Antenna, antennula, maxilla, maxillule, maxilliped, pereon, pleon, pereopods, pleopods, pleotelson and uropods were mounted between a depressed slide and a coverslip for observation and measurement in a Leica EZ4HD stereomicroscope (Thatcher, Oliveira, & Garcia, 2009).

The aim of the present study is to compare the differences and similarities in the morphology of appendages (rostrum, carapace, first pereiopod, second pereiopod, fourth pereiopod) and mouthparts (third maxilliped, second maxilliped, first maxilliped, mandible, maxillule and maxilla) of A.
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.
