M); as consequence, the tuft of scratching setae of the apex seems more conspicuous. In thoracopods 1 through 10, all over the medial margin, from its distal to its proximal part, the curved setae gradually become straight and at the same time sinuous in their tip, whereas in the proximal part of the margin the setae are curved in the opposite direction of the distal setae; the setae are almost uniform in length along the margin. From thoracopod 7 trough 10, a group of setae in the lower and the medial margins are sub-marginally inserted (

In the male, the distally extended triangular endopodites of the 10 former thoracopods of the series bear a cuticular reinforcement along the medial margin lacking in the shorter sub-rectangular to suboval endopodites of the female. This structure is also observed in the male endopodites of other
