Type material. AUSTRALIA: Queensland: male holotype, Mount Glorious, 630 m, 29 May 1973, A. Chew (QMB S813) . Paratypes: 1 male, Mount Glorious (GM91), pitfall trap, rainforest, 630 m, 26 June–18 November 1978, G. & S. Monteith (QMB S815) ; 1 male, same data except (GM45), 6 August–12 November 1975 (QMB S814) .

Other material examined. Australia: Queensland: 1 male, D’Aguilar National Park, Mount Glorious, 27°19’40”S, 152°45’13”E, pitfall trap, 687 m, 15–20 October 2014, Entomological Society of Queensland Bugcatch (QMB S111535 DNA) .

Diagnosis. Males of Namea excavans can be distinguished from those of all other described congeners except N. dahmsi by the morphology of the palpal tibia, which has multiple proximal and/or medial macrosetae on the retroventral margin (Fig. 17b; see also Rix et al. 2020, figs 187, 188). Males can be further distinguished from those of N. dahmsi by the long, reflexed and whip-like embolus (Fig. 17b; cf. Fig. 21b; see also Rix et al. 2020, figs 187, 188).

Females are unknown.

Distribution. Namea excavans is endemic to the D’Aguilar Range, where it is known only from rainforest at Mount Glorious (Rix et al. 2020) (Fig. 2).

Remarks. This species is extremely rare, and currently known from only a handful of male specimens. Nothing is known of its biology or life history, other than that males appear to be active in winter or spring.
