Habitat: The species ranges bathymetrically from 110–1660 m ( Sirenko 2004, Saito 2006a).

Distribution: Known from the Pacific coast of Southern Japan ( Saito 2006a: 210), East Chinese Sea, Vietnam, Philippines, Indonesia to Vanuatu and Fiji ( Sirenko 2004: 112). The westernmost record is from the Andaman Islands ( Sirenko 2004: 112).

Remarks: This deep water species is associated with sunken plant remains and is not uncommon in the examined area.

Kilias (1995: 166) selected a specimen of Lepidopleurus niasicus Thiele, 1906 as the lectotype, which he erroneously mentioned to be figured in pl. 29, figs 1–3 of Thiele (1906), unaware that at least two additional specimens had been collected. He did not mark which of the three wet preserved specimens he designated as the lectotype so that it remains unclear which specimen he chose, and thus his lectotype designation is invalid (ICZN Art. 74.5). The available material comes from three stations and no type locality was ever fixed. To avoid further misidentification of the name-bearing type, the specimen from station 203, preserved flat and with all valves in situ, measuring c. 6.4 x 3.2 mm, is here selected as the lectotype ( Figure 1 D), with “ Indonesia, Northwest off Nias Island, 01°47.1’N 96°58.7’E, Valdivia St. 203, 660 m “ as the restricted type locality. The two paralectotypes are as follows: 1 specimen slightly curled, no valves present, from VALDIVIA station 194; and the other specimen preserved flat, all valves in situ, measuring 4.9 x 2.5 mm, from VALDIVIA station 199.
