REVISIONARY CLASSIFICATION OF RUTILIINI 61 
apical part (Text-fig. 76). These differences appear to be constant, and to define 
two semi-sibling species, which cannot be differentiated on their external charac- 
teristics. The original type-material of imperialis is lost and a neotype herein 
designated fixes the name to the species with the genital form shown in Text-fig. 75. 
The existence of species which can only reliably be separated by male genitalia 
makes the determination of females rather hazardous, and it is not always possible 
to make completely dependable associations of males with females. As some of the 
primary types of described species are males and others females it is possible that 
more of the names are synonyms than are given in the list of included species which 
follows. Furthermore it is not yet clear whether pleural hair colour can be sexually 
dimorphic in any species, or whether hair colour can be variously black or yellow 
in the same sex in any species. At present black-haired and yellow-haired forms are 
assumed to appertain to different species, but this assumption may not be substan- 
' tiated in future when better criteria can be found for determining what is a species 
than we have at present (at least it appears, so far, that a distinctive form of male 
genitalia is correlated with a particular hair colour).
