Decapod genera

Tanaocheles is a genus of crabs, the only genus in the family Tanaochelidae. It contains two species, T. bidentata and T. stenochilus. The two species were formerly placed in different families, and they were only shown to be related, and placed in a new subfamily (now elevated to the taxonomic rank of family), in 2000.

Paromola is a genus of crabs within the family Homolidae. Members of the Homolidae genus have their fifth pereiopods (last pair of walking legs) in a sub-dorsal position, which allows them to hold objects, such as sponges, black corals and gorgonians, over the rear half of the carapace, in a possible defence mechanism against predators.

Both genera are members of the family Parastacidae, a family of freshwater crayfish restricted to the Southern Hemisphere.

Glyptoxanthus is a genus of crabs in the family Xanthidae, containing eight species. It was originally erected by Alphonse Milne-Edwards in 1879 for six species previously placed in the genus Actaea and elsewhere.

Cyclodius is a genus of crabs in the family Xanthidae, containing the following species:

Pseudodromia is a genus of crabs in the family Dromiidae, often referred to as sponge crabs. They are small or medium-sized crabs which get their name from the ability to shape a living sponge into a portable shelter for themselves. A sponge crab cuts out a fragment from a sponge and trims it to its own shape using its claws. The last two pairs of legs are shorter than other legs and bend upward over the crab's carapace, to hold the sponge in place. The sponge grows along with the crab, providing a consistent shelter.

Nanosesarma is a genus of crabs belonging to the family Sesarmidae.

Selatium is a genus of crabs in the family Sesarmidae.

Allacanthos is a genus of crabs in the family Pseudothelphusidae

Paracrangon is a genus of deep-sea shrimp in the family Crangonidae, found on the Pacific coasts of North America, Asia, and Australia. Morphologically, they are notable for several autapomorphies, most significantly their unique lack of second pereopods, but also for their partially flexible abdomen, which allows them to assume their defensive cataleptic posture. Species also have long spines covering their carapace. They are distinctive among the Crangonid shrimp, and are almost certainly monophyletic. All species except Paracrangon echinata, the type species, are quite rare.
