Due to the unique sociobiology of ants, their omnipresence in terrestrial ecosystems, and the relatively broad foundation of knowledge on their behavior, ecology, diversity, and systematics, interest in myrmecology is burgeoning and will continue to do so. The Neotropical region harbors one of the highest ant diversities and also densities of ant researchers in the World. It is, therefore, timely to invite myrmecologists to submit original manuscripts and review articles on various aspects of knowledge concerning Neotropical ants, for a special issue of Psyche. Potential topics include, but are not limited to:

• Taxonomy (revisionary work on small groups encouraged)
• Evolution and phylogeny
• Natural history and behavior
• Ant bioinformatics
• Biogeography
• Guilds and functional groups
• Ant diversity
• Ant/plant relationships
• Biological indicators, invasive species, and conservation
• Comparison between the ant fauna of the Neotropics and other biogeographical regions

Before submission authors should carefully read over the journal's Author Guidelines, which are located at http://www.hindawi.com/journals/psyche/guidelines.html. Prospective authors should submit an electronic copy of their complete manuscript through the journal Manuscript Tracking System at http://mts.hindawi.com/ according to the following timetable:
