Gulf Of Tehuantepec

In the Tropical Eastern Pacific region, the gammaridean amphipods of the families Maeridae and Melitidae are represented by 28 species and 11 genera; the genus Elasmopus is the richest, with 13 species. The examination of approximately 3,250 specimens resulted in 12 new records from the Gulf of Tehuantepec, belonging to four genera, Elasmopus, Maera, Quadrimaera and Melita. All species are illustrated and described. Seven new species are described as: Elasmopus bastidai n. sp., Elasmopus karlae n. sp., Elasmopus lecroyae n. sp., Elasmopus marcelae n. sp., Elasmopus oaxaquensis n. sp., Maera umarae n. sp., and Melita bousfieldi n. sp. With these new species the genus Elasmopus from the Tropical Eastern Pacific is increased to 18 species that corroborates the hypothesis of Barnard (1979) “on the Pacific there are (sic) a mark of speciation of genus Elasmopus”. In addition, there are five new records from the Gulf of Tehuantepec: three species of Elasmopus and two of Quadrimaera. Also, the range distribution of Elasmopus temori Barnard and E. zoanthidea Barnard, is increased to the north from the Galapagos Islands to the Gulf of Tehuantepec; for E. tubar Barnard, Quadrimaera chinarra Barnard, and Q. reishi Barnard, there are new intermediate records between the Gulf of California and the Galapagos Islands. With the exception of the species of Quadrimaera, all known species represent the second record in the region after their first descriptions.

New records are provided for four species of decapod crustaceans in the eastern Pacific. Hymenopenaeus nereus (Faxon, 1893) was collected further north and further from the coast than previously known. The distribution of Heterocarpus hostilis Faxon, 1893 is extended from off Panama to off Mexico. Parhippolyte cavernicola Wicksten, 1996, previously known only from the type locality in the Gulf of California, Mexico, has been found in a cave in the Galapagos Islands, Ecuador. Moloha faxoni (Schmitt, 1921) is reported for the first time within the Gulf of California, Mexico.

A New Species

The family Chrysopetalidae has been poorly studied from the Pacific coast of Mexico compared to other families. Specifically from the southern Mexican Pacific, only two species of the family have been recorded in previous studies, Chrysopetalum occidentale and Paleanotus chrysolepis. In this study 311 specimens were revised, and nine species, belonging to six genera were found. Eight of these species are new records from the southern Mexican Pacific coast: Arichlidon watsonae n. sp., Bhawania cf. goodei, Chrysopetalum elegantoides, C. maculata, Hyalopale sp., Paleaequor psamathe, Paleanotus bellis and P. purpurea. A new species is also described, Arichlidon watsonae n. sp., which is characterized by the curved tips blades of the falcigers and their small and ovoid palps. Additionally, the genera Arichlidon and Hyalopale are recorded by first time from the Tropical Eastern Pacific.

A taxonomic analysis of diatoms found on Phyllodictyon pulcherrimum yielded a total of 244 diatom taxa (all illustrated) within 27 orders, 45 families, and 86 genera. The Taxa were briefly documented in a list including identification references and morphometric data. Thirty-eight of the taxa identified at the species and infraspecific levels represent new records for the coasts of Mexico. Seven were recorded for the first time on the American continent: Auricula flabelliformis, A. pulchra, Campylodiscus scalaris, Coscinodiscus mesoleius, Dimeregramma fulvum, Navicula palpebralis var. angulosa, and Seminavis barbarae, and one, Nitzschia fusiformis, for the Pacific Ocean. This is the second record of the chlorophyte P. pulcherrimum in the north Pacific and the third for Mexican waters. The results confirm that surveying rare macroalgae species as hosts for epiphytic diatoms provides opportunities to seek new records of diatom taxa, or even new taxa, in regions around the world.

