Limnaea leptosoma Hutton, 1884

Pl. 1, fig. J

Hutton, 1884. New Zealand Journal of Science, 2: 175.

Type material. Possible syntypes, CMNZ M360 (1); NMNZ M.125540 [ex H. Suter colln.] (2) (dry shells). Hutton (1885c: 55) noted that he had “two specimens only” of this species, which indicates that at least one of the shells in the two lots listed here is not primary type material .

Label details. CMNZ M360 —‘17. Limnaea leptosoma Hutton,Wellington’,pillbox label in Hutton’s handwriting ; NMNZ M.125540—‘ Limnaea leptosoma Hutton, Syntype, Wellington, Hu.’ in H. Suter’s handwriting .

Type locality. ‘Wellington’ (Hutton 1884h: 175, 1885c: 55).

Previous illustrations of type material. Hutton (1885c: pl. 12, fig. 3).

Remarks. Hutton submitted a description of this species to the Transactions and Proceedings of the New Zealand Institute issue for 1884, but publication was delayed until May 1885 (Hutton 1885c: 55), and was preempted by a brief description in an account of a meeting of the Philosophical Institute of Canterbury (Hutton 1884h: 175). Treated as a junior synonym of Succinea tomentosa Pfeiffer, 1855 by Hubendick (1951: 192) and Dell (1956: 76). As noted in the preceding species entry, the latter taxon has a wide distribution in the North Island and South Island and is probably endemic to New Zealand.

Current taxonomy. A junior synonym of Austropeplea tomentosa (Pfeiffer, 1855) — Hubendick (1951 —in Lymnaea), Dell (1956: 76 —in Simlimnea Iredale, 1943).
