Acropyga Arnoldi
''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. Description ''Acropyga'' are smaller than , 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. Distribution ''Acropyga'' is found in the Americas, southern Africa, India to Southeast Asia and Australia. ''A. paleartica'' is known only from Greece.

Burdigalian
The Burdigalian is, in the geologic timescale, an age (geology), age or stage (stratigraphy), stage in the early Miocene. It spans the time between 20.43 ± 0.05 annum, Ma and 15.97 ± 0.05 Ma (million years ago). Preceded by the Aquitanian (stage), Aquitanian, the Burdigalian was the first and longest warming period of the MioceneEdward Petuch, Ph.D. Florida Atlantic University, Department of Geosciences. and is succeeded by the Langhian. Stratigraphic definition The name Burdigalian comes from ''Burdigala'', the Latin name for the city of Bordeaux, France. The Burdigalian Stage was introduced in scientific literature by Charles Depéret in 1892. The base of the Burdigalian is at the first appearance of foram species ''Globigerinoides altiaperturus'' and the top of magnetic chronozone C6An. , an official GSSP for the Burdigalian had not yet been assigned. The top of the Burdigalian (the base of the Langhian) is defined by the first appearance of foram species ''Praeorbulina gl ...

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...

Acropyga Epedana
''Acropyga epedana'' is an ant in the subfamily Formicinae. It lives permanently underground in the Chiricahua Mountains in Arizona and forms a mutualistic association with the mealybug '' Rhizoecus colombiensis''. Description ''Acropyga epedana'' is a tiny pale golden-brown ant with a few erect hairs but many dense appressed hairs. The reproductives have normal compound eyes but the workers have tiny eyes and avoid exposure to light. These ants are very similar in appearance to '' Acropyga goeldii'' and '' Acropyga palaga'' and may be a northern population of ''A. goeldi''. However, there are differences in the extensions to the penis valves that make it likely that the three are in fact separate species. The head of ''Acropyga epedana'' is smaller than that of the other two species. The total length of a worker is . Distribution ''Acropyga epedana'' is found in the Chiricahua Mountains in Arizona at elevations of between and its range probably extends southwards into the S ...
