Formiciinae

Formiciinae is an extinct subfamily of ants known from Eocene deposits in Europe and North America.

Genera

The type genus is Formicium, with the genus Titanomyrma being defined in 2011. Formicium consists of the explained types, which are known from fossil wings. Formicium is understood from three varieties. Formicium mirabile, named by Theodore D. A. Cockerell in 1920, and Formicium brodiei, named by John O. Westwood in 1854, are both recognized from fore wings located between Eocene of Bournemouth, Dorset, England. The third species, Formicium berryi was named by Frank M. Woodworker in 1929 from the center Eocene Claiborne Development in Puryear, Tennessee, United States. He misidentified the development as the Wilcox Development. F. berryi was the first related occurrence of the genus and, up until 2011, the subgenera in N America. With the definition of Titanomyrma, the 2 types already defined from total body specimens, Formicium giganteum and F. simillimum, were transferred to the brand-new genus as Titanomyrma giganteum and also T. simillimum specifically. Titanomyrma likewise contains a 3rd species, T. lubei described in the same paper as the genus, which is the 2nd member of the subfamily recognized from The United States and Canada.

Size

While workers in the subfamily have not been located, queens and males for T. giganteum and also T. simillimum is understood, and T. lubei is known as a solitary queen. The typical dimension for the queens and males in Titanomyrma amounts to that of a few of the largest contemporary ants recognized. The queens of Dorylus wilverthi presently get to similar sizes, as much as 52 millimeters (2.0 in), as the tiniest varieties of Titanomyrma, T. lubei.

Formiciinae members were limited to staying in regions with a mesic damp environment and an ordinary mean annual temperature of 20 ° C (68 ° F) or higher. This is similar to the limited varieties of the largest varieties of modern-day ants. The spread of the subfamily from Europe to North America is proposed to have been across the North Atlantic landbridges present in the Eocene. While the typical temperature levels for this path are believed to have actually been lower than the array required for Formiciinae species, a collection of warmer events throughout the Eocene are recommended as assistants in the crossing.
