Original scientific description:

Ross, H. H. and Yamamoto, T. (1966). Two new sister species of the winter stonefly, genus Allocapnia (Plecoptera, Capniidae). Entomol. News (67?): 265-267.*

 

* The exact volume in which this species was described is somewhat of a mystery. I have examined five different references of the paper, of which four cite different volume no.'s: 27, 57, 67 and 77. How a single reference can be cited so differently in various publications is quite simply beyond me. Since "67" is quoted twice amongst the five instances of referring to this paper which I can find, I have chosen to go with this number, placing it in brackets with a question mark after the number to alert the reader to the fact that it is disputed.
