ETYMOLOGY: The specific name is a patronym in honor of Ludo Collingwood, a world-renowned painter of rainforest creatures occurring in the Wet Tropics Bioregion.
DIAGNOSIS: The male of this species is distinguished by unique modifications of the palpal embolic region, which is enlarged and consists of a stout lateral process that curves around the distal end toward the prolateral aspect (fig. 52E). The distal tip is also curved backward and pointed (fig. 52A, B). The female epyginal region consists of a small triangular projection posterior to the epigynal atrium depression with the sclerotization heavier in the posterior portion, forming a U-shape. A narrow ‘‘necklike’’ structure is evident halfway along convoluted duct, but is not very distinct (figs. 51I, 52F).
MALE (PBI_OON 5890, figs. 51A–C, G– H, 52A–E). Total length 1.70. CEPHALO- THORAX: Carapacepale orange, 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 with slightly sclerotized triangular projections, surface of elevated portion of pars cephalica smooth, sides finely reticulate. Clypeusmargin unmodified, curved downward in front view, low, ALE separated from edge of carapace by less than their radius; setae light. Eyes:ALE largest, ALE circular, PME oval, PLE oval; posterior eye row straight from above; ALE touching, ALE-PLE touching. Sternumas long as wide, pale orange, uniform; setae light, evenly scattered. Chelicerae, endites, and labium orange-brown. Chelicerae straight, anterior face unmodified, fang normal, basal process small and knoblike; promargin with one or two larger denticles; setae light. Labium elongated hexagon, not fused to sternum, anterior margin indented at middle, much more heavily sclerotized than sternum; with six or more setae on anterior margin. Endites distally not excavated, anteromedian tip with one strong, toothlike projection, much more heavily sclerotized than sternum. ABDOMEN: Ovoid; dorsum soft portions white. 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 smooth, sides smooth. Epigastric scutum small lateral sclerites absent. Postepigastric scutum pale orange, covering about 2/3 of abdominal length. Dorsum, epigastric area, and postepigastric area setae light. LEGS: Pale yellow, without color pattern; patella plus tibia I shorter than carapace. Leg spination: femora: I p0-1-2; II p0-0-1; 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, without posteriorly rounded lateral dilation; patella shorter than femur; cymbium dark red-brown; bulb dark red-brown, 1 to 1.5 times as long as cymbium, stout; embolic region, enlarged and clublike, stout lateral process curved around distal end toward prolateral aspect (fig. 52E), distal tip curved backward and pointed (fig. 52A, B). FEMALE (PBI_OON 5594, figs. 51D–F, I, 52F). Total length 1.95. CEPHALOTHO- RAX: Carapacepars cephalica slightly elevated in lateral view. Sternumlonger than wide. Chelicerae, endites, and labium pale orange. ABDOMEN: 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 near as long as carapace. Leg spination: femora: I p0-1-1; II p0-0-1; tibiae: I, II p2-2- 0; v2-2-0; metatarsi: I, II p1-1-0; v1-1-0; 2 smaller spinelike setae on retrolateral aspect of femora I and II. GENITALIA: Ventral view: epigynal atrium with small posterior triangular projection, sclerotization heavier in posterior portion, forming U-shaped depression, narrow ‘‘necklike’’ indents evident halfway along convoluted duct; convoluted duct thicker than apodemes (fig. 52F).
