Ants (family Formicidae in the order Hymenoptera) are the most species-rich of all social insects, with more than 12,000 described species and many others awaiting description. [1] Formicidae is divided into 21 subfamilies , of which 17 contain extant taxa , while four are exclusively fossil . [ 2 ]
Formicium is an extinct collective genus of giant ants in the Formicidae subfamily Formiciinae. The genus currently contains three species, Formicium berryi, Formicium brodiei, and Formicium mirabile. All three species were described from Eocene aged sediments. [1]
The antennae of the worker ants contain nine segments which is common among all species of Brachymyrmex. [13] [12] B. patagonicus have long hairs along the mesosoma and relatively large eyes compared to the other species in the Brachymyrmex genus. [13] On the dorsal surface of the gaster, the distribution of appressed hairs is sparse. [13]
Carpenter ant (Camponotus sp.)The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development.. Formicines retain some primitive features, such as the presence of cocoons around pupae, the presence of ocelli in workers, and little tendency toward reduction of palp or antennal segmentation in most species, except subterranean groups.

Lasius americanus workers are often a shade of dusty brown that have lighter semi-translucent legs. Antennae do not have any erect setae (stiff hair like structures), and propodeum and back legs typically have very few near their base.
Brownimecia is an extinct genus of ants, the only genus in the tribe Brownimeciini and subfamily Brownimeciinae of the Formicidae. Fossils of the identified species, Brownimecia clavata and Brownimecia inconspicua, are known from the Late Cretaceous of North America. The genus is one of several ants described from Late Cretaceous ambers of New ...
