| Rogeria terescandens|
Kugler, C., 1994
Specimens of Rogeria terescandens have been taken from trees in lowland forest on the Pacific side of Costa Rica. The holotype was collected in a two week old treefall by general collecting on trunks. The paratype was on or beneath a thick epiphyte mat on the base of a fallen branch (J. Longino unpublished field notes). Longino also reports (Ants of Costa Rica 1998) "The ALAS project at La Selva Biological Station produced two more workers, from a canopy fogging sample. The species is apparently a rare canopy dweller."
Kugler (1994) - scandens species group. Like that of Rogeria scandens, except: 1) Propodeal spines shorter, 2) petiolar node lower, more slender (PetW/PetL0.40-0.41), 3) postpetiole narrower (PpetW/PpetL 1.08-1.16), and 4) macrosculp ture very weak, especially on mesosoma and waist, and 5) eye slightly smaller.

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.

Also differing from Rogeria scandens in the following ways. Mandible with 6 teeth. Profile of mesosoma dorsum almost evenly convex; no metanotal groove or ridge at front of propodeum. Median carinulae on clypeus weak; no lateral carinulae. Head dorsum densely microareolate; overlain on mid dorsum by wisps of of longitudinal rugulae, on laterodorsa by faint reticulations, and on posterior of head by fragmented, transversely arching rugulae. Microsculpture on sides and posterior head effaced. Mesosoma dorsum, including dorsal face of propodeum, densely microareolate, with superimposed patches of fine rugulose-areolate macrosculpture. Pronotal sides shiny and coriarious with some effaced longitudinal rugulae. Mesopleura and metapleura also shiny near coxae, but more opaque dorsad with microareolate and confused rugulose sculpture. Sides of petiolarnode shiny, with effaced microareolate background and vestigial longitudinal rugulae. Postpetiole smooth and shiny.
Holotype locality. COSTA RICA: Osa Peninsula, Sirena, 8.28N 83.3SW, 50m, 3-III-1982, #0950 (J. Longino) Museum of Comparative Zoology. Paratype locality. 1 worker, holotype locality, 28-V-1981, #1 100 (J. Longino) Los Angeles County Museum of Natural History.
The name of this species refers to sculpture like that of Rogeria scandens, but smoother, as if rubbed (teres L., rubbed off).
