Type locality.

near Matanzas, Cuba.

Material studied.

Karratha area: 20.7385°S, 116.8357°E (WAM S9932, WAM S60237).

Distribution.

This species has previously been recorded from just north of Broome (Quondong Point) across northern Australia to mid-eastern Queensland and offshore islands ( Solem 1989, Shea 2006). In addition, it is now recorded from a single locality within the Karratha town site (Figure 4).

Comparative morphology.

The shells of Gastrocopta servilis are easily distinguished from other Pilbara Gastrocopta by their (1) strongly rounded whorls (2) short, straight columellar tooth which is perpendicular to the mid-columellar wall (3) very long angular tooth which is fused with the parietoangular tooth (4) weak to absent basal tooth and (5) weak to absent upper palatal tooth.

Remarks.

Gastrocopta servilis has been a recent introduction to the residential gardens of Karratha.
