Vultocinus anfractus is a species of crab, the only species in the family Vultocinidae. It has been found around the Philippines, Vanuatu and New Caledonia, and lives on driftwood. Its discovery forced a reappraisal of the relationships within the superfamily Goneplacoidea, and to the recognition of Mathildellidae, Conleyidae and Progeryonidae as separate families.
Tanaocheles is a genus of crabs, the only genus in the family Tanaocheleidae. 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, in 2000.
Bellia picta is a species of crab that lives around the coasts of South America, and the only species in the genus Bellia. On the Atlantic coast, it is found in Rio Grande do Sul, Brazil, while on the Pacific coast, it is found off Peru and Chile. It probably lives in burrows and is a filter feeder.

Smalleyus is a genus of crabs in the family Pseudothelphusidae, containing the single species Smalleyus tricristatus.
Brasiliothelphusa tapajoensis is a species of freshwater crabs in the family Pseudothelphusidae, and the only species in the genus Brasiliothelphusa. It was described in 1986 from specimens caught in the Rio Tapajós in the state of Pará, Brazil. It is listed as Data Deficient on the IUCN Red List.
Epilobocera is a genus of crabs in the family Epiloboceridae. It is the only genus in its family; this taxonomic arrangement follows the revision of the family Pseudothelphusidae by Álvarez and colleagues.

Chaceus is a genus of crabs in the family Pseudothelphusidae, containing the following species:
Karstarma is a genus of karst-dwelling crabs formerly included in Sesarmoides.
Cyrtocarcinus truncatus is a species of crab in the family Xanthidae that lives in the waters around Hawaii. It was described in 1906 by Mary J. Rathbun as Harrovia truncata, based on a single immature male specimen caught near Kauai. Masatsune Takeda transferred the species to his new genus Glyptocarcinus in 1979, and Peter Ng and Diana Chia erected a new genus, Cyrtocarcinus, for this species alone, in 1994.
Euryxanthops is a genus of crabs in the family Xanthidae. It was originally established in 1983 by Garth & Kim to contain three species of deep-water crabs from Japan and the Philippines - Euryxanthops dorsiconvexus, Euryxanthops flexidentatus and Euryxanthops orientalis. Since then, several more species of this genus have been identified and described, and Euryxanthops currently contains:
Linnaeoxanthus is a genus of crab, whose only species is Linnaeoxanthus acanthomerus. Linnaeoxanthus is the only genus of the family Linnaeoxanthidae.
Marratha angusta is a species of crabs in the family Xanthidae, the only species in the genus Marratha. It was originally described as Cycloxanthops angustus by Mary J. Rathbun in 1906, but was moved to a new genus in 2003; the name of the genus, Marratha, is an "arbitrary abbreviation" of Rathbun's name. It has been recorded from the Amirante Islands (Seychelles), Hawaii and the South China Sea.
