description: Zambedania madagascariana sp. n.
Figs 7–13.
Diagnosis. The female of Z. madagascariana is unique among those of its congeners by having prodorsal stigmata subdivided. It differs from Z. argentiniana by stigmata being short, about ca. 1/3 of PdS length and located posteriorly, aggenital plate smooth, tibiotarsus I robust, tarsal IV empodium present, and from Z. africana by Ta IV with one claw.
Description. Phoretic female (holotype; measurements in Table 2).
Gnathosoma (Fig. 8 A, not to scale). Cheliceral setae ch1 ~ ch2 horizontally aligned slender, barbed. Both palpal setae d Fe and d Ge smooth. Supracoxal setae pp not evident. Dorsomedian apodeme clearly visible. Ventral structures not seen. Pharyngeal pumps present; however, shapes not clearly seen: first pump in gnathosoma, second under PdS, third in opisthosoma (Fig. 8 B, not to scale).
Idiosomal dorsum (Fig. 7 B). PdS with anterior edge apparently rounded. Stigmatal slits not reaching anterior edge (Fig. 8 B). Seta v2 relatively short, inserted anteriad of scapulars sc2. Bothridial sc1 elliptical globose, coarsely barbed; sc2 very long and strongly barbed. Opisthosomal dorsal setae barbed, not on protuberances. Setae h1 ~2 h2. On Ps pseudanal setae ps1 shortest. No cupules seen.
Idiosomal venter (Fig. 7 A). Both ap1 and ap2 complete. Appr posteriorly links continuously to well-developed apsej. Sclerotized ap 3 and 4 extend from anterior edges of bases of legs III and IV and fuse with appo. Ap5 rudimentary, at posterior edge of base of legs IV. Ag distally undulated, subcircular; smooth. Ventral setae smooth to slightly or strongly barbed. Seta 4b longest. On Ps seta ps3 longest.
Legs. Legs I (Figs. 9–10). TiTa: apical claw robust, sharp; flanked on each side by strongly sclerotized leafshaped unguinals u' - u". Eupathidia: proral (p") laterad of claw, tectals (tc', tc") on common pinnaculum; fastigials (ft'- ft") inserted dorso-laterad of tectals, on separate pinnacula. Relative sizes of eupathidia: ft' <ft" (longest of all); tc' <tc"; p"> tc' but <ft'. Solenidia: ω long and slender, φ1 and, φ2 slightly <½ ω. Relative sizes of setae: pl' <pl", both one-sidedly barbed; one-sidedly barbed pv' <barbed pv"; weakly barbed s of intermediate length. Tibial v'> v", both feathered; barbed l' ~ one-sidedly barbed l"; one-sidedly barbed d longest on segment, placed closely to cluster φ1- φ2; barbed seta k ~ l'. Ge: v'> v", both barbed; l" ~ ½ l'. Fe: d> 3 1/ 4 v "; barbed v" <one-sidedly barbed l'. Tr: v' slightly over ~ 5/6 Ge v'.
Legs II (Fig. 11). Padlike empodium between two simple, curved claws. All leg setae barbed Ta: tc'> pl" and tc"; pv'> pv"; u' distalmost and shortest seta on segment; baculate solenidion ω ~ 2 Ti φ. Ti: v"> v', both onesidedly barbed; φ ca. ~ 1/3 of length of segment and close to d. Ge: v' ~ l' and l". Fe: d longest seta of leg II, reaching to base of pretarsus; v" <one-sidedly barbed l'. Tr: v' as long as Fe v".
Legs III (Fig. 12). Two terminal claws and empodium as in leg II. All setae barbed. Ta: pl" longest seta on segment; tc' stout, ~ slim tc"; pv' ~ pv"; u' short, distalmost on segment. Ti: d short, close to elongate φ; v' longest tibial seta; v" ~ l'. Ge: one-sidedly barbed l'> v'. Fe: d longest on leg; seta v' missing on left leg, present on right leg (Fig. 12 B), somewhat <d. Tr: v' one-sidedly barbed ~ 3/4 Fe d.
Legs IV (Fig. 13). Only one laterally-placed claw on leg IV, next to empodium. All leg setae barbed. Ta: pl" longest seta on segment; tc'′> tc'; pv'> pv". Ti: solenidion φ small; l' ~ v'; v' ~ v"; seta d longest tibial seta. Ge: v' <Ti l'; Fe: d longest on leg IV but shorter than whole leg, v' ~ 1/3 d; Tr: v'> Fe v'.
