All specimens examined by Ulyssea & Brandao (2021) were found in leaf-litter samples of wet forests, which suggests that nests are located in fallen logs, rotten wood, between leaves, or inside natural cavities of the superficial soil layers.
Identification
Rugose and divergent striae on head dorsum; rugose striae on mesosoma; promesonotal junction and metanotal groove indistinct; dorsal margin of petiole discontinuous; subtriangular projection on mesoventral surface of petiole; irregular and transverse striae on node dorsum; ventral surface of node striate; striae on profemur posterior surface and protibia extensor surface weakly marked; long striae on tergum of first gastral segment.
Hylomyrma adelae is similar to Hylomyrma dandarae and Hylomyrma mariae. Hylomyrma adelae can be distinguished from H. dandarae (characteristics in parentheses) based on the following characters:
- drop-shaped eye (vs. oval)
- rugose striae on the head dorsum (vs. irregular divergent-longitudinal)
- indistinct promesonotal junction and metanotal groove (vs. distinct)
- tergum of the first gastral segment with long striae (vs. short striae).
Both species occur in nearby geographic areas of Bolivia (Fig. 83), H. adelae in Cochabamba and H. dandarae in La Paz.
Hylomyrma adelae differs from H. mariae in:
- the rugose striae on the head dorsum (vs. irregular divergent-longitudinal)
- the indistinct metanotal groove (vs. distinct)
- the shorter propodeal spine (vs. longer)
- the profemur posterior surface with well-marked striae (vs. weakly marked)
- the dorsum of petiole with irregular and transverse striae (vs. rugose striae).
Also, the two species are allopatric; H. adelae in Bolivia (Fig. 83), and H. mariae in Colombia (Fig. 88).
