Identification

-level identification relies on the Oncopodura, which exhibits diagnostic characters including: postantennal organ with 6 long subequal lobes each subdivided into 3–6 finger-like projections; dens with 7 feather-like macrosetae and specific hook arrangements; manubrium bearing long feather-like macrosetae reaching the middle of the dens; and mucro with 4 teeth and basal .
