Aphalaridae, sensu novo

Aphalarinae Löw, 1879: 606 .

Diagnosis: Adult metatibia with an open crown of sclerotised apical spurs (sometimes grouped). Larva without or with lobed tarsal arolium lacking unguitractor.

Internal phylogeny: The Aphalaridae contains five probably monophyletic subfamilies. Adult Rhinocolinae, Spondyliaspidinae and Togepsyllinae lack a horn-shaped meracanthus, which is usually tubercular but sometimes knob-like. This may constitute a synapomorphy grouping the three subfamilies. In Aphalarinae and Pachypsyllinae the meracanthus is well-developed and horn-shaped.
