Diagnosis

Males of A. cudmore sp. nov. can be distinguished from all species for which males are known except A. savannella sp. nov. by a small body size (carapace length <4.0 mm), the presence of a short embolus (embolus length / bulb length <1.5), a relatively thick metatarsus I (metatarsus I length / width <4), and the absence of thorn-like setae on the retrolateral palp tibia (Fig. 103A–Q). Males of A. cudmore can be distinguished from those of A. savannella by the presence of a thicker metatarsus I (metatarsus I length / width ~3.2; cf. ~ 3.9 in A. savannella) (Fig. 103Q; cf. Fig. 104).

Females of A. cudmore sp. nov. are unknown.

Etymology

The specific epithet ‘ cudmore ’ is a noun in apposition, referencing the only known collection locality of this species, in Cudmore National Park at the northern end of the Drummond Range in central Queensland.

Distribution and natural history

Aname cudmore sp. nov. occurs in central Queensland, in the Desert Uplands bioregion, in the Cudmore Resources Reserve (Fig. 13). The form of burrows constructed by spiders of this species is unknown.
