Linguamyrmex

Linguamyrmex is an extinct genus of ant in the formicid subfamily Haidomyrmecinae, and is one of only nine genera placed in the subfamily Haidomyrmecinae. The genus contains three described species, Linguamyrmex brevicornis, Linguamyrmex rhinocerus, and the type species Linguamyrmex vladi all known from Late Cretaceous fossils found in Asia.

==History and classification== Linguamyrmex is known from a total of four adult fossils. The holotype is specimen number "AMNH BuPH-01" from the American Museum of Natural History; the other three specimens described are also in the same collection, but were not placed as members of L. vladi. The described specimens are of worker caste adults which have been preserved as inclusions in transparent chunks of Burmese amber. The amber specimens were recovered from deposits in Kachin State, in Myanmar. Burmese amber has been radiometrically dated using U-Pb isotopes, yielding an age of approximately 98.79 ± 0.62  million years old, close to the Albian – Cenomanian boundary, in the earliest Cenomanian.
