HISTORY AND CLASSIFICATION
The single Haidomyrmodes species, Haidomyrmodes mammathus, is known from fossil insects that are inclusions in transparent chunks of French amber . The genus was first described by paleoentomologists Vincent Perrichot and André Nel in 2008. The sister genus, Haidomyrmex, is more diverse with three described species, Haidomyrmex cerberus, Haidomyrmex scimitarus and Haidomyrmex zigrasi, all described from fossils in Burmese amber . While the type specimen of Haidomyrmex cerberus was collected in the early 1900s and deposited in the Natural History Museum in London, a description of the specimen did not occur until 1996 with a paper by the Russian paleoentomologist Gennady M. Dlussky. Both H. scimitarus and H. zigrasi were described in the same 2012 paper by Phillip Barden and David Grimaldi . The third genus, Haidoterminus, and its single species, Haidoterminus cippus, were described in 2013 from Canadian amber. This extended the age range for the tribe by an additional 20 million years into the Late Cretaceous and expanded the geographic range into North America.
In the sphecomyrmins,
Baikuris is known from four species. Both B.
mandibularis, and B. miriabilis were described in 1987 by Dlussky from
a group of fossil males found in Taymyr amber while the third species,
B. casei, was described in 1997 from New Jersey amber. A fourth
species was described from Charentes amber as B. maximus. Both
Cretomyrma species, C. arnoldii and C. unicornis are also described
from Taymyr amber specimens, with their descriptions being published
by Dlussky in 1975. In the same descriptive paper as Cretomyrma was
another new monotypic genus, which Dlussky named "Palaeomyrmex";
however, this name was already preoccupied by Palaeomyrmex , which
Oswald Heer described in 1865, and the Taymyr amber genus was given a
new name, Dlusskyidris, in 1994 by B. Bolton. Fossils belonging to
the subfamily were first discovered in exposures of the
Magothy Formation at
Cliffwood Beach, New Jersey
The eighth genus of the subfamily, Zigrasimecia, was studied by
Barden and Grimaldi with its description being published in 2013. The
genus contains the type species
Zigrasimecia tonsora, which is known
from a solitary dealate female preserved in Burmese amber. While
noting the close relationship between
Zigrasimecia and Sphecomyrmodes,
Barden and Grimaldi did not specifically place
Zigrasimecia into any
