Head dorsum with thin striae (microsculpture) superimposed on vermicular and longitudinal striae (macrosculpture), interspaces between thin striae indistinguishable. Head lateral and laterodorsal regions with same striation of head dorsum, striae converging to eye margin; gena striate, irregular and semicircular striae circumscribe the torulus, not reaching eye margin. Interspaces between striae on head ventral surface distinguishable.
Mesosoma sculpture similar to head dorsum. Promesonotal junction indistinct. Transverse carina inconspicuous (LV). Metanotal groove discernible by a slight depression (LV). Dorsal margin of mesosoma slightly discontinuous, convex. Propodeal lobe bidentate, dorsal tooth slightly longer and acute than the shorter and blunt ventral tooth; dorsal tooth length 1 / 2 shorter than propodeal spine length. Propodeal spine long, straight (LV), divergent (DV), sculptured. Procoxa striae of uniform thickness; irregular and transverse striae on C2 and C3. Profemur covered with irregular to regular striae, mostly transverse on anterior and dorsal surfaces, longitudinal on apical region. Protibia entirely covered with regular and longitudinal striae.
Dorsal margin of petiole continuous, convex; sculpture similar to mesosoma; ventral surface regular and smooth. Longitudinal and adjacent striae on postpetiole and subpostpetiolar process; dorsal margin of postpetiole subtriangular; subpostpetiolar process prominent, subtriangular.
First gastral segment striation similar to postpetiole striae; long striae on tergum, 11 / 2 × longer than postpetiole length; sternite striation covering entirely the basal region.

Propodeum with irregular striae assuming multiple directions, interspaces distinguishable. Propodeal lobe subquadrate. Petiole mostly covered with longitudinal and irregular striae, interspaces indistinguishable. Postpetiole with longitudinal and anastomosed striae. First gastral tergum striate on basal region. Interspaces between striae smooth. Wings as in Fig. 82E.
Etymology. The name refers to the species size (Latin, immanis = large, huge). Hylomyrma immanis is the largest species of the genus.
Comments. Hylomyrma immanis and H. praepotens are the largest species in the genus (TL 5.67–6.47 mm, WL 1.51–1.58 mm). Both have a long propodeal spine, and an elongated and continuous dorsal margin of the petiole, but H. immanis is easily distinguished by the subopaque integument (shiny in H. praepotens), and the body covered by thin striae with interspaces indistinguishable (thick striae with interspaces distinguishable in H. praepotens). Hylomyrma immanis is more easily sampled than H. praepotens, the former has a broad distribution in the center-north of South America (Fig. 88), whereas the latter is only known from two localities in Colombia, two in Ecuador, and one in Brazil (Fig. 90). Both species co-occur in a locality 7 km NW of Letícia, Amazonas, Colombia.
Distribution. This species is widely distributed in northwest South America (Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, and Venezuela), Trinidad (Trinidad and Tobago), and in eastern portions of Brazil (Fig. 88).
Natural history. This species inhabits forested areas in Atlantic and other tropical rainforests of South America. Most specimens were sampled in leaf-litter with winkler extractors, which suggests that H. immanis nests between leaves, in fallen logs, rotten wood, or inside natural cavities of the superficial soil layers.
