Uroptychus nitidus ( A. Milne-Edwards, 1880) View in CoL

Uroptychus nitidus View in CoL has previously been reported as Diptychus nitidus (see Baba et al. 2008). Specimens and types have been collected throughout the Caribbean and through the Straits of Florida ( Chace 1942; Pequegnat & Pequegnat 1970; Baba et al. 2008); specimens that were measured were from these water bodies from depths of 205 to 1488 m. Specimens of U. nitidus were collected in all months except February and October ( Fig. 3 View FIGURE 3 D); ovigerous females were collected in every month except February, March, October, and December ( Fig. 3 View FIGURE 3 D). Ovigerous females were significantly larger than non-ovigerous females (t-test, df = 138, t = 3.836, p<0.001). Ovigerous female CW ranged from 3.0 to 9.8 mm (73 measured); non-ovigerous female CW ranged from 1.3 to 9.1 mm (67 measured). Males and females were not significantly different in size (t-test, df = 285, t = 0.839 p = 0.402); male CW ranged from 2.1 to 9.1 mm (147 measured). Fecundity was significantly correlated with size, but is not a predictive indicator (R2 = 0.140, p = 0.003), and females had between one and 24 eggs. Carapace width was significantly correlated with egg diameter (R2 = 0.446, p <0.001); average egg size was between 0.90 mm and 2.12 mm, which is consistent with previously published egg sizes ( Milne-Edwards & Bouvier 1897).
