Mesobiotus radiatus ( Pilato, Binda & Catanzaro, 1991)

( Tables 2 and 3, Figures 1–10 )

Figures

Figure 1. Mesobiotus radiatus (Pilato, Binda & Catanzaro, 1991) from Kenya – habitus and cuticle morphology: A) dorsoventral projection of the entire animal (Hoyer’s me- dium, PCM); B) microgranulation on the dorsal cuticle seen in SEM. Scale bars in µm.

Figure 2. Mesobiotus radiatus (Pilato, Binda & Catanzaro, 1991) from Kenya – cuticular structures on legs: A, B) granulation on leg III seen in PCM and SEM, respectively; C, D) a pulvinus-like cuticular bulge on the internal surface of leg III seen in PCM and SEM, respectively; E, F) granulation on leg IV seen in PCM and SEM, respectively.Filled arrowheads indicate the cuticular bulge whereas empty arrowheads indicate faint muscle attachments under the claws. Scale bars in µm.

Figure 3. Mesobiotus radiatus (Pilato, Binda & Catanzaro, 1991) from Kenya – buccal apparatus and the oral cavity armature: A) dorsoventral projection of the entire buccal apparatus (PCM); B, C) oral cavity armature with all three bands of teeth visible, dorsal and ventral view respectively (PCM); D, E) placoid morphology seen in PCM and SEM, respectively. Scale bars in µm.

Figure 4. Mesobiotus radiatus (Pilato, Binda & Catanzaro, 1991) from Kenya – the oral cavity armature of two specimens seen in SEM: A) dorsal and ventral side; B) magnification on dorsal side. Filled indented arrowheads indicate teeth of the first band, empty indented arrowheads indicate teeth of the second band, the ridges of the third band are marked with “M” (dorsomedian tooth), “L” (lateral teeth, both dorsal and ventral), and “m –m ” (ventromedian teeth). Scale bars in µm.

Figure 5. Mesobiotus radiatus (Pilato, Binda & Catanzaro, 1991) from Kenya – claws: A, B) claws I and IV seen in PCM, with smooth and dentate lunulae, respectively; C, D) claws II and IV seen in SEM, with smooth and dentate lunulae, respectively; E) the overall view of the hind legs, note better developed teeth on lunulae under posterior claws and granulation morphology; arrowheads indicate spurs at the claw bases. Figures A and B assembled from several photos. Scale bars in µm.

Figure 6. Mesobiotus radiatus (Pilato, Binda & Catanzaro, 1991) from Kenya – egg seen in PCM: A, B) midsection under 400× magnification; C, D) surface under 400× magnification; E, F) surfaces under 1000× magnification. Photos of each column show the details of a single egg. Arrowheads indicate pores on the egg surface between processes. Scale bars in µm.

Figure 7. Mesobiotus radiatus (Pilato, Binda & Catanzaro, 1991) from Kenya – egg processes seen in PCM under 1000× magnification. Photos of several eggs. Arrowheads indicate pores in the apical process wall. Scale bars in µm.

Figure 8. Mesobiotus radiatus (Pilato, Binda & Catanzaro, 1991) from Kenya – entire eggs seen in SEM. Scale bars in µm.

Figure 9. Mesobiotus radiatus (Pilato, Binda & Catanzaro, 1991) from Kenya – details of eggs seen in SEM: A, B) – egg surface between processes; C–F) egg processes morphology. Scale bars in µm.

Figure 10. Mesobiotus radiatus (Pilato, Binda & Catanzaro, 1991) from Kenya – details of eggs seen in SEM: A–E) porous apices of egg processes with short flexible filaments; F) magnification of flexible filament. Scale bars in µm.
