A New Species

AbstractA new species of parasitic nematode, Philometra mexicana sp. nov. (Philometridae), is described based on males and females parasitizing the gonads of the marine perciform fish (rock hind) Epinephelus adscensionis (Osbeck) (Serranidae) off the coast of the southern Gulf of Mexico (reefs of the Enmedio Island, Veracruz), Mexico, collected on 10 April 1990. The new species is characterized mainly by very small males (body length 1.63–1.86 mm) with equally long, needle-like spicules (length 90–120 μm) and the gubernaculum (57–66 μm) without the usual dorsal barb on the distal end, the body length of gravid females (178–230 mm), the presence of a well-developed anterior bulbous inflation on the female oesophagus, and by the length of the first-stage larvae (420–435 μm). A comparison with other congeners parasitizing the gonads of marine fishes is provided. The cephalic end of the gravid female of Philometra margolisi Moravec, Vidal-Martínez et Aguirre-Macedo, 1995, another related species from the gonads of Epinephelus [E. morio (Valenciennes)] in Mexico, has been studied by SEM for the first time; it confirms the arrangement of the cephalic papillae as reported in the original species description. Philometra mexicana is the fifth species of Philometra reported from the gonads of marine fishes in the West Atlantic region.

Abstract Engraulicola lamothei n. sp. (Monogenea: Gastrocotylidae) is described from the gills of Chloroscombrus chrysurus (Teleostei: Carangidae) from Veracruz, southern Gulf of Mexico. This monogenean is 1110-1670 (1328) µm long and 260-550 (363) µm wide. The haptor is asymmetrical, the long side has several clamps (35-42), and the short side has a single clamp; the posterior end has a small lappet armed with two dissimilar pairs of hooks. Male and female genital pores open near the anterior body end; the male genital pore is ventral, armed with a corona of 12 spines; the female pore is dorsal and unarmed. The new species differs from Engraulicola forcipopenis George, 1960 and from Engraulicola micropharyngella Unnithan, 1967 by lacking a pair of pointed forceps-like spines at the end of the penis amid the corona spines, and from Engraulicola thrissocles Tripathi, 1959 by the number of clamps on both sides, the number the hook pairs on the terminal lappet and the testis number. This is the first record of the genus Engaulicola George, 1960 on the Atlantic West Coast.

In the oceanic zones of the Gulf of Mexico a new species of diatom was found belonging to the genus Halamphora. Live cells were isolated using basic microbiological techniques for culturing and DNA analysis. Observations to determine morphological and morphometric characteristics were performed by both light and scanning electron microscopy. In addition, a phylogeny was built based on the expression and sequencing of the small subunit of the 18S gene. As a result of these observations, we conclude that this pennate diatom is a new species here proposed as Halamphora oceanica.

A New Species

Gammaropsis elvirae sp. nov. is described and illustrated here, as a new species of the family Photidae Boeck, 1871, occurring on sites widely distributed in the soft-sediment habitats from the Yucatan shelf, southern Gulf of Mexico. This new species differs from all other congeners by a unique set of characteristics: lateral cephalic lobes rounded; outer lobes of lower lip with one cone on each lobe; gnathopod 1 propodus longer than carpus; gnathopod 2 propodus enlarged with small convoluted processes on posterior margin and palmar angle undefined; gnathopod 2 dactylus short, less than one half in length of propodus; dense setation on basis, carpus, and propodus of gnathopod 2; epimeral plates 1–3 rounded; inner ramus of uropods 1–3 longer than outer ramus; and telson emarginated. Ecological comments on spatial distribution and associated environmental variables are included, as well an identification key to the genus in tropical America.

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.
