Figures 1–7 , 102 , 105A ; map 1

Zyngoonops clandestinus Benoit, 1977: 246 , figs. 6– 10 (female holotype from Visiki , Kivu, D.R.C., in MRAC; examined).

DIAGNOSIS: Females resemble those of Z. moffetti in having only two eyes (figs. 1C, 3B) and short dorsal and postepigastric scuta (fig. 102D, E) but differ in having a more elongated epigastric scape (figs. 1F, 7B, 105A).

MALE: Unknown.

FEMALE (figs. 1–7, 102, 105A): TL 1.52. Carapace length 0.59, width 0.45. Abdomen length 0.93, width 0.54. Habitus as in figure 102. Carapace microsculpture very shallow. Two small, round to oval eyes, approximately one diameter apart (fig. 3B). Prongs as in figure 3C–F. Abdomen elongated ovoid. Booklung covers medium sized. Ventral lip constricted in the middle (fig. 5D). DS small, ovoid, covering only 1/4 of abdomen length (fig. 102D). PES short, leaving more than half of ventral abdomen uncovered (fig. 102E). Lateral apodemes of medium length. Epigastric scape narrowed at tip (figs. 1F, 7B, 105A). Internal genitalia as in

figure 7E, F. Genital pouch present (fig. 7E). Distal part of genital duct highly coiled (fig. 7E).

MATERIAL EXAMINED: D. R.C.: Kivu, Visiki forest, 00 ° 219N, 029 ° 099E, Dec. 22, 1971, Lejeune M. (PBI_OON 2191, MRAC 140.846), 1 female (holotype). Same data (PBI_OON 28773, MRAC 224.107), 1 female.

DISTRIBUTION: Known only from the type locality in the Kivu region, D.R.C. (map 1).
