Figs 13–14, 51–58, 87; Table 4
Diagnosis
Male differ from those of all other species by the short and thin paraembolic apophysis, the presence of a ventral retrolateral keel with small retrolateral striae below and the presence of retrolateral tegular apophysis. Share with those of S. benedettii, S. modesta and S. wayana sp. nov. the embolus and paraembolic apophysis pointing forward (Figs 51–55). Females unknown.
Etymology
The name is in honor of Joep and Marijke Moonen, owners of the Emerald Jungle Village in French Guiana.

Description
Male (holoype IBSP 168510)
COLOR (in alcohol). Carapace, legs and chelicerae dark brown, sternum, labium brown, abdomen light brown (Figs 13–14).
MEASUREMENTS. Total length: 20.31. Chelicerae basal segment: length 3.95. Carapace slightly elongated, covered with long and fine bristles: length 8.68, width 7.36. Abdomen: length 11.32. Clypeus absent. Eye tubercle slightly elevated, sub-rectangular: length 0.73, width 1.71. Anterior eye row slightly procurved, posterior slightly recurved. Eyes and interdistances: AME 0.41, ALE 0.33, PME 0.28, PLE 0.29, AME– AME 0.15, AME–ALE 0.10, ALE–ALE 1.15, PME–PME 0.88, PME–PLE 0.16, PLE–PLE 1.37, AME–PME 0.05 ALE–PLE 0.09. Thoracic fovea short narrow, deep: width 0.97. Chelicerae basal segment with 11 well-developed teeth on furrow promargin and a group of ca 25 small teeth on proximal area of furrow. Intercheliceral tumescence absent. Maxillae with ca 100 cuspules, located on anterior inner corner. Labium trapezoidal: length 0.96, width 1.41, with ca 200 cuspules. Sternum slightly oval: length 4.01, width 3.88; with three pairs of sigilla, posterior ones longer than the others with the same distance from the edge.
PALPAL BULB. With piriformis tegulum. Presence of retrolateral tegular apophysis, long prolateral superior keel, short prolateral inferior keel below and presence of a ventral retrolateral keel with small retrolateral striae below. Paraembolic apophysis below embolus, pointing forward, short and thin with conic shape (Figs 51–55). Cymbium with two asymmetric lobes, retrolateral larger and wider; prolateral lobe elongated and laterally flattened; retrolateral lobe without a distal retrolateral protrusion. Palpal tibia swollen, without mid-length concavity, with one prolateral row of 10 short spines, not aligned, disposed on apical third (Figs 56–57).
LEGS AND PALPS. Tibial spur I: prolatero-ventral spur with two separated branches of different length; retrolateral branch larger, flat at base, slightly procurved, with a small spine inserted subapically. Prolateral branch shorter slightly recurved, with contiguous spine with almost the same size (Fig. 58). Metatarsus I bent retrolaterally to tibial spur. Superior tarsal claws without teeth. Tarsal scopulae: I and II entire without longitudinal band of conical setae, III and IV divided by longitudinal band of conical setae. Metatarsal scopulae not dense, extension: I on distal third, II on more than distal half, III on distal half, IV on less than half. Clavate tarsal trichobothria in two rows, each with ca 12 trichae, interspersed with filiform trichobothria of different lengths. Tarsus IV cracked. Leg formula 4123 (Table 4).
SPINATION (proximal to distal). Cymbium and tarsi without spines. Palp: femur 0; patella 0; tibia p (1), (r) 10 megaspines. Leg I: femur (p) 2; patella (v) 1; tibia p (2), (r) 1-1-1; metatarsus (v) 0-1-1. Leg II: femur (p) 1; patela (v)1; tibia (v) 2-1-ap3, (p) 1; metatarsus (v) 1-2-ap2. Leg III: femur (p) 0-1-2, (r) 1; patela (r) 1; tibia (v)3-2-ap3, (p) 2, (r) 1; metatarsus (v)2-2-ap3, (p) 0-1-1, (r) 1-1-1. Leg IV: femur (p)1; patela (p)1; tibia (v) 3-2-ap2, (p)1-0-1, (r) 1-0-1; metatarsus: (v)2-3-ap3, (p) 0-1-1, (r) 1-1-1.
