Global arthropod beta-diversity is spatially and temporally structured by latitude.

Global biodiversity gradients are generally expected to reflect greater species replacement closer to the equator. However, empirical validation of global biodiversity gradients largely relies on vertebrates, plants, and other less diverse taxa. Here we assess the temporal and spatial dynamics of global arthropod biodiversity dynamics using a beta-diversity framework.

Diversity of an Odonata assemblage from a tropical dry forest in San Buenaventura, Jalisco, Mexico (Insecta, Odonata).

Background: The patterns of richness, diversity, and abundance of an odonate assemblage from San Buenaventura, Jalisco are presented here. A total of 1087 specimens from seven families, 35 genera and 66 species were obtained through monthly samplings of five days each during a period of one year. Libellulidae was the most diverse family (28 species), followed by Coenagrionidae (21), Gomphidae (7), Aeshnidae (6), Calopterygidae (2), Lestidae (1) and Platystictidae (1).

New species and records in Phrynidius Lacordaire (Coleoptera, Cerambycidae, Lamiinae).

Phrynidius Lacordaire, 1869, a genus of Mesoamerican distribution, is a group whose original taxonomic knowledge was generally limited, mainly due to the original descriptions not allowing for the adequate determination of its species. Recently, this knowledge was increased with the description of new species and the publication of a key to separate them. However, this knowledge is still incomplete, and there remain undescribed species deposited in different entomological collections.

New species of Hyperplatys Haldeman, 1847 and Urgleptes Dillon, 1956 (Coleoptera: Cerambycidae) from Mexico.

Two new species of Acanthocinini (Lamiinae) from Mexico are described: Hyperplatys mexicanus sp. nov. from the state of Morelos; and Urgleptes martini sp.

Patterns of richness, diversity and abundance of an odonate assemblage from a tropical dry forest in the Santiago Dominguillo Region, Oaxaca, México (Insecta: Odonata).

A study on the patterns of richness, diversity and abundance of the Odonata from Santiago Dominguillo, Oaxaca is presented here. A total of 1601 specimens from six families, 26 genera and 50 species were obtained through monthly samplings of five days each. Libellulidae was the most diverse family (21 species), followed by Coenagrionidae (19), Gomphidae (4) and Calopterygidae (3).

Four new species of Lacordaire (Coleoptera, Cerambycidae, Lamiinae) from Mexico with an identification key for the genus.

Since the description of its eight species, the Mesoamerican genus Lacordaire (Cerambycidae, Lamiinae, Apomecynini) has not been comprehensively studied, with only a few distributional records published in recent years. In this work, four new species of are described from Chiapas, Mexico: from the municipality of Escuintla, from San Cristobal, from Trinitaria, and from Jaltenango. An updated taxonomic key and illustrations of the new species are also provided.

A new species, and a new distribution record for the genus Sympleurotis Bates, 1881 (Coleoptera, Cerambycidae, Lamiinae) from Mexico.

A new species of the genus Sympleurotis Bates from Jalisco, Mexico is described and illustrated. Details of a new state record of Sympleurotis rudis Bates, 1881 from Chiapas, Mexico is also included.

Two new species of the genus (Coleoptera: Cerambycidae) from Mexico and Guatemala.

Two new species of the genus Nemognathomimus Chemsak & Linsley are described and illustrated, Nemognathomimus wappesi sp. nov. from the Mexican states of Chiapas and Oaxaca and from Guatemala, and N.
