Squat Lobsters

Seven species of squat lobsters were collected during the TALUD XIV cruise in the Gulf of California, Mexico. Gastrop-tychus perarmatus (Haig, 1968) was collected for the second time since it was described and represents a first record ofthe genus in the tropical eastern Pacific. Its association with gorgonians is also noted from color pictures taken during adeep-water dive in another cruise in the area. Janetogalathea californiensis (Benedict, 1902) was captured in four sam-pling stations, in the same area where it has been previously reported. Three species of Munida Leach, 1820 were collected(M. bapensis Hendrickx, 2000, M. mexicana Benedict, 1902, and M. tenella Benedict, 1902). Records of M. bapensis ofthis cruise combined with additional captures of this species in 2007 in the same area indicate that it is the most abundantdeep-water species of squat lobster in the northern part of the central Gulf of California. Among the species of Munida,M. tenella was second in abundance and included specimens much larger than previously known. The single record forM. mexicana fits within the currently known depth and geographical ranges. Only one species of Munidopsis Whiteaves,1874 (M. depressa Faxon, 1892) was collected, in one of the deeper sampling stations visited during the cruise and itsnorthernmost distribution limit within the Gulf of California is increased by ca two degrees of latitude. The seventh speciescollected during this survey, Pleuroncodes planipes Stimpson, 1860, is a common inhabitant of the California Current and the Gulf of California.

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%).

We report the occurrence of a major corallivore, the Crown-of-thorns Starfish Acanthaster planci, on the coral reefs of Gorgona Island, Tropical Eastern Pacific. Three individuals were sighted on opposite sides of the island, where they fed on small coral colonies of Pavona varians and Pocillopora damicornis. These sightings are noteworthy in light of reports that have demonstrated that the geographic distribution of A. planci is gradually increasing in the equatorial eastern Pacific, particularly south of the Gulf of Chiriquí (Panama) where it was previously absent.

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.

A first checklist of conspicuous reef fishes observed at 15 sites in the vicinity of Bahía de los Ángeles from 2008 to 2010 is presented. A total of 70 species representing 31 families were observed. Species composition was similar to well studied regions in the southern Gulf of California, in that most species had distributions that span the Tropical Eastern Pacific but species endemic to Mexico or the Gulf of California ranked highest in relative abundance, frequency of occurrence, and mean density. Several species with temperate geographic distributions were more abundant and frequent than on reefs in the southern Gulf. Large-bodied, predatory species such as sharks and the Gulf Grouper, Mycteroperca jordani, were rare or absent.

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.

Unusual Combination

During a recreational fishing trip on May 2017 to Isla Montuosa, Pacific coast of Panama (7.467472, -82.266556; 30 m depth), a specimen belonging to the genus Caranx was captured. The specimen showed an unusual combination of external characters, intermediate among the species known to occur in the Tropical Eastern Pacific (TEP), which caught the attention of the fishermen. A detailed analysis involving traditional morphology and molecular techniques revealed that the specimen corresponds to a hybrid of the species C. melampygus and C. sexfasciatus. This represents, to the best of our knowledge, the first confirmed record of hybridization within the genus and family in the TEP and the second record for the entire Pacific Ocean.

AbstractSe describe Acasta newmani n. sp. del Golfo de California. Esta es la primera cita de Acasta en el Pacofico oriental. Se discuten las hip otesis sobre la correlacion entre morfologoa cirral y los metodos de alimentacion y especificidad de huespedes. Las similitudes, entre A. newmani y A. cyathus Darwin, 1854 indican que son un ejemplo del patron comun entre especies hermanas a ambos lados del istmo de Panama, en el Caribe y Pacofico oriental tropical. Se incluye una clave de las siete especies americanas de cirropedos que viven en esponjas, indicando la especie huesped y sus distribuciones. El rango de distribucion de Membranobalanus nebrias (Zullo & Beach, 1973) se extiende desde las islas Gal apagos hasta el Golfo de California. Acasta newmani n. sp. from the Gulf of California, Mexico is described. This is the first report of Acasta from the eastern Pacific. Hypotheses are discussed concerning the correlation of cirral morphology with feeding methods and host specificity. The similarities between A. newmani and Acasta cyathus Darwin, 1854 indicate that they are examples of the common pattern of trans-isthmian sibling taxa in the Caribbean and eastern tropical Pacific. A key to the seven sponge-inhabiting barnacle species of the Americas is presented with citations noting their host sponge species and known ranges in the Americas. The range of Membranobalanus nebrias (Zullo & Beach, 1973) is extended from the Galapagos Islands to the Gulf of California.
