Assessment Rationale:

This species is found on the edge of the city of Santa Cruz and has a severely fragmented and restricted range. It is known from only six locations. This species is assumed to be declining based on the decline of the area of occupancy due to urbanisation, as well as quarrying close to the city for building stone, road construction. This species is hence listed as Endangered (EN) B2ab(iii).

Conservation Actions

Moliner Gomez (2001) note that this species was listed on the IUCN Red List as Vulnerable A1c (Groombridge 1996) noting that a small area was occupied by this species and that the habitat was in need to protection. The species requires protection of the habitat as well as restoration of habitats to lessen the impact of fragmentation.
