Figures 17–23 , 105C ; map 3

TYPES: Female holotype: D.R.C., Kivu, plaine de la Ruindi, Bulemba, 00 ° 389S, 029 ° 229E, June 15, 1972, dans termitière, Lejeune M. (PBI_OON 33276, MRAC 230.583). Paratype: same data (PBI_OON 33277, MRAC 230.582), 1 male.

ETYMOLOGY: Named after the Italian scientist Francesco Redi (1626–1697). Redi was one of the first to cast doubt on the theory of spontaneous generation.

DIAGNOSIS: Males can be recognized by the very short median projection (figs. 19C, F, 20A, C–G). Females can be recognized by the short epigastric scape with a shallow groove (figs. 17D, 22B, C, 105C).

MALE (figs. 17B, 18–20): TL 1.28. Habitus as in figure 17B. Posterior half of carapace with three red stripes, one on dorsal surface and one on each lateral surface; the three stripes joining on the posterior surface of the carapace; each lateral stripe has a very short, downward-projecting sidebranch at the level of coxal insertion III. Six eyes; ALE less than one diameter apart; PME oval, touching or almost touching; PLE well separated from PME; posterior eye row more or less procurved in dorsal view. Prongs as in figure 18C, D, well developed. Endites with a median projection (mp) and a P1 projection; mp very short (figs. 19C, F, 20A, C–G); ventral surface of P1 slightly vaulted (figs. 19F, 20F, G). Booklung covers relatively small. Ventral lip not constricted. DS long, covering almost entire dorsum, fused to ES. PES fused to ES, forming single ventral scutum that covers nearly full length of abdomen (fig. 17B). Lateral apodemes very long, distally inward curved. PLS with two spigots.

FEMALE (figs. 17A, C, D, 21–23, 105C): TL 1.24. Habitus as in figure 17A. Carapace without stripes. Eyes as in male. Booklung covers relatively small. Ventral lip not constricted (fig. 21E). DS long, covering almost entire dorsum (fig. 17A). PES long, most of ventral abdomen covered (fig. 21D). Lateral apodemes very long. Epigastric scape short, triangular, with a shallow groove posteriorly (fig. 22B) that has a small round opening (fig. 22D). Internal genitalia as in

(circle) and Z. swammerdami (square).

figure 23. Genital pouch absent. Distal part of genital duct highly coiled (fig. 23B, E).

OTHER MATERIAL EXAMINED: D.R.C.: Kivu, plaine de la Ruindi, Bulemba, 00 ° 389S, 029 ° 229E, June 20, 1972, dans termitière, Lejeune M. (PBI_OON 28694, MRAC 144.465), 2 females.
