Nearctodesmidae is a family of flat-backed millipedes in the order Polydesmida. [1] [2] [3] [4] [5] These millipedes are found in northwestern North America. [4] This family includes the species Nearctodesmus salix . The defensive secretion of this millipede consist of hydrogen cyanide, benzaldehyde, 3-methylbutanoic acid, and 2-methylbutanoic. This evidence confirms that cyanogenesis extends to the family Nearctodesmidae. [6]
Authorities often consider Nearctodesmidae to be a junior synonym of Macrosternodesmidae. [7] [8] [9] Many of these authorities demote Nearctodesmidae and place the genera previously assigned to that family in a subfamily (Nearctodesminae) in the family Macrosternodesmidae. [7] [10] [11] Other authorities consider both Nearctodesmidae and Macrosternodesmidae to be junior synonyms of Trichopolydesmidae. [9] [12]
Authorities include at least the following genera in this family: [1] [3] [4]
