Holotype
AUSTRALIA: South Australia: ♂, Quinyambie Station, 7.5 km SSE. of Coonanna Bore, 29°54’39”S, 140°47’42”E, open shrubland, Acacia ligulata over Brassica & Crotalaria eremaea, 27 October–1 November 2008, Waterhouse Survey (SAM NN30453).
Paratypes
AUSTRALIA: South Australia: 2 ♂, collected with holotype (SAM NN29034, NN30452).
Diagnosis
Males of Kwonkan procul differ from K. currycomboides and K. linnaei by the lack of cuspules on coxae III and IV (Figure 20); from K. eboracum, K. goongarriensis, K. moriartii and K. silvestris by the more elongate pedipalpal tibia (Figures 29–31); from K. dissitus and K. seductus by the more acutely angled ventral spur and megaspine on tibia I (Figures 33, 34), and the thinner, straighter embolus (Figures 29–31) as opposed to the thicker gradually-curving emboli of those species.

Description (male holotype, SAM NN30453)
Medium-large anamid spider (total body length 13.5).
Colour (in alcohol): Carapace dark red-brown with darker markings in cephalic region (Figure 19); legs brown, some segments with longitudinal pale stripes, tarsi paler; chelicerae uniformly dark red-brown (Figure 19); abdomen dorsally grey-brown (Figure 24), and ventrally pale creamy-yellow (Figure 25).
Cephalothorax: Carapace (Figure 19) 1.19 x longer than broad; densely pilose; silver setae present; with brown bristles dorsally; clypeal edge straight. Fovea (Figure 22) slightly procurved. Eyes (Figure 21): on distinct mound; from above, anterior eye row slightly procurved, posterior eye row nearly straight; AME about same size as ALE; ALE and AME the largest; PME smallest; eye group length 0.5, width 1.1. Chelicerae (Figure 19) densely setose with black bristles and silver setae; rastellum absent; promargin of tooth row with 10 teeth, retromargin with 4 teeth. Labium (Figure 23) fused to sternum, without cuspules. Maxillae (Figure 27) with ca. 110 cuspules; located on the basal half. Maxillae noticeably darker than coxae I–IV (Figure 20). Sternum (Figure 23): oval; 1.28 x longer than broad; bristles sparsely over entire surface; with 3 pairs of sigilla (Figure 26), each pair increasing in size from anterior to posterior; posterior pair elongate and slightly curved or anterior pair located near edge of sternum.
Pedipalp (Figures 28–31): Tibia cylindrical, narrow, asetose depression absent; tarsus short; densely setose; bulb ovoid; embolus slightly longer than bulb and gently curved.
Legs: Coxal cuspules absent (Figure 20). Tibia I with large megaspur (Figures 33, 34); TIL/TID 4.24; TIS/TIL 0.61; TISH/TID 0.47; metatarsus incrassate; MIL/MID 7.33; MIPEL/MIL 0.40; scopula present on all tarsi, absent on metatarsi, trichobothria: tibia with numerous trichobothria in 2 rows, metatarsi with several trichobothria; tarsi with numerous trichobothria, claws: with 2 rows of teeth; claw tufts absent. Dimensions (mm): Femur I 6.8; tibia I 4.9; metatarsus I 5.5; II 6.5; III 5.9; IV 7.6.
Abdomen (Figures 24, 25): 1.53 x longer than broad; densely pilose with bristles. Spinnerets: AMS short; ALS long.
Dimensions (mm): Total body length (with chelicerae, but excluding spinnerets) 13.5. Carapace length 6.4; width 5.4. Sternum length 3.2; width 2.5. Abdomen length 6.1; width 4.0.
Variation: N= 2; carapace length: min 6.0; max 6.4; width: min 5.0; max 5.6; femur I length: min 6.3; max 6.8; metatarsus I length: min 4.8, max 5.5; femur IV length: min 6.4; max 7.8.
Remarks
Kwonkan procul has been collected from a single location in north-eastern South Australia (Figure 1), which is located in the Simpson Strzelecki Dunefields bioregion.
Etymology
The species epithet is an adverb that refer to the presence of this species in north-eastern South Australia (procul, Latin, far but within sight) (Brown, 1956).
