LITERATURE REVIEW 



The subfamily Chonaphinae was proposed by Verhoeff (1941) 

 for Chonaphe, which was erected by Cook (1904) for Polydesmus 

 armatus. This species was one of four myriapods that Harger (1872) 

 described from an unspecified site along the John Day River, Oregon, 

 which I (Shelley 1993/?) inferred was near Canyon City, Grant County, 

 on the western slope of the Blue Mountains. The third xystodesmid to 

 be named from western North America, after P. {Leptodesmus) hay- 

 denianus Wood (1864), now in Harpaphe, and P. dissectus Wood 

 (1867), now in Motyxia, C. armata is also the second oldest chonaphine 

 species behind P. (L.) placidus, described by Wood (1864) from an 

 unspecified site in Michigan. Immediately following the latter's description. 

 Wood (1864) proposed the synonym, "P. (L.) floridus var.?," and 

 Wood (1865) repeated the accounts of both species, providing a gonopod 

 illustration of the former. 



Sixteen years after Harger's work, Bollman (1888) recorded 

 L. placidus from Boswell, Benton County, Indiana. In a listing of 

 North American myriapods, Bollman (1893) included L. armatus and
