Remark |
: |
To about 8 cm. Shallow marine and estuarine waters (Ref. 94508). The pleura of the second abdominal segment overlap those of the first and third segments, and the third pair of pereiopods lacks pincers. Rostrum well developed, laterally compressed, usually denticulate, seldom extending beyond scaphocerite. Carapace without subocular tooth posterodorsal to orbital angle. First pair of pereiopods symmetrical, ending in clearly distinct pincers, broader than second pair, but not considerably enlarged. Second pair of pereiopods with carpus segmented, pincers small. Colour: no particular diagnostic colours nor colour patterns. Only Exhippolysmata hastatoides and Lysmata seticaudata are of some interest to fisheries (Ref. 104052). |
