sternal process and is C. monstrosa of present usage; the smaller 
specimen lacks the process and is C. buckelli of Hebard. It is the C. 
buckelli specimen which bears a red ‘Type 792’ label. Uhler’s 
description concentrates on the larger specimen. Thus monstrosa is 
said to have a “pointed keel-like elevation, projected backwards 
upon the segment, grooved and emarginated at tip”, i.e. a sternal 
process. He does not indicate that such a structure is absent from 
the other specimen. 
Caudell (1904) described a variety of C. monstrosa which he 
called Cyphoderris monstrosa piperi. His types, which we have seen, 
are a male and a female from Mt. Rainier, Washington, housed in 
the U.S. National Museum. The male has a sternal process identical 
with that of Uhler’s larger specimen and the female has Ander’s 
organs (see below). 
In 1922 Fulton collected a series of males in Oregon about 30 mi. 
southwest of Crater Lake (Fulton, 1930). He compared these with 
specimens furnished him by E. R. Buckell from southern British 
Columbia and found that Buckell’s specimens lacked a genitalic 
process. Drawings were sent to Nathan Banks and to Caudell who 
compared them with the types of monstrosa and piperi. 
It might now have become apparent that Uhler’s types differed in 
their genitalia and that only the larger was of the same species as 
piperi. Since the published description applied substantially to the 
larger specimen one would then have expected it to be designated as 
monstrosa. But for some reason piperi was given specific status by 
Fulton and applied to the taxon with the sternal process while 
Uhler’s name was conferred upon the smaller of Uhler’s two species. 
Probably it was at this point that the red type label was appended at 
Harvard. 
Hebard (1934), responding to Uhler’s published description, 
recognized piperi as a synonym of monstrosa and gave the name 
buckelli to the species without the sternal process. It is clear that he 
did not examine Uhler’s types and was unaware that one of these 
was his new species. Uhler did not designate a holotype and so in 
accordance with Article 74 of the code and in the interest of 
taxonomic stability, we here designate as lectotype the larger of the 
two specimens in his type series, that possessing the sternal process. 
This ensures that application of the name monstrosa continues in 
conformity with present custom.