The Pacific coast of Colombia has been poorly explored, and its fauna is one of the least known in the tropical eastern Pacific. Although knowledge of the decapod fauna from this coast has recently increased, the information is scattered in numerous sources. A review of the literature showed that 378 decapods have been reported from this coast, including the islands of Gorgona and Malpelo. The numbers of species are distributed as follows; Dendrobranchiata, 18; Caridea,79; Thalassinidea, 13; Palinura, 6; Anomura, 61; and Brachyura, 201 .Twenty-seven species are known exclusively from the Colombian coast, three of which are endemic to the islands of Malpelo or Gorgona. A list of nominal species is presented, including information on distribution, important references, and synonyms under which the taxa have been reported for this coast. A summary of the history of explorations of the Pacific coast of Colombia as it relates to decapods, is presented. Zoogeographic affinities are briefly discussed for the marine species based on published distributions. Affinities are greatest with the Gulf of California (51.8%), followed by the Galápagos (28.6%), the Indo-Pacific (8.8%), and the Caribbean- Atlantic (7.7%).

Squat Lobsters

Seven species of chirostyloidean squat lobsters are reported from the Galapagos Rift zone and Galapagos platform: Eumunida subsolanus n. sp. (Eumunididae), Heteroptychus galapagos n. sp., H. nautilus n. sp. (Chirostylidae), Uroptychus bellus Faxon, 1893, U. compressus n. sp., U. occidentalis Faxon, 1893 (Chirostylidae), and Sternostylus defensus (Benedict, 1902) (Sternostylidae). All new species are described and illustrated, and the two species previously known from the Galapagos Islands, Uroptychus bellus and U. occidentalis, are re-illustrated from respective lectotypes, herein designated, since both original descriptions were only brief. Both the species of Heteroptychus and Eumunida subsolanus are the first representatives of their respective genera in the eastern Pacific and the latter is also the first record for the family Eumunididae in the region.

The first comprehensive list of 318 coastal fish species recorded from the Islas Marías Archipelago, Mexico, was compiled from recent fieldwork, archival museum collections, and literature references. The jacks (Carangidae, 18 species) and the labrisomid blennies (Labrisomidae, 16) were the most speciose families. Most recorded species occur throughout the tropical eastern Pacific (160 species), while a significant proportion have wider ranges in the eastern Pacific (39), eastern Pacific and Indo-Pacific (39), eastern Pacific and Atlantic (3), or are circumtropical (39) in distribution. Three species occur in the Northeast Pacific, twenty-five are endemic to the Pacific coasts of Mexico, five are endemic to the Gulf of California, and three are endemic to Islas Marías. Cephalopholis panamensis (Epinephelidae), Epinephelus labriformis (Epinephelidae), Mulloidichthys dentatus (Mullidae), Stegastes flavilatus (Pomacentridae), Acanthurus xanthopterus (Acanthuridae), Pseudobalistes naufragium (Tetraodontidae), and Sufflamen verres (Tetraodontidae) were the dominant conspicuous species observed during underwater surveys in 2010. The absence or low abundance of commercially valuable shark, ray, and grouper species throughout the archipelago is discussed.

Thirteen centiped species and one symphylan are reported from the Galápagos Islands. Hanseniella caldaria (Hansen) is the first symphylan reported from the Galápagos Islands. Among the centipeds, Hemiscolopendra galapagosa Chamberlin is a new synonym of Scolopendra galapagoensis Bollman and should be deleted from the Galápagos list. Cormocephalus andinus Kraepelin, its probable junior synonym C. carolus Chamberlin, and Nannopodellus purpurascens Chamberlin, previously reported from the Galápagos Islands, were not in any collections made from 1974 to the present and may be extinct on the islands. Lamyctes coeculus (Brölemann), Lamyctes fulvicornis Meinert, and Newportia monticola Pocock are new records, and first appear in collections made in 1974. Two new species, Pectiniunguis krausi and Pachymerium perdrai, are described. The former had been misidentified previously as Pectiniunguis albermarlensis Chamberlin. While Pectiniunguis albemarlensis and Scolopendra galapagoensis may be Galápagos endemics, lack of knowledge about the centiped fauna of source areas precludes definitive statements.
