Los parásitos se fijaron, preservaron y cuantificaron mediante procedimientos estandarizados. Se colectaron 95 parásitos de siete especies, con una abundancia media total de 0.77. El promedio de la riqueza de especies fue 0.46. Los cuatro parásitos con mayor prevalencia y abundancia media fueron: Choricotyle isaciencis Oliva, González, Rus & Luque, 2009, Corynosoma obtuscens (Lincicome, 1943), Proleptus carvajali Fernández y Villalba, 1985, y Clavella simplex Castro y Baeza, 1985. Los parásitos de I. conceptionis señalan que los tres índices de agregación [Dispersión (ID), Discrepancia de Poulin (D) y Binomial Negativa (k)] mostraron mayormente una distribución agregada. La prevalencia de C. isaciencis estuvo correlacionada con la longitud total del pez hospedero. En relación al kn (factor de condición relativo), no se observó que los peces parasitados con C. obtuscens, C. isaciencis, ectoparásitos y endoparásitos presentasen valores más altos en compara- ción con los peces no parasitados. El índice gonadosomático (IGS) no se relacionó con ninguno de los índices de ecología parasitaria.

Phylogenetic analyses were Fish performed on 97 grunt species based on sequence data collected from seven loci. Divergence time estimation Functional traits indicates that Haemulidae originated during the mid Eocene (54.7–42.3 Ma) but that the major lineages were Morphospace formed during the mid-Oligocene 30–25 Ma. We propose a new classification that reflects the phylogenetic Macroevolution history of grunts. Overall the pattern of morphological and functional diversification in grunts appears to be Zooplanktivore strongly linked with feeding ecology. Feeding traits and the first principal component of body shape strongly separate species that feed in benthic and pelagic habitats. The benthic-to-pelagic axis has been the major axis of ecomorphological diversification in this important group of tropical shoreline fishes, with about 13 transitions between feeding habitats that have had major consequences for head and body morphology.

    A REVIEW OF THE SPARID^ AND RELATED FAMILIES OF PERCH-LIKE FISHES FOUND IN THE WATERS OF JAPAN. By David Starr Jordan and William Francis Thompson, Of Stanford University, California. In the present paper is given a review of the species of fishes belonging to those percomorphoiis famihes alUed to the Sparoid fishes, or fishes related to the tai or porgy of the waters of Japan, which have not been hitherto discussed in these pages by the senior author and his associates. The families of Kuldiidse, Priacanthidse, Theraponidse, Banjosidae, Hsemulidae, Sparidse, Kyphosidse, and Ery- thrichthyidse are thus included. The paper is based on material collected in Japan in 1900 by Pro- fessors Jordan and Snyder and now divided between the United States National Museum and the museum of Stanford University. Most of the cuts are from drawings by Mr. Sekko Shimada. The families here named are adopted provisionally only. The dis- tinctions between Sparidse, Haemulidse, Lutianidae, and their relatives are of doubtful value, while at present no definite boundaries can be assigned to the Serranidse. L Family KUHLIID.^. Body oblong, strongly compressed; scales large, cihated. Lateral line complete, the tubes straight and occupying the half or more of the exposed surface of the scale. Mouth rather large, protractile; maxillary exposed, without supplemental bone; teeth in jaws in villi- form bands; teeth on vomer, palatines, entopterygoids, and ecto- pterygoids; tongue smooth; head partly naked; preorbital and pre- opercle denticulate; opercle with 2 spines. Gill membranes separate; 6 branchiostegals; pseudobranchise large; gill-rakers long and slender. Dorsal fms connected at the base, with X, 9 to 13 rays, the spinous portion longer than the soft.

(Monogenea: Diclidophoridae) Parasitic on Microlepidotus brevipinnis (Osteichthyes: Haemulidae) from Chamela Bay, Jalisco, Mexico RAFAEL LAMOTHE-ARGUMEDO, CLAUDIA ARANDA-CRUZ, AND GERARDO PEREZ-PONCE DE LEON' Laboratorio de Helmintologfa, Institute de Biologfa, Universidad Nacional Autonoma de Mexico, Mexico ABSTRACT: A new species of Choricotyle van Beneden and Hesse, 1863, is described from the gills of the sarangola Microlepidotus brevipinnis (Steindachner) Jordan and Fisher, (Haemulidae), from the Pacific Ocean in Chamela Bay, Jalisco State, Mexico. Between May 1993 and May 1995, 53 specimens of M. brevipinnis were collected and examined for parasites. Choricotyle leonilavezquezae sp. n. is distinct from other species within the genus because of the presence of 2 well-developed horseshoe-shaped oral suckers, the shorter lon- gitudinal axis of the haptor, the presence of 8 spines in the genital atrium, and the distribution of vitellaria that extend to the basal area of the peduncles. KEY WORDS: monogenea, Choricotyle leonilavazquezae sp. n., Microlepidotus brevipinnis, gills, Chamela Bay, Mexico. Twenty species of the genus Choricotyle have and May 1995. Chamela Bay is located on the W coast been reported from marine teleosts belonging to of Mexico (19°30', 19°32' latitude N and 105°06' lon- gitude W).

