Caldasia , 2007,
Abstract: twenty four passalid beetle species are reported. this study is based on field collections and revision of 167 specimens collected in amazonian area of colombia and deposited in two colombian and one mexican collection. illustrations, taxonomic diagnosis and comments about geographical distribution and taxonomy are included. physiographic and land heterogeneity, as a result of forest transformation, affect the distributional patterns of species. finally, ecological and geographic distributions are commented upon.

Macotulio Hernandez,Robert W. Jones,Pedro Reyes-Castillo
ZooKeys , 2013, DOI: 10.3897/zookeys.260.3989
Abstract: Presently the only keys available for identification of genera of Anthonomini are limited to those of the United States of America and Canada. A dichotomous key is presented to identify all genera of Mexican and Central American Anthonomini. Previous keys do not include the genera Achia, Botanebius, Loncophorus, Loncophorellus and Melexerus. A brief synopsis is given for each genus and photographs of representative species are included.

Revista de Biología Tropical , 2008,
Abstract: mites associated to the coleopteran passalus cognatus (coleoptera:passalidae) from los tuxtlas, veracruz, mexico. there are few records of mites associated with the tropical coleopterans of mexico. we examined 35 passalid beetles (bessbugs) passalus cognatus from los tuxtlas region in veracruz state, mexico. twenty of them had a total of 245 mites (representing eight species, eight genera, eight families and three suborders). the most abundant species were uroobovella californiana wisniewski & hirschmann (35%), euzercon hyatti hunter & rosario (20%), and uropoda sp. (17.5%). the preferred attachment areas were the coxae; followed by the mesosternum and the humeri. each beetle had 1 to 40 mites (average: 12); and we found 1-4 mite species per beetle. rev. biol. trop. 56 (3): 1261-1268. epub 2008 september 30.

Revista de Biología Tropical , 2008,
Abstract: Se revisaron 35 ejemplares de Passalus cognatus Truqui recolectados en Los Tuxtlas, Veracruz, México. En 20 de ellos se encontraron 245 ácaros pertenecientes a ocho especies, ocho géneros, ocho familias y tres subórdenes. Las especies de acáros más abundantes fueron Uroobovella californiana Wisniewski y Hirschmann (35%), Euzercon hyatti Hunter y Rosario (20%) y Uropoda sp. (17.5%). Las zonas de fijación preferidas por los ácaros fueron las coxas; en menor proporción el mesoesternón y los húmeros. Los pasálidos infestados presentaron de 1 a 40 ácaros, con un promedio de 12. El número de especies de ácaros por pasálido infestado fue de 1 a 4. Mites associated to the Coleopteran Passalus cognatus (Coleoptera:Passalidae) from Los Tuxtlas, Veracruz, Mexico.

Acta zoológica mexicana , 2010,
Abstract: rates of insect herbivory (% of leaf area eaten per day) were measured on the radicalis palm (chamaedorea radicalis mart.), during three seasons: early and late rainy season and the middle of the dry season at two different sites: temperate and tropical deciduous forest within the state of tamaulipas, mexico. in addition, some structural plant parameters (height, cover and diameter stem), physical plant parameters (foliar toughness and water content) and chemical plant parameters (nitrogen and phenols content) were measured, these parameters were correlated with timely (punctual) herbivory measurements. results from this study show that the early wet season had the most feeding damage (0.17% per day); whereas, the dry season had the least damage (0.09% per day). the rate of herbivory per day during the middle of the wet season was 0.13%. these values are greater than those commonly reported from such habitats. the highest plants (1.1 times more), but with the least covers corresponded to the tropical deciduous forest. within the tropical semideciduos forest this specie cover 2% of understory, whereas to the temperate forest cover 4%. in addition, nitrogen, phenol, and water content of leaves decreased as the season progressed; whereas, leaf toughness increased. we found leaf toughness during the late rainy season and the dry season to be the most effective repellent to herbivory.
Coadaptación entre los ácaros (Arachnida: Klinckowstroemiidae) y coleópteros Passalidae (Insecta: Coleoptera) Co-adaptation between mites (Arachnida: Klinckowstroemiidae) and Passalidae beteles (Insecta: Coleoptera)

Abstract: Realizamos un análisis de la relación que existe entre los ácaros Klinckowstroemiidae y los coleópteros Passalidae, puesto que los ácaros adultos se recolectaron exclusivamente sobre pasálidos (huéspedes). Asimismo, examinamos 1 150 coleópteros recolectados en siete estados de la República Mexicana, y encontramos 19 especies de ácaros klinckowstroémidos asociados con 168 de ellos, pertenecientes a 28 diferentes especies de 15 géneros distintos. Estos táxones establecen una relación simbiótica llamada foresia. No existe una especificidad entre las especies de ambos grupos, debido a que una especie de pasálido puede tener varios forontes, y una especie de ácaro puede asociarse a pasálidos de diferentes géneros y especies. Un ejemplo es Odontotaenius zodiacus que presentó a siete especies de Klinckowstroemia asociadas, y por otro lado, Klinckowstroemia valdezi se encuentra asociada a cinco especies de pasálidos. Además, dos o hasta tres especies de ácaros se encontraron sobre un coleóptero huésped (synhospitality). La falta de congruencias entre la filogenia de los ácaros con la de los pasálidos nos indica que se está produciendo un proceso de coadaptación por colonización, y que ésta asociación se debe a los recursos que le brindan los pasálidos a los ácaros: transporte, refugio y alimento. Como estos recursos no son específicos para algún huésped los klinckowstroémidos se suben a cualquier especie de pasálido. Co-adaptation between mites (Arachnida: Klinckowstroemiidae) and Passalidae beteles (Insecta: Coleoptera). Mites of the family Klinckowstroemiidae establish an association with beetles of the family Passalidae known as phoresy. In order to obtain information about this association, we analyzed the relationship between mites of the family Klinckowstroemiidae and beetles of the family Passalidae, as adult mites have been exclusively collected from host beetles. We examined 1 150 beetles collected in seven states of the Mexican Republic, and found 19 species of klinckowstroemiid mites associated with 168 passalids, that belong to 28 different species in 15 genera. Host specificity between species of both groups does not exist, as one species of passalid beetle can have several different symbionts; conversely, a given mite species can associate with passalid beetles of different species and even of different genera. This way, Odontotaenius zodiacus has been found associated with mites of seven species of the genus Klinckowstroemia. Besides, Klinckowstroemia valdezi is associated with five species of passalids. Furthermore, two and even three different
