Worker ( Figs. 13 View FIGURE 13 , 22 View FIGURE 22 I, 25B–C). Head capsule rounded, yellow, paler anteriorly, with a few bristles and no short hairs. Postclypeus large and inflated, paler than head capsule, with one long bristle near the center of each lobe. Fontanelle small and inconspicuous, a little paler than head capsule. Frontal marks rounded, paler than head capsule. Mandibles similar to those of R. xanthochiton ; notch on left mandible forming an angle of about 45°. Thoracic nota yellow, paler than head capsule, with bristles along margins only, and no short hairs. Procoxa with 4 spine-like bristles on anterior surface, arranged along a curved line ( Fig. 13 View FIGURE 13 C). Meso- and metacoxa without spinelike bristles. Profemur without thick bristles on inner margin, with many thin bristles of variable size arranged irregularly. Protibia slender, not inflated, with two irregular rows of spine-like bristles along inner margin ( Fig. 13 View FIGURE 13 B). Tergites yellowish, hyaline, paler than thoracic nota, with two rows of bristles and many short hairs on surface. Dehiscent glands small, usually reaching only the first abdominal segment, sometimes the second one. Enteric valve unsclerotized; ridges moderately elongate, reticulated with large and faint pentagonal or hexagonal cells; cells become somewhat smaller near a raised region located on the anterior part of the ridge, which has a distinct, nipple-like process in the middle ( Fig. 25 View FIGURE 25 B–C). Measurements in Table 2 View TABLE 2 .

Comparisons. The workers of R. maraca can be recognized by their small size, yellow head, inflated postclypeus and inconspicuous fontanelle.

Distribution. Known only from the grasslands of Roraima, Brazil ( Fig. 28 View FIGURE 28 ).
