Scientific Name: Hemicycla modesta
Species Authority: (Férussac, 1821)
Taxonomic Notes: According to the pictures and description, this species appears to be very similar to H. melchori. However, this species is described from a locality far away, but also on the island of Tenerife. This case requires additional investigation.

Justification:
This species is only present in a small area which is under pressure from encroaching urbanisation, a major decline in habitat quality can be supposed. It is not clear currently whether this species is still extant or already extinct. It is known from a single location around the growing urbanisation area of Sta. Cruz de Tenerife with an area of occupancy of four km2. Thus, the species is considered as Critically Endangered, Possibly Extinct.
