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 antennule, antenna, maxillule
, mandible, maxilla, maxilliped, and first leg were at the cephalothorax.
swollen at base, tipped with stout claws (Figure 2c).
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.

hospitalis Fraser, 1920 by having in the female a genital complex that is at least half the length of the cephalothoracic shield (including frontal plates) and with small, rounded posterolateral lobes, a 1-segmented abdomen that is less than one-quarter the length of the genital complex, a maxillule
with two large tines on the dentiform process, a maxilliped without a myxal process, a pair of non-bifid tines on the sternal furca, the spine on the first exopodal segment of leg 3 inserted distally on the basal swelling, a 3-segmented leg 4 exopod, and the inner lobe of leg 5 not protruding beyond the posterior margin of the genital complex.
