Uroptychus minutus was collected in the Gulf of Mexico, although the type specimen is from Trinidad at 134 m ( Benedict 1902). A total of 19 specimens was measured from the Gulf of Mexico in depths of 46 to 81 m ( Fig. 2 View FIGURE 2 ): seven females, four ovigerous females, and eight males; one ovigerous female was not measured. Specimens were only collected in May and June; ovigerous females were collected in both months ( Fig. 3 View FIGURE 3 C). Males CW ranged from 2.3 to 4.7 mm. Non-ovigerous females had CW of 2.1 to 3.5 mm; ovigerous females had CW of 3.4 to 3.8 mm. Ovigerous females and non-ovigerous females were not significantly different in size (t-test, df = 8, t = 1.823, p = 0.106). Males and females were not significantly different in size either (t-test, df = 15, t = 0.579, p = 0.571). No significant correlation existed between fecundity and the size of the ovigerous female (R2 = 0.324, p = 0.655). Ovigerous females had between one and eight eggs, and the average egg diameter for each female was between 1 mm and 1.4 mm. However, the sample size was not large enough to make definitive statements about this species.
