Figures 206–221, 606  
 TYPE: Holotype Male: Ghana, Kakum forest, primary forest, canopy, 5.33333°, -1.38333°, Nov. 25, 2005, De Bakker D., Jocqué R. & Baert L. (MRAC 228939 PBI _OON 33854).   
ETYMOLOGY: The species is a patronym in honor of Domir Debakker one of the collectors of the type material.  
 DIAGNOSIS: The male of O. debakkeri is recognized by the endites having a beak-shaped tip (Figs. 209, 210), a conspicuous serrula (Figs. 216–218) and the prolateral side of the bulb with one club shaped seta (Fig. 220). The female is distinguished from most species (except O. probosciformis) by the combination of a trunk-shaped abdominal extension, an eye-shaped genital area with rounded, iris-shaped central plate (ARe) with small, triangular, ventral sclerite and the presence of a small posterior receptaculum.   
 MALE (PBI_OON_0033854). Total length 1.02. CEPHALOTHORAX: Carapace (Figs. 206–208, 210) yellow, elongate oval in dorsal view (CW/CL ≈ 0.65), pars cephalica strongly elevated in lateral view, anteriorly narrowed to between 0.5 and 0.75 times its maximum width. Clypeus sloping forward in lateral view. Eyes: eye interdistances ALE-PME: touching, PME circular;PLE-PME separated by less than PME radius. Sternum as long as wide, yellow, anterior margin unmodified, posterior margin extending posteriorly beyond anterior edges of coxae IV as single extension; setae abundant, dark, evenly scattered. Mouthparts: Chelicerae, endites and labium pale orange. Chelicerae slightly divergent, posterior side with two pairs of long setae; retromargin without teeth; setae dark; paturon laminate groove present. Labium (Figs. 214–215) rectangular, anterior margin not indented at middle, same as sternum in sclerotization, anterior part depressed: margins of posterior half sclerotized; with 6 or more setae on anterior margin, with 4 setae half way lateral margin on each side. Endites (Figs. 209, 214–218) serrula present in single row, sinuous; anteromedian tip with one strong, tooth-like projection, anterior part more strongly sclerotized than sternum. ABDOMEN (Figs. 206, 208): ovoid; dorsum soft portions pale, with gray netlike pattern. Pedicel unmodified, scutum absent, but abdomen extending anteriad of pedicel. Postepigastric area setae needle-like. LEGS: yellow; LEGS: patella plus tibia I shorter than carapace (TL/CL ≈ 0,77); tarsus II superior claws with four teeth on lateral surface of proclaw, four teeth on lateral surface of retroclaw; tarsus IV superior claws with four teeth on lateral surface of proclaw, four teeth on lateral surface of retroclaw. GENITALIA: Palp (Figs. 211–213, 219–221) trochanter minute, unmodified; patella without prolateral row of ridges; tibia fusiform, larger than femur; cymbium yellow, without distal patch of setae; bulb yellow, stout, tapering apically, prolateral side with one club shaped seta (Fig. 220); embolus dark.   
 FEMALE (PBI_OON_0033854). Total length 1.16. Further description as O. probosciformis.
