Little is known about the biology of Monomorium maryannae.
Identification
Sparks et al. (2015) - A member of the M. rothsteini species group.
A large amber orange with a deeply concave clypeal margin and strigate frons (in a majority of specimens). The dorsolateral angles of the propodeum almost form a right angle in most specimens.
This is one of the more variable species with differences in size and sculpture observed across its range. In particular, specimens from the northern part of the Northern Territory and Western Australia are larger and more robust than those from Queenland. (Sparks et al. 2014) also found this species to be one of the most genetically diverse.

Description
Worker
(n=9). HW 0.78–0.98, HL 0.86–1.03, EL 0.16–0.18, PMH 0.29–0.49, PH 0.25–0.37, PNH 0.2–0.25, LHW 0.43–0.6, EW 0.10–0.12, PML 0.51–0.68, ML 0.88–1.17, PL 0.41–0.55, PNWdv 0.21–0.31.
Large species with a medium sized, rectangular head; posterior cephalic margin broadly v shaped. Anterodorsal margin of the clypeus deeply concave with frontolateral carinae produced anteriorly, extending well beyond anteroventral margin, with acute anterolateral angles and with small, rounded, preapical teeth or nodules. Anteroventral margin of the clypeus without a small median projection, margin appears straight. Frons strigate, extending well above antennal lobes or rarely restricted to and between antennal lobes; coarse lateral cephalic strigae reach anterior eye margin. Eyes medium, EW 0.20–0.23 x LHW, 11 ommatidia in longest vertical axis, 10 in longest horizontal axis.
Mesonotum strigulate with shallow alveolae on lateral curvature, in metanotal groove and extending onto the posterior region of the mesonotum, smooth medially; posterior mesonotum appears raised with a faint horseshoe shaped margin in some specimens. Mesopleuron alveolate with a few strigae extending anteriorly from metanotal groove and in anterodorsal corner. Propodeum in lateral view with dorsolateral angles almost forming a right angle in most specimens, tending to a more obtuse angle in a minority of specimens; sculpture alveolate with strigae extending over metapleural gland bulla and between spiracle and posterodorsal corners. Dorsal surface of propodeum with raised transverse anterior carina, transverse strigae present in a majority of specimens, longitudinal carinae weak, forming broken lines or absent. Petiole node width when viewed from above between 2 and 2.5 x eye width; shape in posterior view tapering from broad midline to rounded apex, in lateral view anterior and posterior faces sub parallel, apex broadly rounded from higher anterior face to lower posterior face. Petiole and postpetiole finely reticulate but not extending onto dorsal surface. T1 with fine reticulate sculpture restricted to anterior third or absent.
Head, mesosoma and legs light to dark amber orange, some specimens with mesosoma and legs infuscated, petiole and postpetiole infuscated on dorsal half, metasomal tergites dark brown, sternites amber, hairs dull yellow.
