*" '''^'e suggest this name, emphasizing the distinctive character of the light and dark 

 hands (equal in length), for the species described in detail by Stickel (loc. cit.). A name 

 is required since we believe all clearly valid species should be made known with a name to 

 Kystematists. If the available material of a species unknown in the literature does not 

 merit proposal of a name for it, then it likewise does not warrant proposal as a species 

 into zoological literature. This general policy does not, of course, apply to material of 

 dubious specific allocation.
