Orchestina debakkeri new species

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 .
