Raphidiophrys intermedia

Raphidiophrys intermedia  Penard, 1904

Diagnosis: Scales oblong, 7.2-12.7 µm long and 3.1-4.8 µm broad with a L/B ratio of 1.7-2.3 (mean 2.0); scales with internal radial septa; number of septa along the border varying from 29-33 per 10 µm.
Penard (1904), in diagnosing this species, describes the scales as having the shape of a parallelogram. The long sides of most scales run nearly parallel, a feature which is hardly observed among related species. Scales of other species have more convex sides. According to Penard (1904) the length of the scale is twice the breadth.

Remarks: I have collected this species both in Sweden and The Netherlands.
