Merus 1.1 × length of carapace (male), with several spines in addition to 4 distal marginal spines (1 dorsal at distal third, 1 mesiodorsal around midlength, 2 mesial equidistant between proximal and distal ends, 1 or 2 mesioventral on distal half), and 5 spines on distal margin including ventromesial spine. Carpus slightly narrowed proximally, 0.90–0.96 × length of merus; with 1 dorsal spine at midlength (proximally followed by 2 additional smaller spines in male), 2 or 3 spines on mesial margin, and 6 terminal spines (3 dorsal, 1 mesial, 1 lateral, 1 mesioventral). Palm slightly broader at midlength, equally broad at distal and median parts or gently narrowed proximally, 2.6 × (male), 2.3–2.7 × (females) longer than broad, 1.5 × (male), 1.3–1.5 × (females) length of carpus, moderately depressed (height 0.7 × breadth), mesial margin roundly ridged; proximally with denticle-like small dorsal spine, smooth elsewhere. Fingers incurved distally, crossing when closed, not gaping in both sexes; movable finger 0.5–0.6 × as long as palm, opposable margin with low, blunt process at proximal third; opposable margin of fixed finger with no distinct process.

. The P2–4 (walking legs), all detached from the body, are presumed to be as such in the above description. The only character to determine which is which pereopod is the length-breadth ratio of the merus, and possibly the flexor marginal spines, which may be four on P2 and fewer on P3 and P4. The seven pereopods not illustrated here cannot be determined by their position, so the actual morphological variations cannot be shown in the description.
