Amphidoxa perdita Hutton, 1883 View in CoL

Pl. 3, fig. H

Hutton, 1883. New Zealand Journal of Science, 1: 476.

Type material. Lectotype (designated here), CMNZ M275.1 View Materials , paralectotypes, CMNZ M275.2 View Materials – 4 View Materials (3), CMNZ M276 View Materials

(3), CMNZ M1067 [ex ZS 710] (6), CMNZ M12782 View Materials [ex M276] (1) (dry shells); possible paralectotypes, NMNZ M.275988 [ex H. Suter colln.] (3) (dry shells). The molluscan collection at CMNZ has a radula and jaw mounted on a glass slide with the label details ‘ Amphidoxa perdita, Greymouth, XVI p. 179’, in Hutton’s handwriting (i.e., CMNZ 2017.17.19), which is probably primary type material (see descriptions of radula and jaw by Hutton 1884b: 179, pl. 11, figs. C, Q).

CMNZ molluscan catalogue details. M275—‘ Flammulina perdita Hutton , Auckland (4 specimens) (old No. 37)’; M276—‘ Flammulina perdita Hutton, Greymouth (4 specimens) (old No. 37)’; M1067—‘ Flammulina perdita Hutton , Auckland (7 specimens) (old number ZS 710 ) ’.

Label details. NMNZ M.275988—‘91, Flammulina perdita Hutt., Greymouth, Hel. ’, in H. Suter’s handwriting.

Type locality. ‘ Auckland (Cheeseman)’ ( Hutton 1883g: 476), ‘Greymouth (R. Helms)’ ( Hutton 1884b: 179).

Previous illustrations of type material. Jaw and radula teeth illustrated by Hutton (1884b: pl. 11, figs. C, Q) probably from type material; shell(s) illustrated by Pilsbry (1892 [in 1892–1893]: pl. 22, figs. 73–75, ‘H. Suter, del.’) and Suter (1915: pl. 9, figs. 12, a, b) may be from the type series.

Remarks. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1883, but publication was delayed until May 1884 ( Hutton 1884b: 179), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury ( Hutton 1883g: 476). Locality details listed by Hutton (1883g: 476, 1884b: 179) indicate that the original description of Amphidoxa perdita was based on a type series that included material collected in Auckland by Thomas Cheeseman and in Greymouth by Richard Helms. A lectotype is designated here from the Auckland material (CMNZ M275.1), and is illustrated in pl. 3, fig. H. This species has a very wide distribution in New Zealand (below). From Pilsbry (1893 [in 1893–1895]: 18) and Hedley & Suter (1893: 643) onwards, perdita has generally been assigned to Flammulina Martens, 1873 at subgenus or genus level.

Current taxonomy. Flammulina perdita (Hutton, 1883) — Hedley & Suter (1893: 644), Suter (1913: 680), Powell (1979: 314), Spencer et al. (2009: 215).

Distribution. New Zealand; North Island and offshore islands, including Marotere/Chicken Islands, Taranga/ Hen Island, Aotea/Great Barrier Island, Hauturu/Little Barrier Island, Tuhua/Mayor Island, Kapiti Island; South Island and nearshore islands in Marlborough Sounds and Fiordland; Whenua Hou/Codfish Island, Rakiura/Stewart Island and nearshore islands ( Suter 1913: 680; Dell 1954b: 142; Powell 1979: 314; AIM and NMNZ collection records).
