This species is known only from the male type in the British Museum 

 and a male specimen in the U.S. National Museum, both from the 

 same locahty. The shape of the aedeagus and the large posterior 

 process from its middle, plus the shape of the anellar lobes, provide 

 ample distinguishing characters in the male genitalia.
