A new species of (Coleoptera, Scarabaeidae, Melolonthinae) from Alabama, United States of America.

A new species, MacGown & Hill, (Coleoptera: Scarabaeidae: Melolonthinae: Melolonthini), is described from east central Alabama, USA. Three other species of , Skelley, Howden and (Cartwright) are known to occur in the United States. We discuss differences between these species and provide an updated identification key to the genus.

First Report of Imported Fire Ants, and X (Hymenoptera: Formicidae) from Kentucky.

Since their introduction into the United States in the early 1900's, imported fire ants, namely Buren (Red Imported Fire Ant), Forel (Black Imported Fire Ant), and their hybrid form X have spread throughout portions of the USA, especially in the southeastern region. Imported fire ants are a serious invasive and economically significant species in the USA and elsewhere, and their spread into new parts of the country is of great concern. Although early models predicted that the fire ants would not be able to survive very far north into the USA, these ants have nonetheless successfully continued their spread into higher latitudes.

The global distribution of known and undiscovered ant biodiversity.

Invertebrates constitute the majority of animal species and are critical for ecosystem functioning and services. Nonetheless, global invertebrate biodiversity patterns and their congruences with vertebrates remain largely unknown. We resolve the first high-resolution (~20-km) global diversity map for a major invertebrate clade, ants, using biodiversity informatics, range modeling, and machine learning to synthesize existing knowledge and predict the distribution of undiscovered diversity.

First record of the genus Leptanilloides (Hymenoptera: Formicidae: Dorylinae) from the United States.

We describe a new species of the Neotropical genus Leptanilloides, L. chihuahuaensis sp. n.

A review of the Nearctic Odontomachus (Hymenoptera: Formicidae: Ponerinae) with a treatment of the males.

The ant genus Odontomachus Latreille in the United States is reviewed. Six species are treated: O. brunneus (Patton), O.
