 2** little longer in d than in 9. Eyes large, rounded, convex, dark red. 

 Antenna 1 about as long as body; flagellum longer than ultimate Joint of 

 peduncle; accessory flagellum minute, 3-jointed, middle Joint much the longest. 

 Antenna 2 much shorter. Both antennae sparsely setose with short setae. 

 Gnathopod 1 as in D. pon-ecta. Gnathopod 2 in d, 2^ Joint widened except
