Another problem is that some of the subfamilies recognized lack external characters useful for dichotomous keys or gestalt recognition: many features used in the morphology data matrix require extensive dissection, and those in the total evidence analysis are partly molecular. More species need to be sampled for phylogenetic study – especially those with DNA sequencing data – even though total evidence analysis has so far yielded conflicting results. They also have a usually dense moustache of stiff bristles on the face; this is called the mystax, a term derived from the Greek mystakos meaning "moustache" or "upper lip".
