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.

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.
