FIGURE 20. A–I Nanohystrix hammerae n. sp. juveniles, stereo- (A–C) and compound (D–I) light microscope images. A, larva with all legs in walking position, lateral aspect; B, larva, anterior half in dorsal aspect, with right legs I, II; C, deutonymph with legs I and II laterally directed, dorsal aspect; D, tritonymph, left anterolateral region of hysterosoma showing muscles, cf. Fig. 8A; E, tritonymph, lateral aspect (filled with food boluses and gregarine parasites, see Fig. 22G),with insert showing enlargement of prodorsal strut; F, tritonymph, seta e1 and cuticular disk cd4, dorsolateral aspect, anterior to left; G, protonymph, distal part of tarsus III, lateral aspect; H, tritonymph, distal part of tarsus III, dorsal aspect; I, protonymph, left leg IV, abaxial aspect (seta ft" torn away). Abbreviations: cd4 (cuticular disk), e1.mu (depressor muscles of seta e1); pr.mu (prodorsal retractor muscles), str (prodorsal strut); other labels indicate setae (see text). D–I composites of 5–20 layers. Scale bars: 100 Μm (A B, E); 25 Μm (D, F–I). Scale not determined for C, probably similar to A.
