The female epigynal region is similar to that of  I. comicus, sp. nov., but differs in the smaller width of the epigynal atrium opening, which is more jelly-bean shaped, and the faint but visible lines running down each side of the convoluted duct (figs. 27I, 28E).  MALE (PBI_OON 22001, figs. 27A–C, G, H, 28A–D). Total length 1.36. CEPHALO- THORAX: Carapacepale orange, broadly oval in dorsal view, pars cephalica slightly elevated in lateral view, anteriorly narrowed to 0.49 times its maximum width or less, anterolateral corners without extension or projections, surface of elevated portion of pars cephalica finely reticulate, sides finely reticulate. Clypeusmargin unmodified, straight 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. Sternumlonger than wide, pale orange, uniform; setae light, evenly scattered. Chelicerae, endites, and labium pale orange. Chelicerae straight, anterior face unmodified; fang shape normal, with prominent medial process; setae light; promargin with one larger denticle. Labium elongated hexagon, not fused to sternum, anterior margin indented at middle, same as sternum in sclerotization. Endites anteromedian tip with one strong, toothlike projection, same as sternum in sclerotization. ABDOMEN: Ovoid; dorsum soft portions white. Book lung covers round. Dorsal scutum pale orange, 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 absent. Postepigastric scutum pale Map 6.

LEGS: White, without color pattern; patella plus tibia I nearly as long as 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. GEN- ITALIA: Palp proximal segments dark redbrown; embolus light; femur one to two times as long as trochanter, without posteriorly rounded lateral dilation; patella shorter than femur; cymbium dark redbrown, without distal patch of setae; bulb dark red-brown, more than two times as long as cymbium, stout; embolic region obtusely bent, slightly bent back toward cymbium, distal tip curved anteriorly, darkened apparent embolus opening positioned distal to thin conductor. FEMALE (PBI_OON 25753, figs. 27 D–F, I, 28E). Total length 1.50. CEPHALOTHO- RAX: Dorsal scutum covering 1/2 to 3/4 of abdomen, between 1/4 and 1/2 abdomen width. Postepigastric scutum widely hexagonal, only around epigastric furrow. LEGS: Yellow; 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: Ventral view: epigynal atrium slightly wider than high, jelly-bean shaped, lateral edges round- ed, heavily sclerotized processes absent; convoluted duct thicker than apodemes, faint but visible lines running down each side of the convoluted duct (figs. 27I, 28E).  OTHER MATERIAL EXAMINED: AUS- TRALIA:  Queensland: Bellenden Ker Range,  0.5 kmS Cabletower 7, rainforest,  500 m, 17.26667 °S, 145.85000 °E,  Nov. 1–7, 1981(EARTHWATCH/ Qld Museum, QM S27626, PBI_OON 25930), 1 ³;  Bellenden Ker Range, cable tower 3, rainforest, leaf litter,  1054 m, 17.26667 °S, 145.85000 °E,  Oct. 17–24, 1981(EARTHWATCH/ Qld Museum, QM S27896, PBI_OON 22156), 2 ³, 1 ♀;  Bellenden Ker Range, Centre Peak Summit, rainforest, leaf litter,  1560 m, 17.26667 °S, 145.85000 °E,  Oct. 23, 1980( G.
