Hydrocena (Omphalotropis) vestita Pfeiffer, 1855 View in CoL

Pl. 10, fig. A

Pfeiffer, 1855. Proceedings of the Zoological Society of London, 23: 106.

Type material: Syntypes (4), NHMUK 20160068 About NHMUK (dry shell material); ex Museum Cuming (Acc. no. 1829) .

Label details: ‘ New Zealand, Mus. Cuming’.

Type locality: Vanuatu (below); incorrectly stated as ‘ New Zealand’ by Pfeiffer (1855: 106) .

Remarks: There are no previous illustrations of the type material of Hydrocena (Omphalotropis) vestita Pfeiffer. It was described from specimens in the Cuming collection that were reportedly from New Zealand, and was listed by subsequent authors as being from that country (e.g., Pfeiffer 1858: 166; Cox 1868b: 61; Pease 1869: 139; Hector 1873: 25; Hutton 1880: 40, 1884b: 211; Hedley & Suter 1893: 622; Suter 1894d: 225, 1904a: 78; Kobelt & Möllendorff 1897: 71; Kobelt 1906: 84). Suter (1913b: 198) noted that it “has never been found again, and it is doubtful whether the type was really found in New Zealand ”. During the present study, Hiroshi Fukuda (pers. comm. 2016) pointed out that Hydrocena (Omphalotropis) vestita Pfeiffer, 1855 is a subjective senior synonym of Omphalotropis conella Sykes, 1902 . A syntype of the latter (NHMUK 1902.12.1.260) is illustrated in pl. 10, fig. B. The type locality of O. conella is ‘Port Fila, Efate’ in the New Hebrides [= Port Vila, Vanuatu] ( Sykes 1902: 200), and Pfeiffer’s species is here assumed to be from Vanuatu as well. Solem (1959) included O. conella , along with two other Vanuatuan species, in section Lyrotropis Solem, 1959, based on shell, operculum and radular characters. He noted (Solem: 1959: 201–202) that these three species formed a ‘very isolated group’ that differed markedly from other western Pacific Omphalotropis taxa. Fukuda & Ponder (2003: 2026) listed Lyrotropis as a genus-level taxon.

Taxonomy: Treated here as Lyrotropis vestita (Pfeiffer, 1855) n. comb.

Distribution: Vanuatu; Efate, Espiritu Santo and Maewo ( Solem, 1959: 203, 1962: 241).
