Pl. 16, fig. F

Gray, 1850. Proceedings of the Zoological Society of London, 17 (1849): 165.

Type material: Syntypes (6), NHMUK 1849.12.3.46–48 & 1850.12.28.520–522 (combined lots, dry shell material) .

Label details: ‘ New Zealand, Major Greenwood’.

Type locality: ‘ Auckland, New Zealand’ (Gray 1850: 165) .

Remarks: Type material of this species has not been illustrated previously. The original description of Nanina erigone , which was reproduced by Gray (1851: 65), was based on material collected at Auckland c. 1847–1849 by Major Joseph Greenwood, and sent to the British Museum. Martens (1873: 11) noted that Nanina erigone was very similar to Helix heldiana Pfeiffer, 1853 , and they were treated as synonyms by Hutton (1884b: 197), Hedley & Suter (1893: 648), and Suter (1894d: 276; 1913b: 750).

Current Taxonomy: Listed as Phrixgnathus erigone (Gray, 1850) by Hutton (1884b: 197), Suter (1904a: 61), Spencer & Willan (1995: 41) and Spencer et al. (2009: 217).

Distribution: New Zealand; northern North Island ( Suter 1913b; Powell 1979).
