Paralomis aspera has a pentagonal carapace which is as wide as it is long – the female holotype's measuring 113 mm (4.4 in) long and 113 mm (4.4 in) wide. [1] Its rostrum is short [a] and comprises three spines, and the gastric, cardiac, and branchial regions of the carapace are prominent and well-defined. [1] Both the carapace and abdomen are thickly covered with tubercles, each of which are surrounded by a ring of setae. [1] Its chelipeds are densely spinose, and the right is more robust than the left. [1] Its walking legs – long and robust, the rearmost pair measuring 255 mm (10.0 in) in the female holotype – are similarly spinose. [1]
Paralomis aspera has been found off Colombia and Peru at depths ranging from 560–1,270 m (1,840–4,170 ft). [2]
Paralomis aspera was described in 1893 by American carcinologist Walter Faxon. [1]
