Kery TO SPECIES OF THE SUBGENUS DONOVANIUS 
[Note : The limits of species in this subgenus are very difficult to determine. There are few 
structural characters that appear to have much value in separating species, and the § genitalia 
are so uniform (or at least differ in such a subtle and intangible way) that they have little value 
for species recognition. It is often difficult reliably to associate males and females, and there 
is clearly much variation within a species in such features as hairiness of parafacials, develop- 
_ment of median marginal setae on T3, and the number of proclinate orbital setae in females. 
At present the entities considered to be species differ mainly in their general appearance as 
shown by body colour, hair colour and size; these features seem to separate specimens into 
fairly convincing species, but there is considerable intergradation (new synonymies established 
_ above are based on absolute agreement between types). The key here given must be treated 
| as very tentative: it is by no means certain that the named taxa represent distinct species, 
and museum collections may contain undetermined specimens that will not conform with the 
key. R. spinolae is omitted as the type has not been located and the name remains enigmatic. ]
