TYPES: Female holotype: D.R.C., Ruwenzori, Kyandolire, lieu dit camp des gardes, 00 ° 209N, 029 ° 459E, Oct. 23, 1952, elev. 1700 m, Vanschuytbroeck P. and Kekenbosch J. (PBI_OON 28547, MRAC 224.240). Paratypes: same locality, Oct. 18, 1952, elev. 1700 m, same collectors (PBI_OON 33811, 33812, MRAC 230.506, 230.507), 1 male, 1 female. Paratype: same locality, Oct. 8, 1952, terreau, berlese, elev. 1700 m, same collectors (PBI_OON 28642, MRAC 224.234), 1 male.

ETYMOLOGY: Named after the Dutch naturalist Jan Swammerdam (1637–1680). Swammerdam made key discoveries in human physiology and pioneered the scientific study of insects.

DIAGNOSIS: Males resemble those of Z. marki but have slightly shorter median projections (fig. 57D, E) and smaller P2 and P3 projections (figs. 57D–F, 58B). Females resemble those of Z. redii but lack a groove in the epigastric scape (figs. 60B, 61D–F).

MALE (figs. 57–59): TL 1.12. Habitus as in figure 57A. Carapace without stripes. Six eyes; ALE less than one diameter apart; PME oval, touching or almost touching; PLE round to oval, well separated from PME. Endites with four projections (mp, P2, P3, P4); mp rather short, somewhat thornlike, directed anteriorly (figs. 57D, E, 58D); P2 relatively small, broad, somewhat platelike, median surface strongly ribbed, shaft of seta s4 resting on surface of projection (figs. 57D– F, 58B, E, F); P3 cone shaped, relatively small (figs. 57E, 58B, F); P4 somewhat cone shaped (figs. 58E, F, 59B). Setae s1–3 as in figures 57D, E, 58B. Booklung covers relatively small. Ventral lip not constricted. DS long, covering almost entire dorsum, fused to ES (fig. 57A). PES fused to ES, forming single ventral scutum that covers nearly full length of abdomen. PLS with two spigots.

FEMALE (figs. 60–64): TL 1.15. Habitus as in figure 60A. Carapace without stripes. Eyes as in male. Booklung covers relatively small. Ventral lip not constricted. DS long, covering almost entire dorsum. PES long, most of ventral abdomen covered (fig. 61C). Epigastric scape triangular, elevated above PES (figs. 60B, 61D– F). Internal genitalia as in figures 62–64. Genital

pouch present (fig. 62B). Distal part of genital duct highly coiled (figs. 62D, 63D, E, 64A).
