Figures 31–36 , 103 ; map 5

TYPES: Female holotype: D.R.C., Masako Forest, 00 ° 359N, 025 ° 119E, Dec. 14, 2007, primary forest, Jocqué R. and Juakaly J.-L. (PBI_OON 29108, MRAC 222.493). Paratype: same data (PBI_OON 29085, MRAC 222.494), 1 male.

ETYMOLOGY: Named after the Flemish humanist Nicolaes Rockox (1560–1640). Rockox was a numismatist and archaeologist, as well as an important art collector and patron.

DIAGNOSIS: Males can easily be recognized by the extremely long, whiplike median projections (figs. 31A–C, E, F, 103A–C), females by the very long epigastric scape that reaches the posterior margin of the PES (figs. 36C, D, 103F).

MALE (figs. 31–35, 103A–D): TL 1.04. Habitus as in figures 31A, 34C. Carapace: stripes as in Z. beatriceae , but dorsal stripe shorter; setae on dorsal midline directed posteriorly. Clypeus with many posteriorly directed setae (fig. 31F). Six eyes; ALE approximately one diameter apart; PME oval, almost touching; PLE well separated from PME; posterior eye row strongly procurved. Endites with a median projection (mp), a P2 projection, and one additional projection (Px); mp directed anteriorly, extremely long, passing between the chelic- erae (fig. 31A, E), then looping upward and backward (fig. 31A, E, F) to end near posterodorsal tip of carapace (fig. 31A, C); P2 situated anterior to seta s4, rather elongated, with anterior edge flattened into narrow flange (figs. 32D, E, 33A, B); Px situated anterior to P2, crestlike (fig. 33B– D). Booklung covers medium sized. Ventral lip not constricted (fig. 35A). DS long, covering almost entire dorsum, fused to ES (fig. 34C, D). PES fused to ES, forming single ventral scutum that covers nearly full length of abdomen (fig. 34E). Lateral apodemes very long (fig. 103D). PLS with three spigots.

FEMALE (figs. 36, 103E, F): TL 1.22. Habitus as in figure 36A, B. Carapace: on each lateral surface a short stripe at level of coxal insertion III (fig. 36A); most setae on dorsal midline directed anteriorly. Most clypeus setae directed anteriorly. Eyes as in male. Booklung covers relatively small. DS long, covering almost entire dorsum (fig. 103E). PES long, most of ventral abdomen covered (fig. 103F). Epigastric scape very

long, reaching posterior margin of PES (figs. 36C, D, 103F).

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Known only from the type locality in the Orientale province, D.R.C. (map 5).
