Male individuals of this species possess distinct characteristics.Their carapace takes on a triangular shape when viewed laterally and is clearly separated from the head, exhibiting a dorsal depression. Males have relatively larger heads and eyes compared to females, and the lower edge of the carapace is more sharply curved. The distal segment of the first leg’s endopodite features a robust and inwardly curved hook. Additionally, their copulatory organ is cylindrical, with longitudinal grooves at the distal end. In contrast, female individuals present their own unique features.When observed from the side, the carapace may appear either oval or triangular, depending on the developmental stage of the embryos. The brood pouch tapers towards the posterior and can have a pointed or somewhat rounded shape, often adorned with a short spine. Females have relatively small heads in proportion to their body size, with a regularly rounded anterior shape and a slight convexity near the antennulae. Although they have large compound eyes, these eyes do not extend to occupy the entire forehead. The antennulae in females are diminutive, fused at the base, and appear pointed in lateral view with a rounded distal end, typically bearing 3-4 elements. Their legs are relatively short, and the first leg is not elongated. The postabdomen is notably short and bifurcated. Remarkably, the brood pouch can accommodate as many as 7-8 embryos.
