The male has a dark reddish-brown head and thorax.
The legs have darker rings and the abdomen is mottled dark greyish brown and beige.
The male used to describe Austrarchaea tealei measured 2.67 mm long, while the femur of its first leg measured 3.09 mm—longer than the body. Its carapace was 1.08 mm long and 2.35 mm high.
The male has a remarkably large, whip-like component in its sperm-transfer organ. A study published in 2021 used micro-computed tomography on one preserved male from Mossman Gorge. Inside its pedipalp, an appendage near the mouth, the sperm duct branched into two long, slender ducts leading to separate outlet-bearing structures.
In the same study, the secondary outlet-bearing structure was relatively small and partly concealed in Zephyrarchaea mainae and Austrarchaea mascordi. In A. tealei it was exceptionally large, whip-like and exposed. Thus, among the examined relatives sharing a bifurcating internal duct, the size and exposure of the secondary structure differed markedly.
An extinction-risk assessment has not been added yet.
Mossman Gorge, the collecting locality, lies in Daintree National Park. The Queensland government describes joint management by the Jabalbina Yalanji Aboriginal Corporation and Queensland Parks and Wildlife Service, with cooperation from the Wet Tropics Management Authority for nature conservation. The 2012 species account lacked sufficient information to assess conservation status. Surveys of this spider’s distribution and leaf-litter habitat would complement rainforest management and inform species-specific conservation.
