from the Caribbean Sea of Colombia is described. The new species resembles morphologically but differs from it principally by its color and habitat. is brown or blueish brown and occurs under intertidal boulders strongly exposed to water movement. is pale brown to beige and lives exclusively in intertidal areas dominated by vermetid snails, exposed to heavy wave action. The entangled tubular shells of vermetids are cemented to each other and to a hard substrate like beach rock, forming a microhabitat for the new crab species and other porcellanids of the genera and . Large genetic distances between DNA sequences of the mitochondrial 16S rDNA gene from and confirmed that they comprise different species. is the 53 member of the West Atlantic porcellanid fauna.

When a species is introduced in a new location, it is common for it to establish itself when it finds favorable conditions in the receptor community with regard to interspecific interactions with native species. The azooxanthellate corals coccinea and are invasive species introduced in the Caribbean Sea, the Gulf of Mexico, and the Brazilian Southwest Atlantic. They are successful competitors for space, have multiple reproductive modes, and have high larval dispersion and recruitment, but studies on food and trophic relationships of the genus are still scarce.

The list contains 516 indigenous and nine introduced species. Among the former, 461 species are autobranchs and 64 are protobranchs.

The disjunct distribution of Alpheus simus Guérin-Méneville, 1856 in the western Atlantic, from Florida to the south of the Caribbean Sea and then from Rio Grande do Norte to Bahia in Brazil, suggests that Brazilian material may belong to an undescribed species. The examination of specimens previously identified as A.

- * Using integrative taxonomy, both morphological and mitochondrial genetic analyses were performed, revealing that neither Leptalpheus nor Fenneralpheus forms monophyletic groups, but confirming three distinct clades of Leptalpheus.
- * Three new shrimp species were identified, including Leptalpheus ankeri from the Caribbean and L. sibo from Nicaragua, and several taxonomical revisions were made regarding previously described species, highlighting their evolutionary relationships and morphological similarities
