Remarks.

None of the two slides in the Berlese Collection bears a type designation, but without doubt they belong to the original type series of Berlese. Unfortunately, a female on slide 208/33 is unsuitable for study and will require remounting for definitive study, whereas the female on slide 210/39 must be lost because I was unable to find any specimen or dissected structures on that slide (both slides are opaque and essentially unusable).
