Figs 61–62 View FIGURE 61 View FIGURE 62

Diagnosis. Males are very similar in the palpal bulb and RTA to those of K. gracilis , but differ from those of K. gracilis and all other known species, except Xis. jandateae sp. nov., in having a patellar cone prolaterally on the palp ( Fig. 61b View FIGURE 61 ).

Etymology. The species epithet is a noun in apposition from the type locality.

Type Material. Western Australia: male holotype, 40 km N. of Johnston Lakes {32°09’S 120°45’E} (S. of Coolgardie), 1 Jan 1977, A.M. Douglas, M.J. Douglas, ( ABFC), WAM98 About WAM GoogleMaps /798.

Paratype. 1 fem. same data as holotype, WAM 98 About WAM GoogleMaps /799.

Description. Male, holotype WAM98/798

Carapace 4.56 long, 3.36 wide. Opisthosoma 4.16 long, 2.40 wide. Total length, 8.7.

Colour: Carapace with two moderately dark shell-like areas laterally; opisthosoma dorsally laterally pallid mottled lightly with distinct dark median stripe with 2 lateral ostiate branches; ventrally none, pallid; femora with weakly discernible mottling. Eyes: All similar, small; ALE clearly smallest. Posterior row eyes more or less overlapping; PME and PLE inner edges well separated. Legs very long. Spines: Femora pv1 only on I, II; tibia I, II p2d1r2 on I, II.

Palp: Patella with distinct retrolateral conical process; dorsally with distal point interlocking with sclerotised notch on basal tibia; cymbial hairs all similar, but hairs very long basally on cymbium; retrobasally with a distinct groove for basal half; probasal edge extended laterally with distinctly squared edge forming rounded lobe; apex of ventral lobe blunt, triangular; dorsal lobe a wide, recurved hooked plate; RTA distal; short, directed laterally; two plates sandwiching unsclerotised zone; base of ventral lobe darkly sclerotised conical process; ventral lobe long, triangular, dorsal lobe a wide, recurved hooked plate; embolus central, directed basally.

Female WAM 98/799

Scopula on tibia I for full ventral for distal 0.6 of I, two narrow lateral bands for ca. 0.5 of II, absent on III, IV. Epigyne: Median septum wide Y- or grail-shaped lateral ridges, short median septum not to posterior edge.
