description: Amphidoxa costulata Hutton, 1882
Pl. 2, fig. E
Hutton, 1882. New Zealand Journal of Science, 1: 281.
Type material. Lectotype (designated by Climo 1970: 335), CMNZ M12778 [ex M294], and paralectotypes (2), CMNZ M294 (dry shells). The molluscan collection at CMNZ has radula fragments mounted on a glass slide with the label details ‘ Calymna costulata, Auckland, XVI p. 171’, in Hutton’s handwriting (i.e., CMNZ 2017.17.11), which is probably primary type material (see radula description by Hutton 1883d: 136).
Label details. CMNZ M294—‘38. Calymna costulata Hutton, Auckland’, pillbox label in Hutton’s handwriting.
Type locality. ‘ Auckland (T. F. Cheeseman)’ Hutton (1882p: 281, 1883d: 136).
Previous illustrations of type material. Radula teeth illustrated by Hutton (1884b: pl. 10, fig. D) probably from type material; Pilsbry (1893 [in 1893–1895]: 346, pl. 3, figs. 20–22—‘ Type. Suter, del.’); Suter (1915: pl. 26, figs. 15, a, b—possibly type material).
Remarks. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1882, but publication was delayed until May 1883 (Hutton 1883d: 136), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1882p: 281). A description by Hutton (1884b: 171) of a radula of costulata was probably based on the putative type material in CMNZ 2017.17.11 mentioned above. Amphidoxa costulata Hutton, 1882 is the type species of Calymna Hutton, 1883, by original designation, and of Flammocharopa Climo, 1970, also by original designation. As noted in the section on Hutton’s genus group names (above), Calymna Hutton, 1883 has been incorrectly interpreted as a homonym of Calymma Hübner, (1816–1826) 1823 [Lepidoptera] by Pilsbry (1893 [in 1893–1895]: 17), Suter (1913: 671), Thiele (1931 [1929–1935]: 575), Zilch (1959 [in 1959–1960]: 222) and Schileyko (2001: 1025), based on a subsequent misspelling of the latter name as ‘ Calymna Hübner’ by Walker (1858: 13). Flammocharopa Climo, 1970 has the same type species as Calymna Hutton, and is a junior synonym.
Taxonomy. Calymna costulata (Hutton, 1882) —after Hutton (1883i: 532, 1884c: 199), Pilsbry (1893 [in 1893– 1895]: 346), Hedley & Suter (1893: 645), Suter (1894b: 241).
Distribution. New Zealand; North Island, currently interpreted as being widely distributed from Northland to Wairarapa (e.g., Suter 1913: 676, Climo 1970: 335, Powell 1979: 308), but examination of material in the AIM and NMNZ collections indicates that this refers to a species complex, and the identity and distribution of Hutton’s species need to be re-evaluated.
