Lepidophthalmus Louisianensis

A new species of Lepidophthalmus lacking a ventral median sclerite on the second abdominal somite is described from coastal waters of the southwestern Gulf of Mexico. Lepidophthalmus statoni sp. nov., originally recognized only as a unique population in allozyme studies, is sympatric with the ventrally plated species Lepidophthalmus manningi Felder & Staton, 2000, but more closely resembles Lepidophthalmus louisianensis (Schmitt, 1935) from the northern and northwestern Gulf of Mexico. Apparently restricted to intertidal and shallow subtidal tropical waters, the new species is known to range from western Campeche to middle-upper reaches of Veracruz, Mexico. As many members of the genus, it commonly inhabits euryhaline inlets, estuaries, and protected shorelines, including richly organic muddy to clayey sands and sandy muds adjacent to shoreline vegetation. Coloration is documented and discussed as a tool to facilitate field identifications, as are morphological characters.

Enhydrosoma texana sp. nov. is described from the northern Gulf of Mexico. The new species is closely related to E. parapropinquum Gómez, 2003 from northwestern Mexico. Both species share several characters including an elongated cylindrical caudal ramus, an abexopodal seta of antennae, the structure of mouthpart appendages, seta formula of thoracic legs P1–P4, the shape of the P5 exopod in the female and the apophysis structure of P3 in males. However, the new species is distinguishable from E. parapropinquum by the shape of the rostrum, number of the antennular segments, the shape of the mandibular palp, the relative lengths of the thoracic legs, the shape of the apophysis of P3 in the male, setal number and length of the P5 exopod of the female, the length of the seta on P5 in the male and the relative lengths of the caudal ramus in both sexes. This is the deepest record of a species in the genus Enhydrosoma.

A New Species

The genus Ameroculodes Bousfield and Chevrier, 1966 is emended to accommodate a new species of oedicerotid amphipod, Ameroculodes miltoni, common to estuarine habitats of the southeastern United States. In this region the new species has been confused with Ameroculodes (=Monocu- lodes) edwardsi (Holmes, 1905) and Deflexilodes (= Monoculodes) intermedius (Shoemaker, 1930), both of which are distinctly larger and endemic to the cold temperate waters of the Northwest Atlantic. Ameroculodes miltoni can be distinguished from A. edwardsi by (1) having the postero-ventral margins of epimeral plates 1-3 rounded, (2) a short, blunt rostrum, (3) uropod 2 with relatively few dorsal spines on the peduncle, (4) and a subovate telson. Deflexilodes intermedius, like A. miltoni, has rounded epimeral plates, but is readily distinguished by the well-developed, elongate dactyls on its 3 rd and 4 th pereopods. Ameroculodes miltoni occurs over a wide range of salinities (<1°/ °° to 35°/ °° ) and is most common in medium to fine sand or sand-silt substrata. It appears to be an important biotic component of northern Gulf of Mexico estuaries.

A new deep-water species of the snapping shrimp genus Alpheus Fabricius, 1798 is described from two offshore localities in the northern Gulf of Mexico, south of Louisiana. Alpheus lentiginosus n. sp. belongs to the A. macrocheles (Hailstone, 1835) species group and is most closely related to the western Atlantic A. pouang Christoffersen, 1979 and A. amblyonyx Chace 1972, the eastern Atlantic A. platydactylus Coutière, 1897 and A. macrocheles (Hailstone, 1835), and perhaps also to the eastern Pacific A. exilis Kim & Abele, 1988. The new species is associated with deep-water soft sediments adjacent to clusters of Lophelia pertusa (L.) (Scleractinia) or mud-covered rocks and cobble, at a depth range of 336–438 m, thus representing the deepest-known record of the Alpheidae in the Gulf of Mexico and the entire western Atlantic.
