REMARKS 



Koch (18/W.) based his original description on females only. 

 His material was reported as from Senegal and Egypt. It is most 

 likely that the Egyptian record is due to a mistaken locality 

 label. Just how the Senegal specimen has been associated vrith 

 what is today called R. simus senegalensis has not been deter- 

 mined. A female specimen of the R. simus group from Koch's time 

 would be difficvilt to identify vaTh any degree of certainty, 

 especially to subspecies. Neumann (1911) synonymized senegalensis 

 under R. simus . Zumpt (1%3A,1950A) described what is now con- 

 sidere'd as R. simus senegalensis . 



A number of the Sudan and Tanganyika collections listed here- 

 in were sent to Santos Dias for identification, along with some 

 specimens of R. longus . The R. simus senegalensis material was 

 determined by^him as R. longvis and the R. longus material was 

 labelled R. capensis pseudo longus . 



Zumpt (19/i-3A,1950A) warns his readers that heavily punctate 

 R. simus senegalensis may superficially resemble R. longus . The 

 R. longus of Santos Dias (1953D) appears to be what Zumpt cc 

 "siders a heavily punctate R. simus senegalensis .

A further note is necessary concerning collections listed 

 above as simus- senegalensis intergrades from elephants near Kenisa, 

 Bahr El Ghazal Province. These are comparatively small, brownish 

 specimens, with simus scutal punctation, posteromedian and para- 

 median grooves absent or very faintly indicated, and adanal shields 

 showing every degree of variation from the most typical simus type 

 to the most typical senegalensis type. These series nicely corro- 

 borate Zumpt 's treatment of senegalensis as a subspecies of simus . 



IDENTIFICATION 



Male ; Within the R. simus group, as described in the key and 

 Tinder R. simus , males oT the subspecies senegsilensis are referred 

 to a group vn.th sickleshaped adanal shields. The scutal outline 

 is definitely id.der in relation to length than in most specimens 

 of R. s. simus and the scutal storface is flat, not arched as in
