COMMENT.
Original circumscription of Etymachila should be regarded as uniting Hexapoda
+ Chilopoda + Symphyla 
,
while in the original publication Symphyla are not mentioned. According to
the original diagnosis of Etymachila, they have true labium. The labium of
Hexapoda and the "maxillae II" (actually vestiges of legs before
poison claws) of Chilopoda are similar only in belonging to the 4th
postoral segment; the gnathochilarium of Symphyla undoubtedly has the same
feature, and thus, Symphyla fall to the taxon Etymachila.
