Helix venulata Pfeiffer, 1857

Pl. 7, fig. E

Pfeiffer, 1857. Proceedings of the Zoological Society of London, 25: 108.

Type material: Lectotype, NHMUK 1996150 /1, and paralectotypes (2), NHMUK 1996150 /2–3 (dry shell material); ex Museum Cuming (Acc. no. 1829) . Lectotype designated by Marshall & Barker (2008: 76).

Label details: ‘ H. venulata Pfr. New Zealand’—in Pfeiffer’s handwriting.

Type locality: ‘New Zealand’ ( Pfeiffer 1857b: 108).

Remarks: Marshall & Barker (2008: 75–76) noted that most published records of Helix venulata from New Zealand [i.e., other than the type material], were based on misidentifications of other taxa, and the only specimens that they considered to be similar to the type material were from Maunganui Bluff, northwestern North Island. The lectotype is illustrated here for the first time (pl. 7, fig. E). Helix venulata Pfeiffer, 1857 is the type species of Psyra Hutton, 1883 by original designation (non Psyra Stål 1876, nec Psyra Walker 1860). Helix dimorpha Pfeiffer, 1853 [= H. dimorpha Reeve, 1852 ] was incorrectly listed as the type species of Psyra Hutton by Pilsbry (1892 [in 1892–1893]: 65), and the replacement name Allodiscus Pilsbry , by Pilsbry (1892a: 56), but Hutton’s 1883 designation takes precedence (ICZN Article 67.8).

Current Taxonomy: Listed as Allodiscus venulatus (Pfeiffer, 1857) by Marshall & Barker (2008: 75) and Spencer et al. (2009: 215).

Distribution: New Zealand; northwestern North Island ( Marshall & Barker 2008).
