Zoosystema 39 (4): 501-598. https://doi.org/10.5252/z2017n4a5 ABSTRACT 313 nominal species of monogenean parasites of aquatic vertebrates occurring in Mexico are included in this checklist; in addition, records of 54 undetermined taxa are also listed. All the monogeneans registered are associated with 363 vertebrate host taxa, and distributed in 498 localities pertaining to 29 of the 32 states of the Mexican Republic. The checklist contains updated information on their hosts, habitat, and distributional records. We revise the species list according to current schemes of KEY WORDS classification for the group. The checklist also included the published records in the last 11 years, Platyhelminthes, Mexico, since the latest list was made in 2006. We also included taxon mentioned in thesis and informal distribution, literature. As a result of our review, numerous records presented in the list published in 2006 were Actinopterygii, modified since inaccuracies and incomplete data were identified. Even though the inventory of the Elasmobranchii, Anura, monogenean fauna occurring in Mexican vertebrates is far from complete, the data contained in our Testudines. checklist depict the actual knowledge about this group of flatworms in Mexico.

  • Two New Species of Sea Catfish Named
    Media only: Elisabeth King (507) 212-8216; [email protected] June 30, 2017 Sean Mattson (507) 212-8290; [email protected] Media website: http://www.stri.si.edu/english/about_stri/media/press_releases/index.php Two new species of sea catfish named A group of scientists from Panama, Colombia, Brazil and Puerto Rico have described two new species of sea catfish in the genus Ariopsis, in a report published in the journal Zootaxa. Based on a specimen from Casaya Island in Panama’s Las Perlas archipelago, they named the first new species, Jimenez’s Sea Catfish, Ariopsis jimenzi for Máximo Jiménez Acosta, a zooarchaeology technician in archaeologist Richard Cooke’s lab at the Smithsonian Tropical Research Institute. Jiménez drew attention to the possible existence of a new species based on his examination of bone characteristics in specimens formerly originally believed to be A. seemanni, or the Colombian shark catfish. His observation that the bones belonged to a new species was immediately confirmed by molecular analysis. The second new species was named the New Granada sea catfish, Ariopsis canteri, for Diego Canter Ríos (1984-2007), a young and talented Colombian ichthyologist who died in a traffic accident near Santa Marta, Colombia along with three other biology undergraduates. He collected the data on the new species and also worked on this group of catfish for part of his bachelor’s thesis in marine biology. The zoologists in the team — Alexandre Marceniuk from Brazil’s Museu Paraense Emílio Goeldi; Arturo Acero of the Universidad Nacional de Colombia, and Ricardo Betancur of the University of Puerto Rico — constructed a family tree showing how the eight different species in the genus Ariopsis are related.

El estudio de más de 35,000 restos muestra que se usaron 391 individuos de 63 especies y 35 familias. Siete especies fueron particularmen- te importantes por la cantidad de individuos y su frecuencia de uso, aunque el único atributo en común a las 11 ofrendas, es el pez sierra (Pristis). Sólo fueron ofrendados peces marinos, predominando las formas del Atlántico. La mayoría de los peces fueron depositados con una preparación taxidérmica para eliminar la columna vertebral. Las ofrendas colocadas en el relleno constructivo fueron marcadamente menos diversas respecto de las otras ofrendas colocadas en cistas. Aunque se pudieron relacionar algunas especies mencionadas por Sahagún con las ofren- dadas, las fuentes etnohistóricas proporcionan poca información de los peces y su uso, de ahí la importancia de un apropiado rescate y estudio de los restos de peces como fuente primaria y casi exclusiva de las relaciones entre el hombre mesoamericano y este recurso.

LEOPOLDINA AGUIRRE-MACEDO Centro de Investigación y Estudios Avanzados del Instituto Politécnico Nacional (CINVESTAV-IPN) Unidad Mérida, Carretera Anti- gua a Progreso Km. 6, A.P. 73 Cordemex, 97310 Mérida, Yucatán, México. E-mail: [email protected] Abstract A total of 33 species of metazoan parasites were identified (31 helminth and 2 crustaceans) from 10 species of fish (n = 1,030) collected from Coyuca Lagoon, Guerrero, Mexico, between May 2001 and February 2003. Digeneans (7 adults and 11 larvae) dominated the parasite fauna. The most widespread species of parasite were: Digenea- Pseudoacanthos- tomum panamense, Diplostomum (Austrodiplostomum) compactum, Clinostomum complanatum; Nematoda- Contracae- cum sp.; Branchiura- Argulus sp.; and Copepoda- Ergasilus sp. Species composition of the parasite fauna exhibited a clear freshwater influence; 57.5% (19/33) of the identified species have a freshwater distribution. This is the first survey of parasites of fish from this location and all reported species are new geographical host records for Coyuca Lagoon, Guerrero, Mexico. Key words: Digenea, Nematoda, Crustacea, fish, Coyuca Lagoon, Guerrero, Mexico Introduction Coyuca Lagoon is one of the most important aquatic resources in the state of Guerrero, Mexico, because of its size (28.5 Km2) and fish production (Violante-González 2006). Located 35 km northwest of Acapulco, this lagoon is predominantly oligohaline (1.5 to 5 ppm) during most of the year, but has a marine influence during the rainy season when temporary connections open between it and the Pacific Ocean.

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.
