This species is endemic to the coast of Angola from Benguela in the north to just north of Lucira a distance of approximately 400 km following the coast. The species is common within the range (E. Monnier pers. comm. 2011), with many locations along the coast. There are no specific current threats from urban development or other major anthropogenic factors. Oil prospecting has been carried out along Angola's coast and eventually oil exploration may have an effect on Angola's coast in the future, but there is no current development of these activities. The species has been assessed as Least Concern.
|Range Description:||This species is endemic to the coast of Angola from Benguela in the north to just north of Lucira, a distance of approximately 400 km following the coast (Monteiro et al. 2004). The species is common within the range (E. Monnier pers. comm. 2004), with many locations along the coast. The extent of its range is probably more than 400 km, with new populations found in central and south Angola (M. J. Tenorio pers. comm. 2011).|

|Population:||There are no data on the population levels for this species, but it is commonly available for sale. The maximum size of specimen is 31 mm. Together with C. aemulus, this is the most common Conus species in Angola (M. J. Tenorio pers. comm. 2011).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species has been found in sand in shallow water (Poppe and Poppe 2011) and down to 10 m in mud (Filmer 2001).|
|Use and Trade:||
The shells of this species are traded for the specialist Conus shell market only. As a result, the level of off-take is low (M. J. Tenorio pers. comm. 2011).
|Major Threat(s):||There are no known threats to this species at the present time. It occurs in central and south Angola and hence away from the capital, so that pollution is not a problem for this species (M. J. Tenorio pers. comm. 2011). Oil prospection has been going on along the Angolan coast, but there is no further development on this at the moment, so this is not considered a current threat; it may be more significant in the future if oil drilling commences (M. J. Tenorio and S. Veldsman pers. comm. 2011).|
|Conservation Actions:||There are no known conservation measures currently in place for this species.|
