First record of glycera guatemalensis and G. sphyrabrancha (Annelida: Glyceridae) from Western México por De León González, Jesús Ángel, Tovar Hernández, María Ana, Torres Manríquez, Iliana, García Garza, María Elena

“…Methods: An analysis of the glycerides of the Pacific coast of Mexico was carried out, finding two species that were collected, one of shrimp trawl at a depth of 18 meters off Puertecitos, Baja California, as well as by manual sampling in the intertidal zone of Concepción Bay, Baja California Sur in the Gulf of California. For their taxonomic determination, morphological characters of greater relevance for their identification were examined, such as jaws, aileron shape, parapodia, chaetae, and the type of pharyngeal papillae. …”

A new parrot taxon from the Yucatán Peninsula, Mexico—its position within genus Amazona based on morphology and molecular phylogeny por Silva, Tony, Guzmán, Antonio, Urantówka, Adam D., Mackiewicz, Paweł

“…However, taken together tree topology tests and morphometric analyses, we can conclude that the new parrot represents a recently evolving species, whose taxonomic status should be further confirmed. This lineage diverged from its closest relative about 120,000 years ago and was subjected to accelerated morphological and behavioral changes like some other representatives of the genus Amazona. …”
