There are no pattern or genitalia differences between plagosana 

 and unguicella. At most they could be but racially distinguished and 

 I do not believe even such a splitting would be valid. There seems 

 to be a little more intensity in the black dusting in American speci- 

 mens, but they are somewhat variable and the character is not con- 

 stant.
