This species can be separated from others in this genus by the presence of numerous erect hairs on the gaster. It shares the shape of the outer margins of the postpetiole with M. spinosiorHNS, but differs from this species in the shape of the petiolar node and in having more than four erect hairs on the postpetiole.
Sculpturing in posterior section of antennal scrobe well developed and distinct; sculpturing on dorsal surface of mesosoma consisting of large, closely spaced pits; propodeal spines relatively long and thin; dorsal surface of petiole in lateral profile uniformly convex, without distinct dorsal and posterior faces and forming an obtuse angle with the anterior face; in dorsal view, anterior region of postpetiole expanded relative to posterior region; dorsum of postpetiole with more than four erect hairs; dorsum of gaster with numerous erect hairs.
Measurements. Worker (n = 10) - CI 0.90 - 0.98; HL 0.47 - 0.58; HTL 0.26 - 0.34; HW 0.43 - 0.54; ML 0.49 - 0.64; PW 0.30 - 0.40; SI 0.62 - 0.66; SL 0.27 - 0.35.
This is the southernmost species of MayriellaHNS and occurs in generally drier sites compared to other species. Although widely distributed it shows minimal geographic variation in the characters examined during this study. Biologically, this species is found primarily in drier habitats such as sclerophyll woodlands, low scrub, ti-tree scrub and coastal heath and less commonly in wet sclerophyll and rainforests. Nests occur in soil in the open or under stones or other objects on the ground, and in rotten wood.
Found most commonly in these habitats: 2 times found in wet sclerophyll, 4 times found in eucalypt woodland, 2 times found in Coastal Heath, 1 times found in dry sclerophyll, 1 times found in wet sclerophyl forest, 2 times found in closed forest, 0 times found in Eucalyptus forest, 2 times found in Radiata pine plantation, 0 times found in sandstone gully, 0 times found in ti-tree on sandstone ridge, ...
Found most commonly in these microhabitats: 2 times under stone, 0 times in soil, 0 times in sand, 1 times in rotten log, 0 times under orck, 0 times traps, 1 times sifted leaf litter, 0 times pocket between granite rocks, 0 times pit fall trap, 0 times nest under stone, 0 times nest in soil, ...
Collected most commonly using these methods: 2 times pitfall, 1 times Litter sample.
Elevations: collected from 15 - 1500 meters, 679 meters average
