We examine herein the spatial changes in species distribution and explore the overlapping of species' ranges towards the centre of the Gulf, to test whether the mid-domain effect (MDE) could explain an expected middomain peak in species richness. The faunal composition and the latitudinal range of 244 species of polychaetes recorded along the continental shelf of the Gulf of California were analysed in latitude bands of 1°. The species composition changes around the Gulf's archipelago (*29°N), and the highest values of species richness are found at the 25°(197 species) and 26°(193 species) of latitude. Although the species richness pattern could be described by a parabolic shape, the regional trend was not strongly consistent with the peak of diversity at 27°N (176-191 species) predicted by the mid-domain effect: the random sorting of species' ranges within spatial domain does not explain satisfactorily the geographical patterns of diversity. Nevertheless, a partial contribution of MDE to these natural patterns of diversity could be detected, and the increase in species richness towards middle latitudes was basically determined by species with distribution ranges larger than 6°. The low level of significance between the empirical species richness pattern and the middomain model prediction for polychaetes in the Gulf does not restrict their use as a model for exploring the randomness of the diversity patterns.

This new species is characterized by the presence of a prostomial palpode, only notopodia in the first chaetiger, hooded hooks in neuropodia of chaetiger 11, and its distinct methyl green staining pattern consisting of: chaetigers 1-4 slightly stained, chaetigers 5-10 with green bands encircling the segments, and a darker, solid, green band encircling the body in chaetigers 11-12. It is mainly distributed in the central Gulf of California in fine sand bottoms (62-96%) at 32-106.4 m depth, tolerating a wide range of temperature (13.2-17.59 °C), dissolved oxygen (0.8-4.93 ml/L), and organic carbon (3.0-7.2%). The type material and original descriptions of Notomastus species with hooks in thoracic chaetigers were examined; an identification key and tables with morphological distinctive characteristics, methyl green staining patterns, and geographic distribution of these close species are provided.

The northern limit of the distribution of S. superus is expanded from Panama to Guerrero, Mexico. We also consider that Synalpheus fritzmuelleriCoutiere, 1909 is most probably not an amphi-American species. Its former status as such was due to taxonomic misinterpretations by Hernandez Aguilera et al. (1986) and probably by Coutiere (1909) himself, although his questionable record of a single specimen of S. fritzmuelleri from the Gulf of California could not be verified, because the specimen could not be located and may be lost.

Objective: To examine the taxonomic composition of the Eunicida and Amphinomida associated to dead coral substrates from this coral reef atoll, a Biosphere Reserve located in the southern Mexican Caribbean. Methods: In April 2008, dead coral fragments of the genus Porites were manually collected by SCUBA diving at eight stations between 4-16.2 m depth. Results: A total of 714 individuals belonging to 17 genera and 48 species of the families Amphinomidae, Dorvilleidae, Eunicidae, Lumbrineridae, Oenonidae and Onuphidae were identified. Eunicidae was clearly the more diverse (29 species; 60.4 %) and abundant family (479 individuals; 67.1 %), while the Oenonidae and Onuphidae were represented by only one individual-species each. Thirty-eight species (79.2 %) were new records for Chinchorro Bank, of which 23 species (47.9 %) were newly reported for the Western Caribbean ecoregion. Conclusions: The polychaete fauna recorded showed that the Chinchorro Bank reef is a species-rich habitat that deserves further study; the 48 species from six families identified were similar or even greater than the number of species reported from dead coral environments of other Caribbean Sea regions.

It was found in dead coral rocks at depths of 2.2 m and can be distinguished from its congeners by having simple filaments branchiae from chaetigers 19–24, as well as bi- and tridentate pseudocompound falcigers and large median simple tridentate hooded hooks in the first four chaetigers. Including M. bidentata sp. nov., the genus Mooreonuphis includes 19 species, which have been exclusively collected on the American coasts, mainly in tropical and temperate waters. From the Caribbean Sea, six species have been recorded. Of these, M. bidentata sp. nov, M. cirrata, M. dangrigae and M. intermedia are the only species having their locus typicus in this tropical region. A taxonomic key is presented for all the species of Mooreonuphis recorded from both sides of the American seas.

