(PBI_OON 28637, MRAC 224.194). Paratype : same data (PBI_OON 28550, MRAC 224.192), 1 female . Paratype : same data (PBI_OON 33274, MRAC 230.591), 1 male . ETYMOLOGY: Named after the Scottish writer and publisher Robert Chambers (1802–1871). In his book Vestiges of the Natural History of Creation (1844) Chambers argued for an evolutionary view of life. DIAGNOSIS: Males resemble those of Z. beatriceae but differ in having a P2 projection with a prominent anterolateral extension (figs. 46E, F, 47C, 48A, B). Females can be recognized by the large scape that gradually widens posteriorly (figs. 49D, 52E, 105D). MALE (figs. 45–48, 49A, B, 104A–F): TL 1.45. Habitus as in figure 45A. Carapace strongly elevated in lateral view; posterodorsal part reclining (fig. 45B). Carapace stripes as in Z. beatriceae . Inner surface of carapace wall showing ridges; the ridges presumably correspond to the red stripes (fig. 45C). Six eyes; ALE about one diameter apart; PME oval, touching or almost touching; PLE oval, well separated from PME. Endites as in Z. beatriceae , but P2 with a prominent anterolateral extension (figs. 46E, F, 47C, 48A, B). Booklung covers medium sized, darker than surrounding scutum. Ventral lip not constricted. DS long, covering almost entire dorsum, fused to ES (fig. 48F). PES fused to ES, forming single ventral scutum that covers nearly full length of abdomen. Lateral apodemes long, distally slightly inward curved. PLS with three spigots (fig. 49B). Fig. 23. Zyngoonops redii , new species , female. A. ES and PES, dorsal view. B. Internal genitalia, dorsal view, showing straight (sd) and coiled (cd) part of duct. C. Detail of B, showing straight part of duct. D. Detail of B, showing proximal part of duct. E. Other specimen, internal genitalia, dorsal view. Scale bars: 2 Mm (C, D), 5 Mm (B, E), 30 Mm (A). FEMALE (figs. 49C, D, 50–56, 104G, H, 105D): TL 1.53. Habitus as in figure 50A. Carapace without stripes. Eyes as in male. Booklung covers medium sized, darker than surrounding scutum. Ventral lip not constricted (fig. 51F). DS long, covering almost entire dorsum. PES long, most of ventral abdomen covered (fig. 51E). Epigastric scape as in figures 49D, 52E, 105D, more than half as long as PES. Internal genitalia as in figures 52F, G, 53–56. Genital pouch present (figs. 52G, 53E). Distal part of genital duct highly coiled (fig. 53A, F); a section through the coiled part reveals numerous small, round structures (fig. 54B); these structures have a thick wall and a dark center (presumably they are cross sections through the duct).
