Mike Dale says: In solandriana the sterigma are wider and flat topped compared to brunnichana which are narrow, elliptical with usually a small indentation on the apex.
The signa in solandriana are both placed towards the bottom of the corpus bursa and orientated horizontally, whereas in brunnichana there is one much higher in the corpus bursa and both are orientated at a 45 degree angle approx. Razowski* (plate 68) appears to indicate this, but Nel** (planche 98) does not, and the feature should be used with caution.

Note:
Some sources (e.g. Razowski; Nel) state or show the signum lacking in rosaceana and this has led to its presence or absence being used to separate this species from rufana. The above two examples of rosaceana show a signum and it may be more reliable to use the shape of the sterigma, which is complex and compact in rosaceana (A) and crossbow-shaped in rufana (B).

The bursa copulatrix appears longer and narrower in janthe than in janthina (these are unmated examples)
From France, Bulgaria and Germany
The ratio of the length:breadth of the bursa copulatrix (length measured from the anterior sclerotised margin of the ductus bursae to the apex of the bursa copulatrix; breadth at widest point) gives 3.6-4.5 in N.janthina and 5.5-5.7 in N.janthe.
