Sinployea ohinepoutea
Sinployea ohinepoutea was named in 2025 by Frank Climo, Karin Mahlfeld and David Roscoe, in their revision of the genus Sinployea. It belongs to the Charopidae: mostly tiny, finely ribbed snails of forest litter, and the largest family of New Zealand land snails.
| Family | Charopidae |
| Authority | Climo, Mahlfeld & Roscoe, 2025 |
| Threat status | Proposed in 2025, see Conservation below |
| Shell | Shell small, thin, and fragile, 1.95 mm wide and 0.93 mm high at approximately three whorls, moderately coarsely ribbed, loosely coiled, with a broadly flat spire. |
Distribution
New Zealand North Island: Northland, Puketi; East Coast: Ruatoria.
Habitat
Subtropical mixed broadleaf forest.
The name
Named after the farmstead near the type locality (~ 20 km W of Ruatoria, East Coast).
Conservation
Revision of collection material found a second specimen from Puketi Forest, S of Kaeo, eastern Northland. Puketi Forest is ~ 490 km from the only other known locality in East Coast. Twenty-nine collections from Puketi were checked, and 93 sampling records from elsewhere on topographic NZ Map 260 sheet P05, 19 samples from map sheet Y15, and 34 from Y16 and Y17. A total of 289 sampling records within an area of 6000 km 2 of map sheets of the East Coast, X14, X15, X16, X17, Y14, Y15, Y16, Y17, Z14, Z15, Z16, and Z17 (based on Te Papa collection), were also checked (Fig. 2). To our knowledge, the species has not been re-collected from the East Coast area since the mid-1980s and not from eastern Northland since the mid-1990s. On existing data, S. ohinepoutea has an eastern disjunctive range. Considering that there is little overlap in the distributions of Sinployea species, it is reasonable to assume that this species is probably also ‘At Risk: Naturally Uncommon’, with the qualifiers ‘Data Poor: Size and Trend’ and ‘Biological Sparse’. The 2010 NZTCS assessment ranked S. ohinepoutea as ‘Insufficient Information: Data Deficient’, with the qualifier ‘One Locality’.
