Abstract The family Santiidae consists of five genera and 29 species at present, included in the Suborder Asellota. In the northwest Atlantic this family is represented only by the genera Santia (two species), Halacarsantia (one species) and Spinosantia (one species). The present paper deals with the description of a new species of the genus Halacarsantia , collected at the Sisal Coral Reef System, Yucatan, Veracruz. The new species of Halacarsantia represents the 29 th asellote isopod discovered in the Gulf of Mexico and brings the total number of species of Halacarsantia to eight. The main differences between the new species and all others in the genus are: mandibular palp present; frontal lobe 0.5× as wide as maximum width of head, with 18 robust setae; coxae of all pereopods dorsally visible; eyes directly settled on each sides of head. A key to the species of Halacarsantia is included.
