Description: Shell as described by Climo (1970).

Reproductive anatomy: As described and illustrated by Goulstone and Mayhill (1998) and in Figure 6.

Remarks: The genus Climocella was introduced by Goulstone in 1996. Goulstone and Mayhill (1998: 282) mentioned that Charopa (Mocella) accelerata Climo, 1970 was previously assigned to Climocella , but Goulstone (1996) never introduced that particular name combination (cf.MolluscaBase). Goulstone and Mayhill (1998: 273) transferred Charopa (Mocella) accelerata Climo, 1970 to Flammocharopa Climo, 1970 . We agree with Goulstone and Mayhill (1998: 284) that the species does not belong in Climocella . Anatomically S. accelerata is close to NZ Sinployea and Calymna species ( Figs 4–6) but shares the sparse protoconch lirae with Sinployea . Shells of Calymna species have an embryonic sculpture of spiral corrugations. Figure 17 depicts the similar protoconch sculptures of sparse lirae of S. accelerata and Climocella prestoni , but axials never appear on the protoconch of Sinployea species as observed in Climocella .

Kerry Walton, Te Papa, suggested that a specimen registered as NMNZ M.046683 could be the lost holotype of S. accelerata , which would invalidate the neotype selection, NMNZ M.137192, Goulstone and Mayhill (1998: 284). However, there is not enough information in the original publication to ascertain whether the specimen from near Turakina ( NMNZ M.046683), which is not marked as type material, is indeed the missing holotype, because the original publication does not provide an illustration .

Distribution: New Zealand, North Island (except furthest north).

Ecology: Sinployea accelerata is found in mature forests or remnants, usually associated with bark crevices under fallen rotting logs (Goustone and Mayhill 1998: 284).

Conservation status: We recommend listing this species as ‘Not Threatened’. Additional Northland localities not shown by Goulstone and Mayhill (1998: 284, fig. 6) are mapped in Figure 16.

Northern NZ loosely coiled Sinployea species Thisgroupincludes Sinployeasolemi, Sinployeahaupatoto, Sinployea ohinepoutea , Sinployea mangamuka , Sinployea waipoua , Sinployea kaipara , Sinployea karangahake , Sinployea imperforata , Sinployea hikurangi , S. capensis , and S. accelerata ( Figs 16, 43, 44). Sinployea solemi and S. karangahake from northernmost and eastern Northland locations are species with flammulated to zigzag colour patterns and more coarsely ribbed shells. Both species adjoin the distributions of species with chiefly brown shell colour patterns and fine teleoconch ribbing, S. haupatoto , S. waipoua , S. kaipara , and southern NZ S. fiordlandica . Sinployea imperforata and S. ohinepoutea are intermediate with regard to geography and morphology. Sinployea species with unicoloured shells occur from Whangarei to Wellington, North Island and southeast of Nelson and Invercargill, South Island. The North and South Island localities would have been geographically closer pre-Alpine Fault displacement, as is discussed in the biogeography section ( Fig. 45). The species with unicoloured shells form a central core, with the colour-patterned species distributed around the periphery. They include S. accelerata , S. hikurangi , S. capensis , S. maitai , and S. australis .
