| Rogeria bruchi|
Only known from a few specimens.
Kugler (1994) - foreli species group. The five known specimens of bruchi are just like Rogeria foreli with nonprojecting clypeus, weak or absent metanotal groove, and non projecting postpetiolar sternum, but differ in the following ways: 1) Mandible with five large teeth, second to fifth subequal, 2) clypeus with a median notch, 3) eyes smaller than in most foreli.

The following is modified from Kugler (1994): Little is known about these cryptic ants. Collection records typically range from sea level to 1000m, but five species extend higher and two (Rogeria unguispina and Rogeria merenbergiana) can be found at 2000m. Rogeria are generally collected in moist forests (primary or secondary forests, coffee or cacao plantations), but at higher elevations can be found in pastures (Rogeria leptonana, Rogeria merenbergiana). Several species (Rogeria creightoni, Rogeria cuneola, Rogeria foreli) have been found in moist and dry climates. Rogeria foreli is the most unusual, with some members dwelling at over 1800m in the temperate mountains of southern Arizona.
Most species have only been collected as strays or by Berlese or Winkler sampling, from leaf litter and rotten wood, but occasionally among epiphytes and moss (Rogeria belti, creightoni, Rogeria exsulans). Nests of several species (belti, Rogeria blanda, merenbergiana) have been found under the loose bark of rotten logs. Nests of blanda and Rogeria tonduzi have been taken from the trunks of cacao trees. A nest of Rogeria leptonana was found at 1750m under a rock in a pasture.
Nests are rarely found. Males are known for only four species (belti, blanda, leptonana and Rogeria stigmatica) and queens associated through nest series for only nine species.
Only known from workers.
