Etymology.
The specific epithet refers to the
Banyjima
language indigenous to the
type
locality. This name is to be treated as a noun in apposition.
Diagnosis.
Females of
K. banyjima
sp. nov.
are most similar to
K. burbidgei
but can be distinguished by the absence of a distinct m-shaped hood over the copulatory openings. Instead, they have a small, posteriorly-located depression with an anterior m-shaped margin. Additionally, the copulatory ducts are highly sclerotised and very dark and are easily observed in ventral view (
Figs 33–34
). Males are unknown.
Description.
Female (
holotype
):
Colour.
Dorsal shield of prosoma yellow-brown, with slightly darker marks laterally and medially; sternum pale yellow; chelicerae yellow-brown with darker infuscations anteriorly and laterally; maxillae pale yellowbrown; labium pale brown, lightening distally; opisthosoma dorsally yellow-brown with reddish-brown and dark setae, black horizontal w-shaped marks medially, black flecks laterally; ventrally pale yellow-brown; legs with segments clearly annulated, but annulations do not completely encircle femora, legs darkening distally at tibiae; annulations lighter in centres.
Prosoma.
0.91 times longer than broad; clypeus 0.13 high.
Eyes.
