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,
