Xystocheir brachymacris is a species of flat-backed millipede in the family Xystodesmidae. It is found in North America. [1] [2] [3] [4]
Xystodesmidae is a family of millipedes. Its members often have very small distributional areas, with many species only known from a single locality. They are found across the northern hemisphere, with peak diversity in the Appalachian Mountains, where one-third of the 300 or so species occur. They are particularly abundant in deciduous broadleaf forests in the Mediterranean Basin, Africa, Asia, Central and North America, and Russia. Information on basic taxonomy is scant for this family; for example, it is estimated that the genus Nannaria contains over 200 species, but only 25 have so far been described.
Xystocheir is a genus of millipedes in the family Xystodesmidae. The genus is endemic to California in the United States, where it is distributed in the Coast Ranges and the Sierra Nevada.
Promecognathus is a genus of ground beetles in the family Carabidae. There are at least two described species in Promecognathus. Both species of Promecognathus are known to predate upon Xystocheir dissecta, which is a species of flat-backed millipede that produces cyanide as a chemical defense. The beetles do not avoid exposure to the defense, meaning they are likely physically resistant to cyanide.
Xystocheir dissecta is a species of flat-backed millipede in the family Xystodesmidae. It is found in North America.
Xystocheirini is a tribe of flat-backed millipedes in the family Xystodesmidae. There are about 5 genera and more than 40 described species in Xystocheirini.
