5. clathrata has been regarded as a widespread African species (Gaede, 1929 : 496), 

 but it consists of at least three subspecies, one sufficiently different on genitalia 

 characters that it could perhaps be considered a distinct species. However, the 

 external morphology is similar in all three subspecies and two of them are known 

 only from single localities at the edge of the range of the nominate one. 



The nominate subspecies is widespread throughout West and Central Africa. It 

 appears to be restricted to the tropical rain-forest, whereas of the two subspecies, the 

 Kenyan one is from a drier zone. This is the most distinct of the subspecies both in 

 size and genitalia. The other species from Tanzania (Amani), differs in size and 

 colouration from the nominate one. This species is closely allied to Striglina 

 minutula (Saalmiiller) from Madagascar, differing only in small details in the 

 genitalia. It might be better to consider the Madagascan species as a subspecies of 

 clathrata but more information on the biology is needed.
