This species is only known from its type locality, and inhabits areas at elevations between 1340 and 2200 m. Most specimens were collected from rotten wood, humus, and leaf-litter submitted to Berlese-Tüllgren funnels. (Ulyssea & Brandao, 2021)
Identification
Irregular and longitudinal striae on head dorsum diverge towards posterior margin; rugose striae on mesosoma and petiole; promesonotal junction and metanotal groove distinguishable by a slight depression (LV) and altered sculpture (DV); dorsal margin of petiole discontinuous; subtriangular projection on mesoventral surface of petiole; node ventral surface striate transversely; profemur posterior surface entirely striate; striae transverse and well-marked; protibia extensor surface entirely striate, striae weakly marked; long striae on first gastral tergite.
Hylomyrma mariae is similar to Hylomyrma adelae and Hylomyrma dandarae. Hylomyrma mariae differs from H. adelae (characteristics in parentheses) in the irregular divergent-longitudinal striae on the head dorsum (vs. rugose striae), the distinct metanotal groove (vs. indistinct), the longer propodeal spine (vs. shorter), the profemur posterior surface with striae weakly marked (vs. well-marked), and the dorsum of petiole with rugose striae (vs. irregular and transverse striae). The two species are allopatric; Hylomyrma mariae occurs in northern Colombia (Fig. 88), and H. adelae in Bolivia (Fig. 83). Hylomyrma mariae differs from H. dandarae in the drop-shaped eye (vs. oval), the shorter petiolar node (vs. longer), and the long striae on tergum of the first gastral segment that extends up to its first third (vs. short striae). The two species occur in Colombia (Figs. 83, 88).
