A small species belonging to the squamidatus group of Dietz, 

 in which it may best follow persimilis, though not agreeing closely 

 with any species of the group. The small size and lack of true 

 scales on the upper surface distinguishes it from all but albopilosidus, 

 which differs in its erect, coarser vestiture among other charac- 

 ters.
