Fig. 20. Rhipicephalus appefidiculatus, Neumann, 1901, nymphs : (a) normally 

 developed unfed specimen, dorsal and ventral aspects, spiracle and tarsus iv. ; (6) capitulum 

 and scutum of nymph which emerged from a larva removed from the host before it had 

 fed to repletion. Such smaU nymphs occur in nature. (Nuttall, 1913.)

(2) R. capensis, Koch, 1844. The scutum shows many punctations, and this, 

 combined with rugosities covering its surface, give it a dull appearance. 

 The adanal shields are rounded behind. The species is uncommon. The 

 determination is difficult. For biology see p. 344.
