118 Rowland M. Shelley 



Union County, Illinois. Causey (1954^) erected Tubaphe for T. levii, 

 from the Olympic rain forest, Jefferson County, Washington, and 

 (Causey 19546) recorded M. elrodi from Evans, Stevens County, Washing- 

 ton. Johnson (1954) included S. placidus among his list of Michigan 

 millipeds but gave no specific localities. Chamberlin and Hoffman 

 (1958) listed all species recognized at that time, added New York and 

 Virginia to the range oiS. placidus, placed L. borealis and S. michigana 

 in synonymy, and transferred S. tertius into the chelodesmid genus 

 Aphelidesmus, where it clearly belongs. Its purported occurrence in 

 Texas can only reflect a labelling error, as the genus otherwise occurs 

 from Costa Rica southward (Hoffman 1979). 



Little has appeared on the Chonaphini in recent years. Hoffman 

 (1969) noted that Semionellus is monotypic, related to Chonaphe and 

 Montaphe, and cited its range as being from Minnesota to Illinois and 

 Ohio, with isolated populations in western Maryland, the adjacent 

 part of West Virginia, and the Virginia Blue Ridge. Buckett and Gardner 

 (1969) erected Metaxycheir for M. prolata, occurring near Moscow, 

 Latah County, Idaho, which they erroneously recorded as Nez Perce 

 County. They correctly related Metaxycheir to Chonaphe, but apparent- 

 ly unaware of Verhoeff's subfamily, placed these genera, along with 

 Harpaphe Cook and Hybaphe Cook, in the Orophinae, erected by 

 Hoffman (1964) to accommodate Orophe Chamberlin and Pamelaphe 

 Hoffman. This heterogeneous taxon was disassembled by Hoffman 

 (1979), who transferred Harpaphe and Hybaphe to the new tribe Harpa- 

 phini and reduced the Chonaphinae and Orophinae to tribal status. 

 Loomis and Schmitt (1971) described the final nominal species, C. 

 serratus, from Sanders and Lake counties, Montana, alluded to the 

 occurrence of C. armata along Puget Sound, Washington, where the 

 only congener is C. remissa, and reported numerous new records of 

 M. elrodi from Lake, Missoula, and Sanders counties, Montana, and 

 Idaho County, Idaho. 



The final relevant works concern Canada. Kevan (1983) listed 

 all the taxa as potential Canadian inhabitants, and Shelley (1990) 

 described Metaxycheir pacifica from Vancouver Island and summa- 

 rized the distribution of the tribe and its generic and specific composi- 

 tion, omitting Tubaphe and T. levii. Shelley (1993a) synonymized 

 M. pacifica under T. levii after recollecting the latter in the Olympic 

 Mountains. 



Thus, at this writing, five genera and nine species comprise the 

 Chonaphini. They are listed chronologically below along with type 

 localities and other reported occurrences.
