Amphidromus maculiferus obscura Fulton, 1896

Amphidromus maculiferus var. obscura Fulton, 1896a: 75.

Type locality.

Mindanao Island.

Type material.

Lectotype (design. n.), NHMUK 19601535/1 (Fig. 12A; H=61.4 mm, W=31.5 mm), paralectotypes NHMUK 19601535/2-3 (1D + 1S, Fig. 12B).

Remarks.

The original description was based on more than one specimen, since Fulton stated “… remarkable that this is the only form of maculiferus of which dextral specimens have been found …”. A unique type was not indicated in the original description. The NHM holds a lot that consists of three specimens (2D, 1S) from the H. Cuming collection with an original label in Fulton’s handwriting. The dextral specimen closely matches with the original description and is here designated as the lectotype to stabilise the name.
