Diagnosis

sp. nov.
in the more rounded epigynal septum and the block-like spermathecae (Fig. 1f). Males unknown.

Abdomen dorsally with white narrow dagger-like area anteriorly, with fine black borders, converging and continuing at mid-length. Abdomen dorsally generally light grey (Fig. 1a); two narrow lines from long “V alongside median “V; two broad irregular bands for length of abdomen, lateral margins mottled. Legs not banded.

Labium
. About as long as wide with symmetrical sinusoidal ridge basally at constriction, ridge more sclerotised on outer edges.
Maxillae
. Short, narrower basally but cylindrical, with groove extending from point of labium ridge parallel to posterior edge to

Sternum
. Cordate with intercoxal corners. Trochanters deeply notched.
Scopula
. All leg tarsi with
scopula
of long setae, not so dense as to obscure cuticle, that on IV divided with band of 2 lines of setae. Metatarsi, full for I, II, thinner basally; distal two-thirds of III, IV and in 3 bands, pro- and retroventral and ventral. None on palp.
