Etymology. The species is dedicated to the late Valerie Todd Davies, a pioneering Australian arachnologist; name in genitive case.

Diagnosis. Micropoda daviesae spec. nov. may be recognised by the following combination of characters: Males (Figs 47–52): 1. RTA proximally arising from tibia, with 2 lateral apices, a large medial tooth and a small additional tooth (Fig. 51), 2. Embolus arising from tegulum at 5-o’clock-position, filiform and apically coiled and 3. Embolic apophysis arising from embolus in 10-o’clock-position, running parallel to and with similar width of embolus up to their tip. Females (Figs 53–57): 1. Lateral lobes extending postero-laterally and running latero-anteriorly in anterior half, 2. Glandular appendages situated at the end of the first winding of the internal duct system and 3. Internal duct system with 1 big loop posteriorly and 4 subsequent turns.
