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.

Coral Reef System

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.

A New Species

The new tegastid species Smacigastes methanophilus sp. nov. is described from cold-seep samples collected from the Gulf of Mexico in 2006. Besides Smacigastes micheli Ivanenko & Defaye, 2004 and Smacigastes barti Gollner, Ivanenko & Martínez Arbizu, 2008, this is the third species of the genus Smacigastes Ivanenko & Defaye, 2004. To date, this genus contains the only species within the family Tegastidae known from deep-sea habitats. Furthermore, S. methanophilus sp. nov. is the first species of Tegastidae found at cold seeps and associated with tubeworm aggregations. It has the same primitive features as S. micheli but can be distinguished from the latter by the setation of second and third segments of female antennule and second segment of male antennule, the setation of the mandibular palp, the ornamentation of P5 exopod in both sexes, setation of male P5 exopod, form of the female P5 baseoendopod, and the different shape and length of the P5 setae in female. Moreover, both sexes of Smacigastes methanophilus sp. nov. are much smaller than those of S. micheli. Compared to S. barti, S. methanophilus sp. nov. differs in the segmentation and setation of female antennule, the setation of male antennule, setation of mandibular palp, setation of the maxillule, number of endites of the maxilla, number of setae in P1, the ornamentation of female P5 and setation in male P5.

A New Species

A new species of amphipod from the genus Metopelloides Gurjanova, 1938 (Crustacea: Amphipoda: Stenothoidae) asso-ciated with two species of sublittoral hermit crab species, Pagurus pectinatus (Stimpson, 1858) and Elassochirus cavi-manus (Miers, 1879) (Crustacea: Decapoda: Paguridae), is described from the Russian coasts of the Sea of Japan. The newspecies clearly differs from the congeners by the combination of morphological features such as telson without lateralspines, an elongated mandibular palp with single apical setae, the structures of distoventral palmar margins of subchelaon gnathopods I and II in females, bright white-red body coloration. Thus, the record of Metopelloides paguri sp. nov.represents the second record of the family Stenothoidae in the association with sublittoral hermit crabs from the Sea of Japan.
