Alpheus tricolor
''Alpheus tricolor'' is a crustacean belonging to the family of snapping shrimp. It was first isolated in Indonesia and Sri Lanka. It counts with a setose carapace, an acute rostrum, shallow adrostral furrows and a basicerite with a strong ventrolateral tooth. The lamella of its scaphocerite is not reduced, with an anterior margin that is concave. Its third maxilliped counts with an epipodial plate bearing thick setae, while its first chelipeds are found with their merus bearing a strong disto-mesial tooth; its third pereiopod has an armed ischium, with a simple and conical dactylus. Its telson is broad, distally tapering, with 2 pairs of dorsal spines. The species is named after its characteristic colour pattern, including white, red and orange.〔Anker, Arthur.

==Description==
''Alpheus tricolor'' has a carapace length of about , a total length of and chela length of . Its carapace is smooth, possessing shallow grooves latero-anteriorly, and erect setae dorsally.

Its eyes have small anterior processes, and its antennular peduncles are stout.〔
Its antenna shows a basicerite bearing an acute, ventrolateral tooth. Its mouthparts are typical for ''Alpheus'': its mandible with a 2-jointed palp, its incisor process bearing about 12 teeth, and showing a stout molar process; its maxillula has a bilobed palp, while its maxilla shows no characteristics of note.〔
The surface of each somite on its abdomen bears conspicuous setae that are proximal to its dorsoposterior margin. Its uropodal exopod has a strong lateral spine, and a sinuous diaresis. The species' telson is broad, distally tapering, exhibiting 2 pairs of dorsal spines in deep depressions; it counts with numerous long setae between lateral spines.
