Helix stipulata Reeve, 1852

Pl. 6, fig. H

Reeve, (1851–1854) 1852. Conchologia iconica, 7: species 813, pl. 132, fig. 813.

Type material: Lectotype, NHMUK 1985026 , paralectotype (1), NHMUK 1985027 (dry shell material); ex. Mus. Cuming (Acc. no. 1829) . Lectotype designated by Climo (1980: 295).

Label details: ‘ H. alpha Pfr. ’ in Pfeiffer’s handwriting. ‘N. Zealand’.

Type locality: ‘New Zealand’ (Reeve 1852 [in 1851–1854]: species 813).

Previous illustrations of type material: Reeve (1852 [in 1851–1854]: pl. 132, fig. 813), Climo (1980: fig. 1C, D).

Remarks: Helix stipulata Reeve, 1852 and H. alpha Pfeiffer, 1853 are based on the same type material, which Cuming had obtained from the Australian-based naturalist Frederick Strange. Pfeiffer evidently intended to publish the original description of this species in the Proceedings of the Zoological Society of London issue for 1851 (see Reeve 1852 [in 1851–1854]: species 813; Pfeiffer, 1853a: 112), but publication was delayed until 1854 ( Pfeiffer 1854a: 58), and was pre-empted by Reeve (1852 [in 1851–1854]). Helix stipulata Reeve, 1852 is the type species of Thera Hutton, 1883 (non Stephens, 1831) by original designation. Pilsbry (1892a: 55) designated H. alpha Pfeiffer, 1853 as the type species of Aeschrodomus Pilsbry, 1892 , which was a replacement name for Thera Hutton, 1883 , but Hutton’s (1883c: 532) designation of the type species of Thera takes precedence by typification of the replaced name (ICZN Article 67.8).

Current Taxonomy: Listed as Aeschodomus stipulatus (Reeve, 1852) by Iredale (1915: 481), Climo (1980: 294) and Spencer et al. (2009: 215).

Distribution: New Zealand; southern South Island ( Climo 1980).
