Two new species of Tetramorium Mayr, namely Tetramorium shivalikensesp. n. and Tetramorium triangulatumsp. n. are described. Tetramorium triangulatumsp. n. belongs to the inglebyi-species group and is described based on worker, queen and male caste, while Tetramorium shivalikensesp. n. belongs to the ciliatum-species group and is described based on worker caste only. Three species viz., Tetramorium caldarium (Roger), Tetramorium tonganum Mayr and Tetramorium urbanii Bolton represent first records from India. The male caste is described for the first time in the case of Tetramorium tonganum. Among these, Tetramorium caldarium is a tramp species which extends its limit to India as well. A revised key to the Indian ants of this genus is also provided herewith.

Situated in the Eastern Mediterranean, the island of Cyprus is a biodiversity hotspot hosting an important number of endemic species. In recent years, its myrmecofauna has been increasingly enriched with the detection of both new alien and native species as well as the description of new endemic taxa. Nevertheless, earlier reports of dubious taxa remaining in scientific literature constitute an impediment towards the study of the island's biodiversity.

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.

An insect neuroactive helix ring peptide called U-MYRTX-Tb1a (abbreviated as U) from the venom of the ant, . U is a 34-amino-acid peptide that is claimed to be one of the most paralytic peptides ever reported from ant venoms acting against blowflies and honeybees. The peptide features a compact triangular ring helix structure stabilized by a single disulfide bond, which is a unique three-dimensional scaffold among animal venoms.

Ant behavior relies on a collection of natural products, from following trail pheromones during foraging to warding off potential predators. How nervous systems sense these compounds to initiate a behavioral response remains unclear. Here, we used chemotaxis assays to investigate how ant compounds are detected by heterospecific nervous systems.
