Etymology. From the Tupi work “ atyra ”, stiff hair, referring to the hairs on the protibia of workers.

Imago. Unknown.

Worker ( Figs. 5 View FIGURE 5 , 22 View FIGURE 22 C, 24E–F). Head capsule large and rounded, light brown, paler anteriorly, with sparse bristles and without short hairs. Postclypeus large and inflated, pale colored, with 1–2 bristles on each lobe. Fontanelle large and distinct, located in a depression near the center of head capsule. Mandibles similar to those of R. xanthochiton . Thoracic nota light brown, paler than head capsule; without bristles or hairs in the middle; pronotum with bristles along all margins; meso- and metanotum with a row of bristles on posterior margin. Procoxa with 5–6 long spine-like bristles on anterior surface, usually 4 along a straight line ( Fig. 5 View FIGURE 5 C). Meso- and metacoxa with a distinct longitudinal row of 3–4 thick, long bristles on outer surface (almost as thick as the ones on the anterior surface of the procoxa). Protibia thin and elongate, with an irregular row of spine-like bristles along inner margin ( Fig. 5 View FIGURE 5 B). Tergites light brown, about the same color of thoracic nota, with two rows of long, straight bristles, one along posterior margin and another near middle, and many hairs of variable size on entire surface. Dehiscent glands small, located mostly inside the thorax and barely extending into the abdomen. Enteric valve unsclerotized; ridges roughly rectangular (when fully distended, like in Fig. 24 View FIGURE 24 F), reticulated with well-defined pentagonal or hexagonal cells; cells are larger near margins and become smaller toward a raised point located anteriorly ( Fig. 24 View FIGURE 24 F). Measurements in Table 2 View TABLE 2 .

Comparisons. The workers of R. atyra are larger than most other species of Ruptitermes except R. cangua and R. xanthochiton . They can be recognized by the presence of 5–6 long spine-like bristles on procoxa, a row of 3–4 long and straight bristles on meso- and metacoxa, the relatively small dehiscent glands, and the small number of hairs on head capsule.

Distribution. From Panama to western Amazonia, in forest habitats ( Fig. 26 View FIGURE 26 ).
