Motyxia Chamberlin由8种发光剑手类千足虫组成，其生殖足管节发生在不同的位置，从基部和近基部的端足到与同伴的端足分支融合并在近端或近中部分离。以前的同义词Amplocheir Chamberlin和Luminodesmus卢米斯和达文波特根据Motyxia被确认为是其分配到部落Xystocheirini，这是重新定义。组成种为M. kerna Chamberlin，模式种，monica Chamberlin，Sequoiae（卢米斯和达文波特），tularea（Chamberlin），Sequoia（Chamberlin），pior Chamberlin，porrecta Causey and Tiemann，and tiemanni Causey. Motyxia Sequoia由两个种族组成，即提名种族和Sequoia阿利亚Causey和Tiemann; Sequoia ollae Causey和Tiemann实际上是土拉雷亚的一个亚种。Motyxia pior form secca是一个不符合命名法的无效名称，M. tejona Chamberlin和M. expansa和exilis，两者都是卢米斯的，都放在M. monica是最南端物种的最古老的名称，因为Polydesmue dissectus Wood与Xystocheir Cook相似。生物发光是指包括触角和腿在内的整个背表面的连续的、乳白色的发光。它在夜间的可见度表明了类似于警戒色的警告功能。这种现象可以观察到昼夜节律，控制光周期实验可能是富有成效的。
Motyxia Chamberlin is comprised of eight species of bioluminescent xystocheirine millipeds in which the gonopodal solenomere arises at different positions, from basally and subbasally on the acropodite to being fused with the companion acropodal branch and detaching proximad or near midlength. Previous synonymies of Amplocheir Chamberlin and Luminodesmus Loomis and Davenport under Motyxia are confirmed as is its assignment to the tribe Xystocheirini, which is redefined. Component species are M. kerna Chamberlin, the type species, monica Chamberlin, sequoiae (Loomis and Davenport), tularea (Chamberlin), sequoia (Chamberlin), pior Chamberlin, porrecta Causey and Tiemann, and tiemanni Causey. Motyxia sequoia is comprised of two races, the nominate and sequoia alia Causey and Tiemann; sequoia ollae Causey and Tiemann is properly a subspecies of tularea. Motyxia pior form secca is an invalid name without standing in nomenclature, and M. tejona Chamberlin, and M. expansa and exilis, both by Loomis, are placed in synonymy under M. monica, the oldest name for the southernmost species, as Polydesmue dissectus Wood is referrable to Xystocheir Cook. The bioluminescence is a continuous, neon-white glow of the entire dorsal surface including the antennae and legs. Its visibility at night suggests a warning function analogous to aposematic coloration. The phenomenon may observe a circadian rhythm, and controlled photoperiod experimentation may be productive.
