Beetles associated with Atta and Acromyrmex ants (Hymenoptera: Formicidae: Attini)

Attini ants form a monophyletic group restricted to America. Atta and Acromyrmex are distributed from the United States south to South America excluding Chile and some of the West Indies. This paper provides new records in addition to the compilation of published information on the beetles associated with those ant genera, including a checklist. There are records for 411 species of beetles associated with Atta and/or Acromyrmex. They belong to 25 families: Carabidae (14 genera/17 species), Hydrophilidae (3/5), Histeridae (18/61), Ptiliidae (3/7), Scydmaenidae (5/8), Staphylinidae (60/141), Passalidae (3/4), Ochodaeidae (1/3), Ceratocanthidae (1/3), Scarabaeidae (33/111), Elateridae (3/6), Lycidae (1/1), Dermestidae (1/1), Anobiidae (1/1), Nitidulidae (2/3), Monotomidae (1/1), Phalacridae (1/1), Cerylonidae (1/3), Endomychidae (1/1) Colydiidae (1/1), Tenebrionidae (10/17), Anthicidae (1/1), Cerambycidae (1/1), Chrysomelidae (7/9) and Curculionidae (3/4). Glenus aureicollis Wasmann, 1902 (not Wasmann, 1925) is synonymized under Glenus regalis Erichson, 1840. Attini-beetle relationships evolved several times within the Order Coleoptera. Permanent beetles are associated with ant debris and/or in fungus chamber; however there is no evidence of direct interactions with the hosts. Most species are associated either with Atta or Acromyrmex, but there are a few species recorded from both genera. Based on the phylogeny of the ants, Attini-beetle relationships are recent ecological interactions, but those with Acromyrmex are older than the ones observed with Atta

New state records for coleoptera in Northern Mexico

Is the apparent rarity of Liatongus monstrosus (Bates) (Coleoptera: Scarabaeidae) real or an artifact of collecting?

Liatongus monstrosus (Bates), previously considered as a rare or even an extinct species, was recently collected from localities in Jalisco State, Mexico. The information provided in this paper increases the previously known distribution and also the importance to develop strategies to preserve it and to determine the current state of this threatened species

A new species of Phanolinus sharp (Coleoptera: Staphylinidae) with a key and comments for Mexican species

Phanolinus elisae, n. sp., from México is described. A key and distribution data for all four Mexican species of Phanolinus are provided. A lectotype and paralectotype are designated for P. speciosus Sharp, 1884

Notes on three adventive species of Coleoptera (Hydrophilidae and Scarabaeidae) from Baja California, with additional data from other Mexican states

Three adventive Coleoptera species are recorded from Baja California, México: Sphaeridium scarabaeoides (Linnaeus), Onthophagus taurus (Schreber) and Aphodius fimetarius (Linnaeus). Sphaeridium scarabaeoides was previously recorded in México City based on specimens collected in 1974, Tepotzotlán, State of México, in 1976 and in Altotonga, Veracruz in 1979. Additional data are provided from specimens collected in Durango, Hidalgo, Jalisco and, Veracruz. Onthophagus taurus is recorded for the first time from México, whereas A. fimetarius are recorded for the first time from Baja California. Distribution maps and photographs are included
