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.
