Zoeae rapidly beat their maxillipeds to swim and generate feeding currents (Foxon, 1934), and efficient locomotion relates to the size and cross-sectional area of maxillipeds and attached setae (Chia et al., 1984).
To detect this chemical, however, the robot had to draw the released chemical to its sensors with the help of the water currents generated with the maxilliped arms.

The stomodeum is also clearly visible, and there is an initial differentiation of the mandibules, maxillules, maxillae, and maxilliped primordia.
Sewell's (1940) and Ummerkutty's (1960) descriptions of the armature complement of the mandible, maxillule, maxilla and maxilliped lack the necessary detail and comparison with the new species presented herein could cause confusion.

alata Campos 1989, but can be distinguished from it by smooth upper margin of third maxilliped merus, the size and shape of apex of first gonopod, and the internal lobe or papilla of spermatic channel, which is concave, raised, with ends with minute papillae or rounded tubercles.
