Rogeria micromma

Identification
Kugler (1994) - WL 0.45-0.52mm. Clypeal apron medially flattened. Eye tiny. Postpetiolar node subrectangular in dorsal view and not strongly vaulted in side view; anterior lip of sternum not prominent, posterior edge angular in side view. Sides of head and mesosoma and dorsal face of propodeum opaque with dense microareolate sculpture. Laterodorsa and sides of head also finely macroareolate. Propodeum free of macro sculpture. No erect hair on scapes or extensor surfaces of legs. Dorsa of head, mesosoma, nodes and gaster T1 with short, appressed hairs and longer, erect to suberect hairs. Mesosoma dorsum with 8-10 pairs of erect hair; each node with 2 pairs of posterodorsally projecting hairs.

Distribution
This taxon was described from Suriname.

Worker
Kugler (1994) - TL 1.7-1.8, HL 0.44-0.51, HW 0.37-0.45, SL 0.28-0.35, EL 0.02-0.04 (2-5 facets), PW 0.28-0.30, WL 0.45-0.52, SpL 0.07-0.08, PetL 0.17-0.18, PetW 0.10-0.13, PpetL 0.10-0.11, PpetW 0.13-0.15mm, CI 0.84-0.88, OI 0.05-0.08, SI 0.76-0.79, PSI 0.15-0.16, MHI 0.92-0.96. N=3

The following supplements diagnosis and Kempf (1961). Mandibles 5-toothed to 6-toothed; basal tooth not larger than penultimate basal. Mesosoma profile of holotype interrupted by a weak metanotal groove followed by two transverse carinulae, but profiles of La Poulle and Brazil specimens uninterrupted. Brazil specimen with narrower propodeal spines than in types, and propodeal spiracle closer to posterior edge of propodeum. Petiole short (PetL/WL 0.35-0.38), with ventral keel and tooth.

In Surinam specimens, vague microareolate microsculpture densely covers head, dorsum of mesosoma, dorsal face of propodeum, petiole and postpetiole of types, producing a weakly shining, granular appearance. Brazil specimen similar, except for smoother ventral petiolar peduncle and postpetiolar dorsum. Sides of mesosoma and posterior surface of head more distinctly microareolate. Anterior of pronotal disc with 1 to 2 transverse rugae followed by longitudinally rugose to areolate-rugose macrosculpture that disappears into microsculpture on meso- and metanota. Sides of mesosoma with sparse, faint longitudinal rugulae on meso- and metapleura. Nodes microareolate; more effaced on postpetiole.

Erect hairs of Dirkshoop specimen all trichoid; but thicker and stiff on the La Poulle specimen, at least some cuneate; erect hairs on the Belem specimen seem intermediate.

Color brownish-yellow; legs, mandibles and antennae sometimes slightly lighter. Frontoclypeal region not lighter than rest of head.
