TYPES: AUSTRALIA: Queensland: Male holotype and female allotype from Tam O’Shanter National Park, Licuala Fan Palm walk, 17.915 ° S, 146.06833 ° E (7 May 2009, K. Edward and P. Cullen), deposited in QM (³ holotype: QM S95978 View Materials , PBI _ OON 00005545; ♀ allotype: QM S95979 View Materials , PBI _ OON 00005624) GoogleMaps   .

ETYMOLOGY: The specific epithet is a patronym in honor of Kyran Staunton, the collector of this species and many other interesting invertebrates of the Wet Tropics.

DIAGNOSIS: Male similar to that of I. monteithi   , sp. nov., and I. barratus   , sp. nov., but differs in a rounded basal bump on the fang (fig. 63C, D), and the palp has a stouter embolic region (fig. 63 A, B). The female epigynal region of this species has a heavily sclerotized round epigynal atrium with a very small triangular process overhanging the anterior section (fig. 63F).

MALE (PBI_OON 5545, figs. 62A–C, G– H, 63A–E). Total length 1.48. CEPHALO- THORAX: Carapace yellow-brown, broadly oval in dorsal view, pars cephalica strongly elevated in lateral view, anteriorly narrowed to between 0.5 and 0.75 times its maximum width, anterolateral corners without extension or projections, surface of elevated portion of pars cephalica finely reticulate, sides strongly reticulate. Clypeus margin unmodified, curved downward in front view, low, ALE separated from edge of carapace by less than their radius; setae dark. Eyes: ALE largest, ALE circular, PME circular, PLE oval; posterior eye row procurved from above; ALE touching, ALE-PLE touching. Sternum longer than wide, pale orange, uniform; setae dark, evenly scattered. Chelicerae, endites, and labium pale orange. Chelicerae straight, anterior face unmodified; promargin with one slightly larger denticle; fang shape normal, with small basal process; setae dark. Labium elongated hexagon, not fused to sternum, anterior margin indented at middle, same as sternum in sclerotization; with six or more setae on anterior margin. Endites distally not excavated, anteromedian tip with one strong, toothlike projection, same as sternum in sclerotization. ABDO- MEN: Ovoid; dorsum soft portions white. Book lung covers elliptical. Dorsal scutum yellow-brown, covering more than 3/4 of abdomen, more than 1/2 to most of abdomen width, middle surface smooth, sides smooth. Epigastric scutum small lateral sclerites present. Postepigastric scutum pale orange, covering about 2/3 of abdominal length. Dorsum, epigastric area, and postepigastric area setae dark. LEGS: Orange, without color pattern; patella plus tibia I shorter than carapace. Leg spination: femora: I p0-2-0; II p0-1-0; tibiae: I, II p2-2-0; v2-2-0; metatarsi: I, II p1-1-0; v1-1-0. GENITALIA: Palp proximal segments dark red-brown; embolus dark; femur shorter than trochanter; patella about as long as femur; cymbium dark redbrown; bulb dark red-brown, more than two times as long as cymbium, stout; embolic region simple, without enlarged or complex processes, stout, distal edge straight, small subdistal transparent membranous structure on dorsal aspect (fig. 63A, B).

FEMALE (PBI_OON 5624, figs. 62D–F, I, 63F). Total length 1.68. CEPHALOTHO- RAX: Carapace pars cephalica slightly elevated in lateral view, anteriorly narrowed to 0.49 times its maximum width or less. Eyes: posterior eye row straight from above. ABDOMEN: Dorsal scutum covering 1/2 to 3/4 of abdomen, between 1/4 and 1/2 abdomen width. Postepigastric scutum widely hexagonal, covering about 1/3 of the abdominal length. LEGS: Leg spination: femora: I p0-2-0; II p0-1-0; tibiae: I, II p2- 2-0; v2-2-0; metatarsi: I, II p1-1-0; v1-1-0. GENITALIA: Ventral view: epigynal atrium circular, small triangular process over anterior edge, heavily sclerotized around epigynal atrium, lateral edges with weaker sclerotization; convoluted duct tightly coiled, stout, thicker than apodemes (figs. 62I, 63F).
