The male and female have a deep depression behind the eyes.
The abdomen is nearly spherical and lacks projecting dorsal humps.
Zephyrarchaea marae inhabits elevated accumulations of leaf litter. In Victorian forests, adults and juveniles were found beneath tree ferns, in both Nothofagus rainforest at Tarra-Bulga and tree-fern-rich eucalypt forests. Its documented settings therefore include raised litter within the moist forest, rather than just the ground surface.
The 2012 paper lists specimens collected in late March and early April 2010. At Sherbrooke Forest on 28 March, elevated litter beneath tree ferns yielded a female and two juveniles. At Mount Worth State Park on 31 March, similar litter yielded a juvenile. On 1 April, the name-bearing male and three juveniles were collected at Tarra Valley. Adults and young from separate forests thus preserve a shared microhabitat beneath tree ferns.
An extinction-risk assessment has not been added yet.
The 2018 joint management plan for Tarra-Bulga National Park identifies invasive plants such as blackberry and Myrtle Wilt disease affecting Nothofagus rainforest as concerns. It calls for targeted weed control, staff training in disease detection and prevention, minimising disturbance during road and facility works, and monitoring rainforest communities. These are regional management provisions for a forest containing verified marae sites.