A total of 56 species belonging to 39 genera and 22 families were collected from eight stations sampled during the spring of 2006 at 31 to 208 m depth. Onuphidae (14 species), Paraonidae (7 species) and Spionidae (6 species) were the best represented families. The highest number of species and individuals (mean= 13 species station-1 ; 76.7 ind. 0.1 m-2) was found in stations located in the Gulf shelf while inside of La Paz Bay, the fauna was less abundant and diverse (mean= 9 species station-1 ; 47.0 ind. 0.1 m-2). Differences in species composition defined two main faunal groups, which were linked by their spatial distribution: assemblage Aricidea (Acmira) simplex-Aglaophamus verrilli inside the Bay, and assembage Paraexogone molesta-Cirrophorus furcatus-Prionospio dubia in the Gulf shelf. The composition and structure of the fauna was mainly associated with the sediment type (Rho= 0.48; p= 0.06): muddy habitats inside the bay and sandy bottoms in the Gulf. Only 11 out of the 39 identified genera (28.2%) had more than two species, and only seven of the 23 families (30.4%) had two or more species. This taxonomic heterogeneity caused a wide variability in the "average taxonomic distance" of every pair of individuals at each station (64.69 to 89.58). Therefore, the distribution patterns of the taxonomic diversity values between the sites inside La Paz Bay (mean= 79.45) and those found outside, in the Gulf (mean= 79.77), were similar.

Thirty seven stations were sampled in the former and 30 in the latter. A total of 5153 organisms in 12 genera and 27 species were determined. The spionids were better represented in the central-eastern region in the Gulf of California and to the west of Salina Cruz, in the Gulf of Tehuantepec, in depths ranging from 60 to 100 m. In both areas, the dominant species was Paraprionospio pinnata , a cosmopolitan species, distributed practically along the entire study area and representing 75% and 86% of the organisms found in the Gulfs of California and Tehuantepec respectively. The spionids, basically represented by species with Amphiamerican or extended geographic distribution, represent 64% of the organisms from both gulfs.

Twelve stations at depths from 30 to 106 m were selected as representative of the region. A total of 2510 polychaetes belonging to 33 families and 152 species were identified. The Spionidae (15 species), Lumbrineridae (11 species), Onuphidae and Cirratulidae (10 species each) were the families with the highest number of species, although only the spionids (96.29 ind./0.1 m 2) were found in considerable densities. Distribution of the assemblages clearly reflected the influence of sediment type. The polychaete fauna was divided in two main groups: those distributed in sandy sediments and those found in sediments with higher mud content. The sandy assemblages were represented by the Phyllodoce sp. 1 group, distributed in the outer continental shelf to the south of the study area; the Aglaophamus verrilli, Chone sp. 1 and Spiophanes duplex group, which was found on the inner and middle shelf; and by Prionospio (P.) ehlersi, Chaetozone setosa, Monticellina dorsobrachialis and Leiocapitella glabra, a group located in the deeper zones of the northern coasts. The assemblages associated with muddy-sand bottoms were mainly characterized by Paranaitis sp. 1, found on the eastern coasts, and by the fauna distributed in the western region, where Scoloplos texana was the most common species.

Their morphological homogeneity and the reduced number of external characteristics make it difficult to separate the genera taxonomically (Oug, 2002). In 1865 Kinberg established the Genus Ninoe to include the eunicemorphs with no prostomial appendices or tentacular cirri and with branchiae arising from the postchaetal lobes in anterior parapodia. Initially, he included three species from Chile and Brazil: N. chilensis, N. brasiliensis and N. oculata. Much later, Fauchald (1970) emended the genus to include all lumbrinerids with branchial

It is thought that, unlike terrestrial environments, animals are not involved in pollination in the sea. The male flowers of the tropical marine angiosperm Thalassia testudinum open-up and release pollen in mucilage at night when invertebrate fauna is active. Here we present experimental evidence that, in the absence of water-flow, these invertebrates visit the flowers, carry and transfer mucilage mass with embedded pollen from the male flowers to the stigmas of the female flowers. Pollen tubes are formed on the stigmas, indicating that pollination is successful. Thus, T. testudinum has mixed abiotic-biotic pollination. We propose a zoobenthophilous pollination syndrome (pollen transfer in the benthic zone by invertebrate animals) which shares many characteristics with hydrophily, but flowers are expected to open-up during the night.

