Diagnosis
Males of A. cassowariensis sp. nov. can be distinguished from all species for which males are known except A. calida sp. nov., A. carina, A. harmoniosa sp. nov., A. robertsorum, and A. tropicana sp. nov. by a moderate to large body size (carapace length>4.0 mm), and the presence of a long embolus (embolus length / bulb length>1.5) that is thin, with a sharp bend near its base before a relatively straight distal section (Fig. 59L–M). Males of A. cassowariensis can be distinguished from those of A. carina, A. harmoniosa, and A. robertsorum by the presence of a shorter embolus (embolus length / bulb length <2) (Fig. 59L–M; cf. Figs 57, 60, 61). Males of A. cassowariensis can be distinguished from those of A. tropicana by the presence of thinner leg and pedipalp segments (e.g., metatarsus I length / width>4) (Fig. 59J–K, N–Q; cf. Fig. 62). Males of A. cassowariensis can be distinguished from those of A. calida by the presence of a less elongate palp tibia (palp tibia length /width ~ 2.3; cf. 2.6 in A. calida) (Fig. 59J–K; cf. Fig. 56).
Females of A. cassowariensis sp. nov. are unknown.
Etymology
The specific epithet ‘ cassowariensis ’ references the known distribution of this species in the Cassowary Coast region of tropical Queensland.

Distribution and natural history
Aname cassowariensis sp. nov. occurs in northern Queensland, in the Wet Tropics bioregion, with specimens known from two lowland locations, a northern location near Mission Beach, and a southern location near Paluma (Fig. 9). The form of burrows constructed by spiders of this species is unknown, but is likely to be similar to that of other robertsorum -complex species (Fig. 9).
