A rarely collected species that is only known from the worker caste.
Identification
Kugler (1994) - creightoni species group. Additions to creightoni-group diagnosis. WL 053-0.67mm. Clypeal apron convex. Eye small. Propodeal spines small. Mesosoma low (MHI 0.36-0.96). Postpetiole subrectangular in dorsal view; sternum with distinct, but not projecting anterior lip. Sides of head rugose. Promesonotal dorsum carinate, with broad, shiny intervals. Short erect-suberect hairs on scapes, but not on extensor surfaces of legs.
The carinate macrosculpture of the promesonotum with very shiny intervals serves to differentiate carinata from others of the creightoni group. See also Rogeria nevadensis which has similar sculpture.

Biology
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.

Mandibles with 5 teeth and 0-2 denticles between the two basal teeth; basal tooth larger than penultimate basal. Eyes oval to elliptical. Nuchal groove weak. Posterior outline of head weakly convex to weakly concave. Mesosoma from above broad, angular at shoulders, but strongly constricted behind; metanotum half as wide as shoulders. Propodeal spiracle small, one diameter from posterior edge of propodeum. Metapleural lobes small, rounded. Ventral petiole with weak keel. Postpetiole highest in posterior half. Sting apparatus with slightly lower valve chamber than that of inermis.
Laterodorsa of head rugose-areolate in Puerto Rican specimens. Posterior head transversely arched areolate-rugose. Interrugal spaces on head weakly and irregularly roughened on dorsum; smoother on sides and posterior. Anterior face of pronotum with transverse carinules that continue onto shoulders and curve dorsad. Meso- and metapleura with irregular longitudinal rugae; intervals smooth dorsally, but vestigially microareolate below level of propodeal spiracle. Dorsal face of propodeum mostly smooth with 0-3 transverse rugulae. Petiolar node vaguely microareolate; macrosculpture absent or indistinct on sides. Postpetiole vaguely microareolate on venter; smooth and shiny on dorsum. Gaster smooth and shiny.
Mesosoma dorsum with 10 pairs of erect hairs.
Color brownish-yellow; head and mesosoma slightly darker than rest of body. Some Puerto Rican specimens slightly darker, with reddish hue to head and mesosoma.
