Etymology.
The name reflects the
Queensland
origin of the
type
material and is to be treated as a noun in apposition.
Diagnosis.
It differs from the
type
species by the shorter and wider shape of the cymbium, the presence of a large bulge on the ventral surface of the tegulum and a small hooked posterior lobe. A mottled brown pattern is found on the dorsal surface of the abdomen rather than the distinctive pattern of large dark spots on the dorsal abdomen found for
F. maculata
. The lateral position and the shape of the embolus (Figs 75–77) and long L3 clearly show that this is a species of
Frewena
.
Description.
Male
: Cephalothorax mid to dark orange with scattered pennate grey hairs over dorsal and lateral surfaces. Relatively longer cephalothorax with a steeper posterior slope than in
F. maculatus
. Integument surrounding ALE, PME and PLE dark brown with scattered grey hairs. Clypeus narrow, with a sparse grey fringe. Chelicerae not geniculate, medium brown. A single very small prolateral tooth and a single small sharp retrolateral tooth are found on the distal edge of the paturon. Endites white, grading to light brown, labium dark brown. Sternum mid-brown. Dorsal abdomen light brown, with darker, lace-like patterning. Large mid-brown sclerite-like shape apparent under the surface patterning. Spinnerets pale yellow and black. Ventral abdomen same colour as dorsal surface. Legs mid-brown, without stripes or markings. L3 much longer than remainder.
Palp
: brown, tibia with a single long narrow apophysis. Patella with a long dorsal fringe of long thick hairs. Tegulum very broad with a proximal lobe, a projection on the distal margin and large ventrolateral swelling. The origin of the embolus lateral, forming a tapering single anticlockwise spiral then moving distally across the surface of the cingulum. Dimensions (

Female
: Unknown.
Distribution and Biology
. Known only from the
type
locality, in litter (
Fig. 60
). As a consequence, IUCN Red List Category DD. Because of its limited known range it may be at risk through climate change or habitat loss.
