TYPES: AUSTRALIA: Queensland: Male holotype, female allotype and 1 male and 1 female paratypes from Bellenden Ker Range , cable tower 3, 17.26667 ° S, 145.85000 ° E, 1054 m (25–31 Oct 1981, EARTHWATCH/ Qld Museum), deposited in QM (³ holotype: QM S27906 View Materials , PBI _ OON 22150 View Materials ; ♀ allotype and 1 ³, 1 ♀ paratype: QM S27906 View Materials , PBI _ OON 5610) GoogleMaps   .

ETYMOLOGY: The specific name is a patronym in honor of Geof Monteith, in recognition of his enormous contribution to entomology and numerous collections within the Wet Tropics Bioregion.

DIAGNOSIS: This species is similar to I. barratus   , sp. nov., but can be identified by a rounded disc-shaped basal process on the male cheliceral fang (fig. 59D), a distal concavity on the distal edge of the male palp (fig. 59A, B), the lack of a clear epigynal atrium or sclerotized structure in the female epigynal region, and a long dorsal scute covering 2/3 of the female abdomen.

MALE (PBI_ OON 22150 View Materials , fig. 58 A–C, G, H; paratype (PBI_ OON 05633 View Materials ), fig. 59A–E). Total length 1.43. CEPHALOTHORAX: Carapace pale orange to live green, 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 strongly 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 oval, 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 slightly divergent, anterior face unmodified; promargin with one slightly larger denticle; fang shape normal, with prominent disc-shaped basal process; setae dark. Labium elongated hexagon, not fused to sternum, anterior margin indented at middle, slightly stronger sclerotization than sternum; with six or more setae on anterior margin. Endites distally not excavated, anteromedian tip with one strong, toothlike projection, stronger sclerotization than sternum. ABDOMEN: Ovoid; dorsum soft portions pale orange. Book lung covers elliptical. Dorsal scutum pale orange, covering more than 3/4 of abdomen, more than 1/2 to most of abdomen width, middle surface finely reticulate, sides finely reticulate. Epigastric scutum small lateral sclerites absent. Postepigastric scutum pale orange, covering about 2/3 of abdominal length. Dorsum, epigastric area, and postepigastric area setae dark. LEGS: Pale 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, shaped like elephant’s trunk, stout, distal edge with concavity (fig. 59A, B).

FEMALE (PBI_OON 5610, fig. 58D–F, I; paratype (PBI_ OON 05622 View Materials ), fig. 59F). Total length 1.54. CEPHALOTHORAX: Carapace pars cephalica slightly elevated in lateral view, anteriorly narrowed to 0.49 times its maximum width or less. ABDOMEN: Epigastric scutum small lateral sclerites present. Postepigastric scutum widely hexagonal, only around epigastric furrow. LEGS: Orange. 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 region very simple, no discerning epigynal atrium, without sclerotized projections; convoluted duct very dark, thicker than apodemes (fig. 59F).