This proceedings volume includes a brief summary of workshop discussions and field events as well as a compilation of selected research papers presented by an international group of 16 scientists from 12 nations in attendance at the ISBS2. Herein, we highlight molecular, developmental, morphological, ecological, and biogeographic diversity of adult and larval sipunculans. In addition, we introduce several of the outstanding research challenges associated with resolving sipunculan interrelationships, establishing standard sets of taxonomic characters, refining methods for identification of cryptic species, reconstructing an evolutionary framework of developmental life history patterns, and addressing implications of recent phylogenetic and phylogenomic hypotheses that have relocated the ancient radiation of unsegmented sipunculan body plans within the predominantly segmented Annelida. Collectively, although we represent a small group of sipunculan biologists (of whom a matching number did not attend the ISBS2), we hope this volume will not only draw attention to an intriguing and notably understudied clade of marine worms but also attract new researchers to help us promote them as valuable experimental models and to include them among broader interdisciplinary efforts to better understand the biological diversity of marine invertebrate animals worldwide.

The most common trichobranchids in shallow water in Belize and the Mexican shallow-water lagoons along the Gulf of Mexico belong to a species group which also includes Terebellides klemani Kinberg, 1867 and T. anguicomus Müller, 1858. Terebellides klemani has been considered a synonym of T. anguicomus (see Hessle, 1917). After examining specimens from Belize and closely similar specimens from Mexico, the types of T. klemani and specimens collected near the type areas of both previously named species, we believe that we can recognize a series of similar, but distinct, species all of which would have been subsumed under Hessle's concept of T. anguicomus. Our study parallels the analysis of the "cosmopolitan species" T. stroemi Sars, 1835 pubHshed by Williams (1984). Williams used several characters rarely noted in descriptions of trichobranchids to subdivide Terebellides stroemi s. 1.; our observations generally support her conclusions about the importance of characters not previously used to delimit species. Williams did examine specimens from Central America and Northern South America, but was not able to assign them to species other than to note that they did not belong in the species-complex she was analyzing. Her specimens from the region of interest in this study appear to be closely similar to T. klemani and to other species described in this study.

These organisms were collected in the Cenote Aerolito (Cozumel Island, on the Caribbean coast of Quintana Roo) during three sampling events from February 2006 to April 2008, among algae, roots of mangroves, and in karst sediments. A total of 1518 specimens belonging to five families (Paraonidae, Capitellidae, Nereididae, Dorvilleidae, and Syllidae), ten genera, and eleven species were collected. In the cave system, two specimens of the amphinomid Hermodice carunculata were found. This cenote and its biota are now in danger of disappearing because of a marina construction project in its western shore.

It is the third species recorded in Mexico and the second species of Hyalella found in the Aktun-Ha sinkhole. It can be distinguished from its closest species, Hyalella azteca from Veracruz, by the shape of the palp of maxilla 1, the number of setae in the posterior margin of the basis, the relative palm length and the truncate process of gnathopod 2 in males, the number of setae in the lobe of the basis of pereopod 7, and the shape and setation of the telson. Those characters have been found to be useful for species distinction in the complex by González and Watling (2002). The main differences between Hyalella cenotensis and Hyalella maya n. sp. are: the presence of eyes, the number of articles in the flagellum in antennae 1 and 2, the relative length of antennae to the total body length, the relative length of the rami in uropod 3 to the peduncle length, and the number of setae in the telson.
