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.

Thanks Lucas,
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.

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