Diagnosis.
Males of
Namea salanitri
can be distinguished from those of all other described congeners by the morphology of the embolus, which is short, strongly curved and positioned sub-terminally on the palpal bulb (
Fig. 20b
; see also
Rix
et al.
2020
, figs 78–80).
Females are similar in general appearance to those of other large species in the
brisbanensis
complex (
Fig. 6
; cf.
Figs 4, 5
), but can be distinguished by the short receptacula (
Fig. 20c
; cf.
Figs 18c, 19c
), the presence of unusual, ear-like epigastric lobes (
Fig. 20c
; see also
Raven 1984
, fig. 129), and lighter, honey-red leg femora in life (
Fig. 6
; cf.
Figs 4, 5
).
Distribution.
Namea salanitri
is a widespread species in south-eastern
Queensland
, where it has been recorded from scattered mid- to high elevation rainforest sites to the north, west and south-west of Brisbane (
Rix
et al.
2020
). On the D’Aguilar Range it is known from Mount Mee (the
type
locality) and Mount Glorious (
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 not abundant on the range, and are restricted to rainforest habitats. At some sites,
N. salanitri
is syntopic with
N. brisbanensis
and
N. nigritarsus
, although both males and females of
N. salanitri
are easy to distinguish from other congeners morphologically. Little is known of its biology or life history, other than that males appear to be active in winter and spring.
