Diagnosis

Males of A. consuelo sp. nov. can be distinguished from all species for which males are known by a moderate to large body size (carapace length>4.0 mm), the presence of a very long embolus (embolus length / bulb length> 2.5), a very long asetose depression on the palp tibia (depression length / palp tibia length ~ 0.8), and a very long tibial megaspine (megaspine length / tibia length>0.3) (Fig. 108J–Q).

Females of A. consuelo sp. nov. can be distinguished from all species for which females are known by the presence of spermathecae with two vesicles, with highly elongate, relatively straight lateral vesicles (lateral vesicle length / width ~ 5.9), and short, medially-angled medial vesicles (Fig. 109L).

Etymology

The specific epithet ‘ consuelo ’ is a noun in apposition, referencing the only known collection locality of this species, on the Consuelo Tableland, within Carnarvon National Park, in central Queensland.