    Tavera et al. BMC Evolutionary Biology 2012, 12:57 http://www.biomedcentral.com/1471-2148/12/57 RESEARCH ARTICLE Open Access Molecular phylogeny of grunts (Teleostei, Haemulidae), with an emphasis on the ecology, evolution, and speciation history of New World species José Julián Tavera1,2*, Arturo Acero P3, Eduardo F Balart1 and Giacomo Bernardi2 Abstract Background: The fish family Haemulidae is divided in two subfamilies, Haemulinae and Plectorhynchinae (sweetlips), including approximately 17 genera and 145 species. The family has a broad geographic distribution that encompasses contrasting ecological habitats resulting in a unique potential for evolutionary hypotheses testing. In the present work we have examined the phylogenetic relationships of the family using selected representatives of additional Percomorpha based on Bayesian and Maximum likelihood methods by means of three mitochondrial genes. We also developed a phylogenetic hypothesis of the New World species based on five molecular markers (three mitochondrial and two nuclear) as a framework to evaluate the evolutionary history, the ecological diversification and speciation patterns of this group. Results: Mitochondrial genes and different reconstruction methods consistently recovered a monophyletic Haemulidae with the Sillaginidae as its sister clade (although with low support values). Previous studies proposed different relationships that were not recovered in this analysis. We also present a robust molecular phylogeny of Haemulinae based on the combined data of two nuclear and three mitochondrial genes. All topologies support the monophyly of both sub-families (Haemulinae, Plectorhinchinae). The genus Pomadasys was shown to be polyphyletic and Haemulon, Anisotremus, and Plectorhinchus were found to be paraphyletic. Four of seven presumed geminate pairs were indeed found to be sister species, however our data did not support a contemporaneous divergence.

  • (Perciformes: Ephippidae) from the Coastal Zone of Tumbes, Peru
    Community structure of metazoan parasites of the Panama spadefish Parapsettus panamensis (Perciformes: Ephippidae) from the coastal zone of Tumbes, Peru JOHN D. CHERO1, CELSO L. CRUCES1, DAVID MINAYA1, JOSÉ IANNACONE2,3* & GLORIA SÁEZ1 1Laboratorio de Parasitología, Universidad Nacional Federico Villarreal, El Agustino, Lima, Perú. 2Laboratorio de Ecología y Biodiversidad Animal, Universidad Nacional Federico Villarreal, El Agustino, Lima, Perú. 3Laboratorio de Invertebrados, Universidad Ricardo Palma, Santiago de Surco, Lima, Perú. *Corresponding author: [email protected] Abstract Fifty-seven specimens of Parapsettus panamensis (Ephippidae) were collected from the coastal zone of Puerto Pizarro, Tumbes, Peru (45°54'S, 81°05'W) between December 2014 and January 2015. The specimens were necropsied to study their metazoan parasites. All specimens of P. panamensis were parasitized by at least one parasite species. Eleven species of parasites were collected: 2 monogeneans, 3 digeneans, 2 nematodes, and 4 arthropods. The endoparasites represented 87.29%, of the total number of parasite specimens collected. Parapsettus panamensis is a new host record for nine parasites collected. The digenean Aponurus laguncula was the highest prevalent and abundant parasite of P. panamensis. Only the digeneans A. laguncula and Multitestis sp1. showed a positive correlation between the hosts’ total length and abundance of infection. The relative condition factor (Kn) of the host correlated with the abundance of A. lagungula and Caligus haemulonis. Parapsettus panamensis had two pairs of parasite species with significant positive association, 1 pair of ectoparasites and 1 pair of endoparasites. Non-metric multidimensional scaling (NMDS) and the relationship between infra-community composition and explanatory variables (host length and sex) were examined by permutational analysis of variance (PERMANOVA) applied to species abundances which shows high homogeneity among metazoan parasites infra-communities of P.

(September 2019), 6(3): 150-196 Received: May 06, 2019 © 2019 Iranian Society of Ichthyology Accepted: July 04, 2019 P-ISSN: 2383-1561; E-ISSN: 2383-0964 doi: 10.22034/iji.v6i2.408 http://www.ijichthyol.org Research Article An annotated checklist of the fishes of the family Haemulidae (Teleostei: Perciformes) Paolo PARENTI* Department of Earth and Environmental Sciences, University of Milano-Bicocca Piazza della Scienza, 1, 20126 Milano, Italy. *Email: [email protected] Abstract: The present study gives an updated checklist of the species belonging to the family Haemulidae. Information on the status of 402 nominal species, including 131 valid species, 235 synonyms, 20 incertae sedis, 10 nomina nuda, and six non-haemulid species, are given. Original spelling of the names, authorship and date of publication have been checked against the Eschmeyer Catalog of Fishes on line (ECoF) (Fricke et al. 2019). The valid genera and species are listed alphabetically in the two currently recognized subfamilies, together with their synonyms, type information, and distributions. Examination of the original descriptions of previously unplaced species led to identification of senior synonyms and junior synonyms. The senior synonyms are: Dentex diplodon Bowdich, 1825, Lutjanus brasiliensis Bloch & Schneider, 1801, Anthias formosus Bloch, 1792 and Pristipomus brasiliensis Lichtenstein, 1823. They represent available names which are never been used (nomina oblita) and predate the following well established fish names which are here regarded as nomina protecta: Pomadasys perotaei (Cuvier, 1830), Rhonciscus crocro (Cuvier, 1830), Haemulon sciurus (Shaw, 1803) and Brachygenys chrysargyreum (Günther, 1859). Mylacrodon Regan, 1903 is a synonym of Boridia Cuvier, 1830.
