Diagnosis

Males of A. carina can be distinguished from all species for which males are known except A. calida sp. nov., A. cassowariensis sp. nov., 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. 57L–M). Males of A. carina can be distinguished from those of A. calida, A. cassowariensis, and A. tropicana by the presence of a longer embolus (embolus length / bulb length>2) (Fig. 57L– M; cf. Figs 56, 59, 62). Males of A. carina can be distinguished from those of A. harmoniosa and A. robertsorum by the presence of a distally-positioned tibial spur (distance to spur/ tibia length ~0.71) (Fig. 57P; cf. Figs 60–61).

Females of A. carina can be distinguished from all species for which females are known except A. tropicana sp. nov. by the presence of bicoloured legs, with darker femurs and lighter distal segments, and spermathecae with two vesicles, with relatively long and straight lateral vesicles (lateral vesicle length / genitalia width>0.25) that are laterally angled, and medial vesicles that are shorter or about equal in length to the lateral vesicles, and curve gradually from a medial to a lateral angle (Fig. 58J–L). Females of A. carina can be distinguished from those of A. tropicana by the presence of spermathecae with longer medial vesicles (medial vesicle length/ lateral vesicle length ~ 1; cf. ~ 0.7 in A. tropicana) (Fig. 58L; cf. Fig. 63).

Distribution and natural history

Aname carina occurs in northern Queensland, in the Einasleigh Uplands and Wet Tropics bioregions, and is known from two areas, in and around the Forty Mile Scrub National Park, and further east near the town of Herberton (Fig. 9). It constructs an open, silk-lined burrow without silk outside of the entrance, often at an angle, and with a hidden secondary ‘wishbone’ entrance (Fig. 9).

Remarks

Two disjunct populations of this species are known, one near Forty Mile Scrub (the type locality), and another closer to the coast, near Herberton. Despite differences in the average size of individuals from these two populations, both genitalic morphology and genetics (COI average pairwise divergence of 5.26%) strongly indicate that they are the same species.
