Diagnosis
Pachastrellidae having oxea megascleres in one or more categories along with calthrops and/or short-shafted triaenes that can be mesotriaenes. Microscleres consist of oval microstrongyles that make an ectosomal feltwork and one or several kinds of streptasters that may include forms with reduced actines; they never are microxeas.
