Kugler (1994) - germaini species group. As in Rogeria germaini but: 1) metapleural lobes larger, triangular, and 2) rugae on promesonotum more rounded and thicker than on head; one ruga begins near anteroventral corner of pronotum and continues unbroken to the metanotum.
Similar to Rogeria tonduzi.

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 have not been collected.

Holotype and Paratype. TL 2.6-3.4 (3.3), HL 0.63-0.80 (0.78), HW 0.53-0.70 (0.67), SL 0.45-0.56 (0.55), EL 0.05-0.08 (0.08) (6-12 facets), 43 PW 0.39-0.51 (0.51), WL 0.65-0.87 (0.86), SpL 0.12-0.20 (0.175), PetL 0.31-0.47 (0.44), PpetL 0.17-0.23 (0.21)mm, CI 0.83-0.88 (0.86), OI 0.09-0.12 (0.12), SI 0.79-0.85 (0.82), PSI 0.19-0.23 (0.20). N=10
Dentition as in Rogeria germaini. Nuchal groove forms a weak notch in lateral view. No clear angle between anterior and dorsal faces of pronotum. Spiracle faces slightly caudad, posterior edge within one diameter of nearest edge of propodeum. Petiolar peduncle with a sharp, but not lamellate keel. Petiolar node profile angular. Postpetiolar node in dorsal view shaped as in Figs. 24 or 49; sternum flat. Sting apparatus as described for germaini.
Divergent longitudinal rugae on frontal lobes grade into areolate sculpture at level of eyes. Sculpture of posterior head transversely arching rugose to rugose-areolate. Laterodorsa and sides of head longitudinally rugose-areolate; sides may be effaced to nearly smooth. Head microsculpture vestigial; intervals nearly smooth, quite shiny. Anterior face of pronotum areolate, becoming vermiculate-rugose on disc. Thick, rounded rugae of pro meso no tum may merge, but are rarely joined by cross-ridges. Rugae on meso- and metapleura sharper and more separated. Anterior and dorsal faces of petiolar node smooth. Sides and posterior faces of node in holotype longitudinally rugose-areolate, but weaker and more rugose in Trinidad specimen and nearly smooth in specimens from Peru. Microsculpture weak or absent; integument shiny.
Scapes with decumbent to suberect hair (holotype) or with short, uniformly subdecumbenthair. Head dorsum with subdecumbent to erect hair. In most, mandibles, frontoclypeal region, antennae and legs brownish-yellow; other parts rusty brown, becoming darker, almost black, on dorsa of mesosoma and petiole. Trinidad and Guyana specimens lighter on all parts.
TL 3.6-3.7, HL 0.76-0.80, HW 0.69-0.70, SL 0.52-0.57, EL 0.14-0.15, PW 0.58-0.60, WL 0.95-1.00, SpL 0.18-0.20, PetL 0.46-0.52, PpetL 0.23-0.24mm, CI 0.88-0.90, SI 0.76-0.81, PSI 0.18-0.21. N=4.
Besides the usual features of an alate female, differing from the worker in the following ways. Mandible with 7 teeth or 3 teeth and 5 denticles. Parapsidal furrows not distinct from furrows in sculpture. Propodeal spines project caudad or posteroventrad. Rugae on sides of pronotum almost vertical to shoulder, then bend across the anterior face of the pronotum. Mesonotal rugae longitudinal with occasional fusions and cross-ridges. Wing venation most similar to that of Rogeria stigmatica. Radial sector and median veins long, nearly reaching wing margin; r-m vein present.
The name lirata refers to the characteristic rugae of the mesosoma, which resemble the ridges thrown up by a plow.
