This species inhabits sites at elevations between 120 and 590 m in tropical rainforest, semideciduous forest, bamboo forests, crops, and pastures. There is no further information available regarding the H. marielleae biology, besides nesting in the leaf-litter or inside natural cavities of the superficial soil layers, given that specimens were collected with winkler extractors. (Ulyssea & Brandao, 2021)
Identification
Regular and longitudinal striae on head dorsum, parallel towards posterior margin; long scape; vermicular striae on mesosoma; dorsal margin of petiole discontinuous; ventral surface entirely striate; transverse striae; postpetiole covered with thick, regular and longitudinal striae, slightly anastomosed; subpostpetiolar process sculptured on laterobasal region, midbasal region smooth; long striae on tergum of first gastral segment; body with many thick and unbranched setae.
Hylomyrma marielleae is similar to Hylomyrma longiscapa regarding the body size and the sculpture pattern. However, H. marielleae can be easily distinguished from H. longiscapa (characteristic in parentheses) in the thick and dark setae (vs. thin and light), and the transverse striae on the ventral surface of petiole weakly marked (vs. well-marked). Both species have broad distribution in the center-north of South America, however H. longiscapa occurs in many localities in eastern portions of Brazil (from northeast to southeast regions) (Fig. 83) where H. marielleae does not occur (Fig. 85). One queen collected in French Guiana [USNMENT00536047] has lighter setae when compared to the other specimens evaluated here.
