RMpicephalus 
yellow integument, extends far beyond the scutum posteriorly in 
distended specimens, the caudal appendage being unusually strong, but 
without a terminal plaque. Red-brown plaques correspond to the 
festoons on either side. Only one of the 37 (/s was without the caudal 
appendage, and in this the accessory plates were hardly visible.

Original, C. W. 
Ventral aspect : Integument yellowish-white in all the specimens. 
Auricular ridges slight. Goxa I rather short; coxa II triangular; 
the internal spur almost absent on coxae II and III ; the spurs on 
coxa IV small and well separated. Anal plates somewhat clavate, usually 
with an internally directed point (as in R. capensis); they tend to become 
broader distally in large specimens. Accessory plates long superficial 
strips of hard chitin, salient posteriorly. Legs rather long; pads long. 
Spiracles enlarged anteriorly, then constricted to a long slightly curved 
tail of uniform width. 
Female. Capitulum remarkably long (O'S mm.), due chiefly to the 
unusual length of articles 2 and 3 of the palps; basis capituli 
punctate, with straight posterior border and slight cornua; porose areas 
large, the interval rather greater than the diameter. Palps with article 
1 long, but partly concealed by article 2 which is very long and 
produced backward to a point; article 3 long and narrowing distally. 
Scutum sub-circular, deeply emarginate, deeply punctate all over;
