Sars, 1870 ] ( Figures 29A, B ) 1874a: 280 [X: 206]—available name Type material. MCZR–M–16129 —11 sh, more or less damaged “Amphisphyra quadrata Monts Pal. e S. Vito!” // 1 sh + 1 frg “S. Vito” Type locality. Described from San Vito lo Capo and Palermo ( Sicily ). Remarks. Regarded as a synonym of Colpodaspis pusilla M. Sars, 1870 , by both Lemche (1948: 40) and Oliverio & Tringali (2001: 129; 124, fig. 10, 125, figs 17–19). As noticed by the latter, “ Diaphana quadrata (Monterosato, 1874) ” sensu Nordsieck (1972: 25; 235, fig. 4) does not seem to belong to the present species. The drawing by Nordsieck seems to fit an undescribed species of the genus Diaphana T. Brown, 1827 , figured by Oliverio (2000: 47, fig. 12) and currently in study by one of us (LPT). Recorded by MolluscaBase (2018) as a synonym of Colpodaspis pusilla M. Sars, 1870 .
