How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Bess beetles (Passalidae) are known to maintain biological interactions with a diverse gut symbiotic community, which is far from being well described since these communities from most of the species of Passalidae have not been studied. In order to improve our knowledge of these communities, we describe a new species of Nematoda of the genus Hys...
Bess beetles (Passalidae) display important roles in forestall ecosystems, particularly in energy extraction from dead wood. These organisms maintain complex biological interactions with their gut symbiotic communities, including bacteria, protists, and metazoans. Very little is known about symbionts since most of the species of Passalidae haven't...
A new species of the nematode Triumphalisnema Kloss, 1962 (Oxyuridomorpha), is described from the wood beetle Proculejus hirtus Truqui from the mountain mesophilic forest in Hidalgo State, Mexico. Triumphalisnema zuuei n. sp. is distinguished from the other 4 congeners species by the presence of an expanded cervical ring, well-developed lateral ala...
A total of 61 specimens of the Red-headed Spiny Lizard Sceloporus pyrocephalus Cope (Phrynosomatidae) collected during the breeding season (June/July 2003, 2004 and 2005) from Western Mexico were examined for helminths. The morphological characterization of the helminths found was made through light microscopy and scanning electron microscopy. Nine...
Se documenta la presencia de la sanguijuela introducida Barbronia weberi en el río San Juan, Monterrey, Nuevo León, México, que corresponde al segundo registro de esta especie de agua dulce en el país. La identificación de los ejemplares se realizó con base en caracteres morfológicos y moleculares del gen citocromo c oxidasa, subunidad I.
Two new species of Parapharyngodon collected from the intestine of the Mexican boulder spiny lizard Sceloporus pyrocephalus are described. This study increases to 49 the number of valid species assigned to Parapharyngodon worldwide, 11 of them distributed in Mexico. Males of the two new species share the presence of four pairs of caudal papillae, a...
