AI Article Synopsis
- Pheidole is a highly diverse group of ants, with over 630 species in the Neotropical Region, and this study focuses on the ant fauna of Colombia.
- The study provides a detailed re-description of the worker subcastes of Pheidole praeusta and identifies it as a trimorphic species, introduces Pheidole amata as a junior synonym, and recognizes Pheidole rogeripolita as the first New World species with a 5-segmented antennal club.
- Additionally, the research includes revised descriptions for historically documented species, new species records for Colombia and South America, and features multifocus photographs of the highlighted ant species.
Article Abstract
Pheidole is one of the most diverse groups of ants in the World, with more than 630 species known from the Neotropical Region. As part of studies on the ant fauna of Colombia, a contribution to the taxonomy of these ants is presented here. The worker subcastes of Pheidole praeusta Roger are redescribed, this being the first record of a trimorphic species outside the Nearctic region. Pheidole amata Forel is proposed as a junior synonym of Pheidole praeusta. Pheidole rogeripolita Longino is identified as the first species in the New World with a 5-segmented antennal club, and the third species with such antennal club in the world. Pheidole distorta Forel, a species described 120 years ago, is redescribed, and notes on its reproductive caste are offered. The description and diagnosis of the Pheidole iceni Fernndez soldier is amended. New species records for the country and South America are listed. Multifocus photographs of P. praeusta, and P. rogeripolita are offered.

Over five hundred non-native ant species have spread worldwide, including many that have severe effects on biodiversity, are serious economic pests, or threaten human health and agriculture. The number of species in the Mediterranean is steadily increasing, with Italy being a prominent example. We provide risk screenings for non-native ant species in Italy using a Terrestrial Species Invasiveness Screening Kit using current climate conditions and future predictions.

Invasive red imported fire ants () create a serious threat to public safety, agriculture, biodiversity, and the local economy, necessitating early detection and surveillance, which are currently time-consuming and dependent on the inspector's expertise. This study marks an initial investigation into the potential of honeybees () to detect and discriminate the odor of through the olfactory conditioning of proboscis extension responses. Deceased were used as conditioned stimuli to ensure relevance to non-infested areas.

Background: This study focused on evaluating the diversity and richness of the edaphic macrofauna in eight banana farms in the western zone of Nicaragua.
Methods: The sampling design was random and descriptive, it was divided into two phases, the first was the collection of the sample, and the second was the classification, coding, and storage of the extracted macrofauna populations. The sampling method employed included the extraction of soil and litter samples.
