Etymology
From the place name Ereyma; -termes from Latin termes.
The etymologies in this section are analytical breakdowns; the roots follow Brown (1956).
Morphology
The descriptions below are an adaptation of the original genus-level accounts; terms follow the meaning of the source, and the original is not transcribed verbatim.
Diagnostic characters
A nasute genus endemic to the Neotropical region. According to later literature, the genus is fairly clearly delimited, its circumscription recognisable from the three castes together: soldier, worker and alate.
Soldier
Head capsule oval, slightly constricted behind the antennal bases; nasus long cylindrical, not upturned in lateral view; clypeus extremely reduced; antennae 12 segments; tibial spur formula 2:2:2.
Worker
Dimorphic, narrow-gap and broad-gap, the narrow-gap morph much commoner than the broad-gap; molar region ridges reduced, but the marginal teeth not lost.

Definition and distribution of the genus
According to Cancello & Cuezzo (2007), Ereymatermes is a Neotropical endemic genus of Nasutitermitinae. The paper describes the new species Ereymatermes piquira (type locality Ilhéus, Bahia, Brazil) and reviews the previously known Ereymatermes rotundiceps (forest along the lower Japurá River, Amazonas, Brazil) and Ereymatermes panamensis (Panama Canal Zone).
Ereymatermes is defined jointly by the soldier, worker and alate castes; the soldier has an oval head capsule slightly constricted behind the antennal bases, a long cylindrical nasus that is not upturned, a much reduced labrum, 12-segmented antennae and a tibial spur formula of 2:2:2; the workers are dimorphic, the narrow-gap type being the more common.
