The number of species per family were: Curculionidae (89), Apionidae (29), Dryophthoridae (11), Rhynchitidae (6), Attelabidae (5), y Erirhinidae (1). The genera with the greatest diversity of species were Trichapion (14), Pandeleteius (11), Anthonomus (11), Sibinia (9), and both Rhyssomatus y Ophryastes with five species. The biogeographic distributions indicated that the majority of the species were restricted to "Mega-Mexico 3" sensu Rzedowski ; a region from the north of Nicaragua to the southwestern United States. The similarities of the present list of species with that of previous reports from the state of Guanajuato and El Cielo, Tamauliapas were low (Jaccard{\textquoteright}s Index =0.159 y 0.090, respectively). These comparisons, together with a calculation of the expected number of species of Curculionoidea of the state, (using the proportion of total number of identified species of plants of Mexico with the respective total of Curculionoidea), indicated that the present list represents less than one half of the total number of species for the state.}, isbn = {0065-1737}, author = {Jones, Robert W. and Luna-Cozar, Jesus} } @article {13132, title = {Diversity and biogeographic affinities of Apionidae (Coleoptera: Curculionoidea) along an altitudinal gradient in El Cielo Biosphere Reserve of northeastern Mexico}, journal = {Revista Mexicana De Biodiversidad}, volume = {83}, number = {1}, year = {2012}, month = {marzo}, pages = {100-109}, abstract = {The attitudinal and temporal distributions of species in the family Apionidae (Coleoptera: Curculionoidea) were studied in El Cielo Biosphere Reserve (ECBR) in the state of Tamaulipas, northeastern Mexico. Species richness, diversity and abundance were recorded along an attitudinal gradient, from 100 to 1 900 m. A total of 571 individuals of 51 species were collected, representing 30\% of the total species of Apionidae recorded for Mexico. Richness estimators (Chao 2) indicated that 75\% of the species present were sampled. Species richness and diversity was greatest in tropical forests. Species geographic distributions were found to fall into 3 categories: mega-Mexico, tropical and temperate. The majority of the species (55.3\%) were restricted to mega-Mexico (southern southwestern US to northern Nicaragua), with fewer species with tropical (27.7\%) and temperate (17.0\%) distributions. Species with tropical distributions had highest diversity and greater overall abundance in low elevations in tropical forests when compared to higher elevation forests (cloud and pine/oak). In contrast, diversity and abundance for species with temperate and mega-Mexican distributions were similar in all forest types. Greater richness and abundance occurred during the dry season (December through May) than the rainy season, suggesting populations of Apionidae were in immature stages during this latter period, with active adults predominating during the dry season, many of which were probably in a non-reproductive physiological state.}, keywords = {Apionidae}, author = {Jones, Robert W. and Nino-Maldonado, Santiago and Luna-Cozar, Jesus} } @article {13133, title = {Insect diversity of tropical montane forests: diversity and spatial distribution of weevils (Coleoptera: Curculionidae) inhabiting leaf litter in southern Mexico}, journal = {Annals of the Entomological Society of America}, volume = {101}, number = {1}, year = {2008}, month = {January}, pages = {128-139}, type = {Article}, abstract = {The abundance, diversity, and spatial distribution of the weevil fauna (Coleoptera: Curculionidae) of leaf litter were compared between primary and successional cloud forests at the Biological Reserve Cerro Huitepec in the highlands of Chiapas, Mexico.

Total weevil densities averaged 8.51 [plus or minus] 9.04 individuals per 0.5 m2 of leaf litter. Estimates of the total number of leaf litter weevils in the reserve were >20 million. Data suggest that even small fragments of cloud forest (10 ha) may maintain viable populations of the more common species of leaf litter weevils for extended periods. However, because of their low powers of dispersion and their high levels of endemism, leaf litter weevils, and presumably other leaf litter insects, are particularly vulnerable to extinction when whole forest fragments are lost or when recent climate changes push cloud forests to higher elevations.}, isbn = {0013-8746}, author = {Jones, Robert W. and Charles W.
