Acropyga is a genus of small formicine ants. Some species can be indirect pests. A. acutiventris, which is found from India to Australia, tends subterranean, root-feeding mealybugs of the species Xenococcus annandalei. Living, gravid females are carried in the jaws of A. acutiventris queens during their nuptial flight, to establish the symbiotic association in founding colonies. Other Acropyga species have relationships with different species of mealybugs, and it could be a trait common to the whole genus.[3]
Description
Acropyga are smaller than 3.5 millimetres (0.14 in), with a compact, stocky body. They have antennae with 10 or 11 segments (including the scape), short palps and reduced eyes with four to 30 individual ommatidia. In some species, the eyes are completely absent.[4]
Distribution
Acropyga is found in the Americas, southern Africa, India to Southeast Asia and Australia . A. paleartica is known only from Greece. Fossil specimens of Acropyga have been recovered from the Burdigalian stage. Dominican amber deposits and several individuals are preserved carrying Electromyrmococcus mealybugs.[5] These fossils represent the oldest recorded record of the symbiosis between mealybugs and Acropyga species ants.[5] They are found in leaf litter and forage on low vegetation, and will nest in various sites, including soil, bark and rotten logs.[4]
