Cyrthydrolaelaps Berlese

Diagnostic characters:

• Moustache-like internal malae

• Scale above 3-tined palp apotele

• Separate dorsal shields

• Acuminate ambulacral pads on legs II-IV.

Similar taxa.  Parasitidae are superficially similar to Veigaiidae, but have ventrianal shields and lack characters such as the scale-like process above the palp apotele and moustache-like internal malae.
