Diagnosis. Males of Namea brisbanensis can be distinguished from those of all other described congeners except N. gowardae by the morphology of tibia I, which has the standard brisbanensis -complex prolateral/ventral spination pattern (2pd–2pv–3v), plus a short macroseta v1 and largely asetose proventral ‘tibial bald zone’ between macrosetae pv1 and pv2 (Fig. 18a; cf. Figs 42, 44). Males can be further distinguished from those of N. gowardae by the broadly pyriform shape of the palpal bulb (Fig. 18b; cf. Figs 45–47), the broader profile of tibia I (Fig. 18a; cf. Fig. 44; see also Rix et al. 2020, fig. 25), and the more strongly concave ventro-distal excavation anterior to macroseta v1 (Fig. 18a; cf. Fig. 44; see also Rix et al. 2020, fig. 25). Females are very similar in general appearance to those of N. gowardae (Fig. 4; cf. Fig. 5), but can be distinguished by the shape of the receptacula, which are longer, ‘sausage-shaped’ and are each without a clearly defined fundus (Fig. 18c; cf. Fig. 19c; see also Raven 1984, fig. 104). Distribution. Namea brisbanensis is an unusually widespread species, recorded from numerous low to mid-elevation rainforest sites in south-eastern Queensland, from the Conondale National Park south to near the Queensland / New South Wales border (Rix et al. 2020). On the D’Aguilar Range it is a common species, known from Brookfield (the type locality), Gold Creek, Enoggera Reservoir, Mount Coot-tha, Mount Nebo and Mount Mee (Fig. 2). Remarks. This species is one of three Namea on the D’Aguilar Range which have a broader distribution in south-eastern Queensland. The spiders are usually the most abundant of Namea species on the range, where their open burrows can be found in rainforest, wet sclerophyll and riparian habitats. At some sites, N. brisbanensis is syntopic with N. nigritarsus and N. salanitri, and in the Maiala region of Mount Glorious it is seemingly replaced by populations of N. gowardae, the latter of which can only be properly (but nonetheless easily) distinguished upon close examination of the male or female genitalia, or by using molecular sequencing methods. Males, like most other members of the brisbanensis -complex, have densely setose gold abdomens and highly reflective gold setae on the leg femora (e.g. see Rix et al. 2020, fig. 10), and appear to be active during summer and autumn, presumably in response to seasonal rain events.
