Pruvot-Fol's description based on preserved specimens from Morocco, contains no worthwhile anatomical information and the colour of the living animal is based on the two paintings reproduced here.

Dear Erwin and Bill,
Yes, this species is Berthella africana. This species was erected by Pruvot-Fol (1953) as Berthellina, but later Gantes (1956) explain the confusion that happened and transferred the species to Berthella.
You can find a more detailed history of the problem in Cervera et al (2000). J.Moll. Stud., 66: 3001-311.

It would be interesting to have a photo of your Berthella canariensis on the Forum for comparison. I have included scans of the original paintings included in Pruvot-Fol's original description on the Fact Sheet.

Here is one more from Gran Canaria, Canary Islands. Arthur J. Telle (Email email@example.com) labels it Berthella africana, can you confirm this ID?

I can't find a reference to Berthella africana. Perhaps Lucas Cervera will be able to help us out
