elev. 2700 m, Vanschuytbroeck P. (PBI_ OON 33275, MRAC 230.390). Paratype: same data (PBI_OON 28506, MRAC 224.225), 1 male.

ETYMOLOGY: Named after the author’s mother, Beatrice Coen.

DIAGNOSIS: Males resemble those of Z.

chambersi but the P2 projection lacks an anterolateral extension (figs. 38F, 39A–D). Females can be recognized by the large, posteriorly rounded epigastric scape (figs. 37F, 42E, 105E).

MALE (figs. 37A, C–E, 38–40, 41A, B): TL 1.59. Habitus as in figure 37A. Carapace strongly elevated in lateral view; posterodorsal part reclining (fig. 37A, C). Posterior half of carapace with three conspicuous 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, downwardprojecting sidebranch at the level of coxal insertion III; between each lateral stripe and dorsal stripe three much fainter, thinner stripes (upper, middle, and lower stripes; fig. 37C–E). Six eyes; ALE less than one diameter apart; PME oval, touching or almost touching; PLE round to oval, well separated from PME; posterior eye row straight or slightly procurved in dorsal view. Endites with five projections (mp, P2, P3, P4, P5); mp relatively long, directed anteriorly (fig. 39C); P2 large, relatively broad, somewhat platelike, shaft of seta 4 resting on surface of projection (figs. 38F, 39A, C–F, 40A); P3 cone shaped, relatively large (figs. 38F, 39B, D, F, 40A); P4 somewhat cone shaped, situated very close to P2 (fig. 39E, F); P5 crestlike, somewhat triangular (figs. 38F, 39D–F, 40A). Setae 1–3 long (fig. 39A). Booklung covers relatively small. Ventral lip not constricted (fig. 40C). DS long, covering almost entire dorsum, fused to ES (fig. 37A). PES fused to ES, forming single ventral scutum that covers nearly full length of abdomen (fig. 40B). PLS with three spigots.

FEMALE (figs. 37B, F, 41C–F, 42– 44, 105E, F): TL 1.45. Habitus as in figure 37B. Carapace without stripes. Eyes as in male. Booklung covers medium sized. Ventral lip not constricted (fig. 42D). DS long, covering almost entire dorsum (fig. 37B). PES long, most of ventral abdomen covered (fig. 42C). Epigastric scape about half as long as PES, posteriorly rounded (figs. 37F, 42E, 105E). Internal genitalia as in figures 43, 44. Genital pouch

present (figs. 43B, G, 44D, F). Distal part of genital duct highly coiled (figs. 43D, E, 44A, E).
