A new species of amphipod of the genus Lysianopsis from the Veracruz Coral Reef System, SW Gulf of Mexico is described. Lysianopsis adelae n. sp., was collected in the sediments at the base of the sponge Aplysina fistularis at a depth of 10 m. The differences among L. alba, L. hummelincki, and L. ozona, recorded from Gulf of Mexico and Caribbean Sea are pointed out and they are compared with the new species.

A new species of Leptostraca, Nebalia villalobosi, is described from the Veracruz Coral Reef System, SW Gulf of Mexico. The new species was found associated with the sponge Ircinia fistularis (Demospongiae) from the Blanquilla reef at a depth of 12 m. It differs from the closely related species N. longicornis and N. lagartensis in the form of the eyes and rostrum, the number of articles in the antennular and antennal flagella, the inner border of article 3 on the mandible palp, the length of the exopod of maxilla 2, the rounded denticles on pleonite 6, the enlarged tip on pleopod 5, and the caudal furcae being slightly longer than the telson and pleonite 7 combined. This is the first record of a leptostracan associated with the sponge Ircinia fistularis.

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 29th 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.
