Antenna 2 may develop plumose setae on article 5 and the flagellum when individuals are approaching maturity, though small individuals that appear to be otherwise adult may not develop plumosity. This occurs in both sexes. The mandibular palp article 2 may bear a row of setae on the dorsal margin in a few species. The maxilla 1 may bear a cluster of setae at its base though most species lack these setae. Akey character is the presence or absence and length of a single or cluster of setae on the anterodistal margin of the carpus at the junction of the propodus in gnathopod 1. If present, these setae may be slightly medial or lateral. The bases of gnathopods 1 and 2 may or may not possess a row of setae and the presence and length of these setae is a key character for species definition. The propodus of gnathopod 2 may have a concave or sinuous palm in the juveniles and adult females. Large subadult males may have a small thumb, termed a “pre-thumb” at the location where the much larger thumb will appear at the last molt. Small subadults of the same species do not exhibit a pre-thumb. At the terminal molt, the thumb may be long or short, sinuous or straight, incised, acute or squared at the tip. “Major form males” have larger thumbs than “minor forms”, but being at the terminal molt, a minor form does not transition into a major form. The minor form may have a tooth on the dactyl that fits into the palmar incision. In the major form, the dactyl is expanded on its inner margin close to the hinge. Most terminal molt species lose their palmar defining spines that are present in the juvenile; the female always retains these spines. For all species the number of spines defining the gnathopod palms may be occasionally 2 or 4 rather than the usual 3. The bases of pereopods 3 and 4 are wide with convex margins in juveniles and females but the bases are slenderer in the thumbed male. In a few species the propodus of pereopods 5–7 may be prehensile. The peduncular spinous process of uropod 1 is absent in some species. The number of major cusps adjacent to the recurved spine that tips the third uropod outer ramus may be rarely 3 or 4 rather than 2. The inner ramus bears extra spines mid-dorsally in some species. Unless noted otherwise, these interspecific differences apply to both sexes and all ages of a species.
