SUBFAMILY RHINIINAE 
Members of the Rhiniinae lack intrapostocular cilia, have very 
narrow occipital orbits, and most of the species have the epistoma 
protuberant. Since only one species is known to occur in the 
Western Hemisphere, no attempt has been made to give a 
synopsis of the characters for the subfamily, for those noted in 
the key will apparently suffice.
