Kugler, C., 1994
These tiny ants are most often taken in berlesate of leaf litter and rotten wood. Some come from siftings under termite mounds and one was collected in a Cattelya orchid. Habitat of most specimens is rain forest or mesic forest, either primary or secondary growth, but one specimen was found in Yucatán thorn forest.

Kugler (1994) - curvipubens species group. Postpetiolar node weakly vaulted and with no posterior peduncle. Anterior edge of sternum strongly produced; posterior and ventral edges merge insensibly. Sting shaft and lancets strong, acute; sting shaft with dorsal flange; lancet with barbule. Sides of head and mesosoma with strong microareolate sculpture that obscures weak macrosculpture and makes intervals opaque. Dorsal face of propodeum without transverse rugulae.

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.
Males and intercastes have been collected in Honduras but have not been described.

Like Rogeria curvipubens, but differing in the following ways in addition to diagnosis. Relative widths of nodes with slightly different ranges (PetW/PetL 0.56-0.70); PpetW/PpetL 1.38-1.52). Sting apparatus of specimens from Oaxaca (paratypes) and Vera Cruz, Mexico with strong, acute sting shaft and lancets as in inermis.
Posterior head with transversely arching rugose-areolate macrosculpture. Compared to curvipubens, rugae on mesosoma dorsum with more lateral spurs that may connect rugae and create areolae on anterior pronotum and on metanotum. Macrosculpture on mesosoma sides absent or weakly rugose-areolate. Dorsal face of propodeum lacks macrosculpture.
Head dorsum with 0-16 hairs suberect hairs; mesosoma dorsum with 1-8 pairs (usually 2-7). Erect hair on gaster T1 usually limited to posterior margin, but entirely absent from Jalisco specimen and entirely covering the tergum of the Yucatán specimen. The Yucatán specimen is also unique in having some stiff, spatulate hairs on head, mesosoma and gaster.
Paratype and Nontype. TL 2.3-2.5, EL 0.53-0.56, HW 0.45-0.50, SL 0.35-0.38, EL 0.10-0.11, PW 0.39-0.45, WL 0.65-0.72, SpL 0.11-0.14, PetL 0.22-0.25, PpetL 0.13-0.15mm, CI 0.85-0.89, SI 0.76-0.78, PSI 0.16-0.19. N=2
Queen as in Rogeria curvipubens, except for shape of postpetiole, sting, and sculpture as in workers of cuneola. Mandibles with 6 or 7 teeth. Sides of head and mesokatepisterna strongly microareolate and opaque. Paratype queen with erect-suberect hair over whole gaster T1.
Holotype locality. MEXICO: Oaxaca State, 1 mi. E Reforma, 15-VIII-1973, litter, tropical evergreen forest (A. Newton) Museum of Comparative Zoology.
Paratype localities. MEXICO: 14 workers, holotype locality The Natural History Museum, Charles Kugler Collection, Los Angeles County Museum of Natural History, MCZ, Museu de Zoologia da Universidade de Sao Paulo, National Museum of Natural History; 1 worker, 1 queen, Oaxaca State, 1 mi. E Reforma, near Tuxtepec, 12-15-VIII-1973, litter forest floor (A. Newton) [3 stings, 1 worker coated for SEM] MCZ.
The name cuneola (L., small wedge) refers to the shape of the postpetiolar sternum in lateral view.
