von Martens infers that the loc. Zanzibar, originally quoted for 

 zanzibarica by Clessin, is incorrect, and that the species is the 

 same as that which was subsequently described by Morelet as 

 cornea. It is nearly allied to contorta. 



I. zanzibarica has recently been recorded by Thiele from Central 

 Africa.
