pel, 1989 (part: pl. 546 fig. 7) from Balut Island in 100–150 m; this illustrated shell attains 67 mm, which is significantly larger than ours. Depth range of sequenced specimens 437– 740 m.
