We also propose Photinus cubilguitzi Prez-Hernndez Zaragoza-Caballero nom.

Phylogenetic analysis of the family Megalopodidae (Coleoptera: Chrysomeloidea): better taxon-sampling facilitates detection of new relationships and new taxa.

The systematics of Megalopodidae is not adequately known, in spite of it being a relatively small group of phytophagous beetles. The first phylogenetic analysis of Megalopodidae with a comprehensive generic representation (25 genera of 30 described, 10 subgenera and 77 species) is undertaken. A parsimony analysis under equal and implied weights was carried out based on 147 adult and larval morphological characters.

Revision of the genus LeConte, 1881 (Coleoptera, Phengodidae), with the description of four new species, new geographic records and a new synonymy.

A taxonomic revision of the genus LeConte, 1881 (Coleoptera: Phengodidae) is provided, including new data on geographic ranges of the species. This is the first time this genus has been recorded for Belize and in Honduras. Four new species (, , and ) are described and a new synonymy (, Zaragoza-Caballero, 1991 = Wittmer, 1976) is established.

New species of the genus Cenophengus LeConte 1881 (Coleoptera; Phengodidae) from Mexico and Guatemala.

Six new species of the genus Cenophengus LeConte, 1881 are described. Five of these new species were collected in Mexico, in the states of Hidalgo (Cenophengus mboi sp. nov.

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).

Agathidium mexicanum Hendrichs, 1979: Types rediscovered.

Agathidium mexicanum Hendrichs, 1979: 106 is the single Mexican species of Leiodidae described by a Mexican entomologist: Chemical Engineer Jorge Hendrichs. As an amateur coleopterist he made a beetle collection of 18,400 specimens, adequately labeled by his wife and daughter. Most of the specimens are now in the entomological collection of the Instituto de Biología, UNAM.

Checklist of net-winged beetles (Coleoptera: Lycidae) from Mexico.

A checklist, distribution records, and the updated nomenclature for Mexican Lycidae are presented here. Two subfamilies, 7 tribes, 24 genera, 2 subgenera and 168 valid species of Lycidae (Coleoptera: Elateroidea) taxa were recorded from Mexico, including 111 (66%) endemic species. For each species, synonyms used in Mexico and geographical distribution in Mexican states were provided.

A checklist of the Coleoptera (Insecta) from Morelos, Mexico.

Data from the literature and from specimens preserved at the Colección Nacional de Insectos (CNIN) Instituto de Biología, UNAM were used to compile a checklist of the fauna of Coleoptera of the state of Morelos, México. A sum of 70 families, 167 subfamilies, 361 tribes, 1,022 genera, and 2,606 species are recorded; from this 24 species are new records for Morelos. The State of Morelos ranks fourth in Coleoptera species richness for Mexico, following Veracruz (3,176 spp.

Comparative morphology of the spermatheca in Megalopodidae (Coleoptera, Chrysomeloidea).

The spermatheca is an organ that stores and maintains viability of sperm until fertilization. It has an important role in copulation and oviposition, and it is highly informative in species delimitation. Here, we present a comparative study of the spermathecal morphology in the coleopteran family Megalopodidae.

Revision of Ogdoecosta Spaeth 1909 with description of Ogdoecosta paraflavomaculata López-Pérez, sp. nov. (Coleoptera: Chrysomelidae: Cassidinae: Mesomphaliini).

The tortoise beetle genus Ogdoecosta Spaeth 1909 is revised and an illustrated key to 12 species is provided, based on a morphological analysis of all species. All the known species are redescribed and one new species, Ogdoecosta paraflavomaculata López-Pérez sp. nov.

A preliminary study on the phylogeny of the family Phengodidae (Insecta: Coleoptera).

A morphology-based phylogenetic analysis of the family Phengodidae (Coleoptera) is given. Thirty-six terminals, six genera and 60 morphological characters are included. To test the monophyly of phengodid subfamilies the terminals that belong to superfamily Elateroidea Drilocephalus Pic (Dascillidae), Pterotus LeConte (incertae sedis), Vesperelater Costa (Elateridae), Photinus Laporte (Lampyridae), Pseudotelegeusis Wittmer and Telegeusis Horn (Telegeusidae) are used as outgroups, with the remaining 30 terminals corresponding to 26 specific and four generic levels.

A preliminary phylogenetic analysis of the New World Helopini (Coleoptera, Tenebrionidae, Tenebrioninae) indicates the need for profound rearrangements of the classification.

Helopini is a diverse tribe in the subfamily Tenebrioninae with a worldwide distribution. The New World helopine species have not been reviewed recently and several doubts emerge regarding their generic assignment as well as the naturalness of the tribe and subordinate taxa. To assess these questions, a preliminary cladistic analysis was conducted with emphasis on sampling the genera distributed in the New World, but including representatives from other regions.
