Males ; The red tick is usixally large (5 mm, long) though 

 smaller specimens do occur. Its dark scutum contrasts greatly 

 with the reddish body integument and saffron legs. The dark 

 eyes are hemispherical, protriiding, smd orbited, similar to those 

 of hyalommids but to no other rhipicephalids except R. oculatus 

 (and, partially, to R. pravus ). Scutal punctations are of mediim 

 and large size and so numerous as to cause the scutxim to appear 

 shagreened. Lateral grooves, a posteromedian groove, and para- 

 median grooves are pronounced. A large, pointed process from 

 coxa I is visible dorsal ly. The hx:ige adanal shields, very wide 

 and posteriorly semicircular in outline, are also unique. 



Female: This sex is colored as in the male and has similar 

 scutal punctations and eyes so that it can never be mistaJcen. 

 The scut\m lacks lateral grooves. 



The larva and nymph have been described and illustrated by 

 Theiler (19^). "^ 



Note ; The subspecies R. evert si mimeticus Donitz, 1910(b), 

 has yellow-ringed legs whil'e those of the typical evert si are 

 unicolorous.
