Thymopides differs from related genera such as
Homarus,
Homarinus and
Nephrops in having the first pair of pereiopods of similar size and shape, rather than one "crusher" and one "cutter" claw. It differs from others, such as
Metanephrops and
Eunephrops by the lack of a
carina behind the antennal
spine, by the smaller size of some spines and by the smaller, unpigmented eyes. ==Taxonomy==
