Diaphana quadrata


quadrata, Amphisphyra   [ Colpodaspis pusilla M. Sars, 1870   ] ( Figures 29A, B View FIGURE 29 )

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   .
