Figures 14–16 , 105H ; map 2

TYPE: Female holotype: Central African Republic, Prefecture Sangha-Mbaére´, Parc National Dzanga-Ndoki, Mabéa Bai, 21.4 km 53 ° NE Bayanga, 03 ° 029000N, 16 ° 249360E, May 1–7, 2001, rainforest, elev. 510 m, B.L. Fisher (PBI_OON 3481, CAS).

ETYMOLOGY: Named after the American palaeontologist Charles D. Walcott (1850– 1927). Walcott discovered the Burgess Shale quarry and described many of the fossils found there.

DIAGNOSIS: Females resemble those of Z. clandestinus and Z. moffetti but have six eyes and a pointed epigastric scape (figs. 14F, 105H). The sternal prongs are less pronounced than in other Zyngoonops species (fig. 15E).

MALE: Unknown.

FEMALE (figs. 14–16, 105H): TL 1.20. Habitus as in figure 14A, B. Carapace microsculpture very shallow. Six eyes, ALE less than one diameter apart, PME oval, touching or almost touching, PLE well separated from PME (fig. 15D). Prongs weakly developed (fig. 15E). Abdomen elongated ovoid. Booklung covers medium sized. Posterior surface of paturon could not be examined. DS small, covering only 1/3 of abdomen length (fig. 14C). PES short, leaving more than half of ventral abdomen uncovered (fig. 14D). Lateral apodemes rather short. Epigastric scape as in figures 14F and 105H, almost as long as PES.

OTHER MATERIAL EXAMINED: one female taken with the holotype (abdomen missing; carapace used for SEM) .

DISTRIBUTION: Known only from the type locality in Sangha-Mbaére´, Central African Republic (map 2).

NOTE: Z. walcotti is assigned to Zyngoonops with some hesitation. The sternal prongs are weakly developed compared to other Zyngoonops species (see fig. 15E). The genital anatomy and pedicel tube morphology of Z. walcotti could not be examined in detail.
