The Azores Cone-head (Conocephalus chavesi) is endemic to the Azores archipelago in Portugal. This species is assessed as Endangered since it as a restricted geographic range (area of occupancy (AOO) between 40 and 80 km²) the population is severely fragmented, and there is an inferred continuing decline in the AOO, number of subpopulations, extent and quality of the habitat as well as in the number of mature individuals. The major threat to this species is urbanisation which destroys its habitat. Protection and restoration of its remaining habitats is needed. In addition, further research is recommended on its population trend, ecology and threats.
