The rostrum of this species is long and curves upwards at the distal end, extending well beyond the antennal scale and forming a prominent basal crest above the eye. The upper edge of the rostrum is armed with 11 to 14 teeth, while the lower edge has 8 to 14 teeth. The hepatic spine is distinctly below the antennal spine. The second legs are remarkably large and robust, with the carpus longer than the merus. In adult males, there are 1 or 2 large basal teeth, and no rows of tubercles are present on either side. The movable finger is densely hairy, especially towards the tip, and the carpus is shorter than the pincer. The telson regularly tapers to a sharp point, lacking a posterior margin, and the tip extends beyond the posterolateral spines. In adult males, the carapace is smooth, and the second pair of pereiopods is spinous. The cutting edges of the fingers have 1 or 2 large proximal teeth, while the rest of the edges are entire, without rows of tubercles on either side. The movable finger is covered with a dense velvety pubescence, and all joints of pereiopods are either naked or have a few small and scattered spinules or hairs. The carpus is shorter than the propodus. The body typically exhibits a dark green to greyish-blue color, with longitudinal or irregular streaks of darker and lighter hues. The hinges of abdominal segments often have an orange tint, and the eyes are dark brown. The antennal flagella range from dark blue to greyish, while the large pincer appears bluish to dark blue. Eggs have a yellowish color, and young individuals and berried females may have some longitudinal golden strips on the body sides. Sexes are generally distinguished by the presence of gonopores at the bases of the fifth or third leg in males and females, respectively. Another method involves examining the second pleopods, where males possess an appendix masculina in addition to the appendix interna found in both sexes. The maximum body length reaches 340 mm in males and 260 mm in females, commonly ranging between 100 and 200 mm.
