Habitat and Ecology
This species has been recorded from rocky habitats along the north coast, where the species may well have been associated with sea-urchin holes in shallow waters. The majority of habitats along this part of the coast have been disturbed, and the populations are thought to have been lost, and there have been no specimens collected since the 1980s (M.J. Tenorio pers. comm. 2011). Adults of the species typically grow 20 mm in length.

If the populations along the eastern shores of S Vicente and along the south-western coast of the nearby island of Santa Luzia that were originally considered as C. murichae are re-classified as C lugubris (Monteiro et al. 2004), then the species assessment will need to be revised.
This species is endemic to the island of SÃ£o Vicente, Cape Verde, where it is restricted to a 9 km stretch of coast.
The Cape Verde islands are experiencing a major increase in tourism. The island of SÃ£o Vicente to which this species is restricted is similarly affected with the centre of its small distribution coinciding with the town of Salamansa.
An international airport was opened on the island in 2009 to assist in the tourism development.
