Kugler (1994) - Most similar to but not quite like other species in the germaini species group. WL 0.75mm. Eye very small. Clypeal apron convex. Metanotal groove strong. Propodeal spines very long, strongly inclined dorsad and divergent. Petiole long (PetL/PW 0.95), with prominent keel. Sting apex strong, with dorsal flange. Sides of head below eye, mesosoma, and petiolar node areolate; coarsely so on mesosoma. No erect hair on scapes. Head, mesosoma dorsum, nodes, and gaster T1 with stiff, erect-suberect hairs and shorter, more abundant, appressed-decumbent hair.

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.

Kugler (1994) - Holotype. TL 2.8, HL 0.67, HW 0.56, SL 0.48, EL 0.03 (8 facets), PW 0.37, WL 0.75, SpL 0.22, PetL 0.35, PpetL 0.17mm, CI 0.83, OI 0.05, SI 0.86, PSI 0.29.
The following supplements Kempf (1962b). Mandible triangular, with 5 teeth decreasing in size to base. Clypeal apron evenly convex; body of clypeus projecting over mandibles. Frontal lobes narrow (FL W /HW 0.29). Eyes small, circular, somewhat sunken in head. Petiolar peduncle long (PetL /PW 0.95), with strong keel and dentate inferior process. Postpetiole highest in caudal half; dorsal view subtrapezoidal as in Fig. 49.
Posterior head areolate and more coarse than elsewhere on head. Intervals shiny, but dulled somewhat by vestigial microsculpture. Areolate sculpture on petiolar node not as well defined as on head and mesosoma and even more effaced on postpetiolar node. Nodes roughened by vague microsculpture.
Color uniformly golden-brown.
