|Scientific Name:||Conus alconnelli|
|Species Authority:||da Motta, 1986|
|Taxonomic Notes:||The taxonomic status of this species is uncertain. Moolenbeek and Coomans (1987) propose that Conus alconnelli is a synonym of Conus martensi. Tenorio et al. (2008) conclude that differences in colour and shape justify Conus alconnelli as a separate species.|

This species is endemic to Eastern South Africa where specimens have been found between Gipsy Hill (St Lucia) in the north and Port Shepstone in the south. Although this species has a relatively restricted range and has been described as being very rare, recent new populations have been discovered and the deep water habitat and inaccessibility of this species makes it unlikely to be threatened at present. It is considered to be Least Concern.
|Range Description:||This species occurs between 60-143 m, and is endemic to Eastern South Africa. However, specimens have been recorded off the coast of Oman, and in the Mahajanga region of Madagascar (Tenorio et al. 2008), but this may refer to the proposed synonymy by Moolenbeek and Coomans which has not been accepted. In eastern South Africa specimens have been found between Gipsy Hill (St Lucia) in the north and Port Shepstone in the south (GBIF 2011). Further research is needed into this species' full distribution.|

|Population:||There are no population data records for this species. New populations have recently been discovered (S. Veldsman pers. comm. October 2011).|
|Habitat and Ecology:||
This species is found in waters between 60-143 m off the East coast of South Africa in sandy substratum (Tenorio and Monteiro 2008).
Typical adult size for shells of this species are between 40-90 mm (www.theconecollector.com).
|Use and Trade:||
In common with all other molluscs, the shells of this species are traded for the collector market. There are no quantitative data on the number of shells collected.
Limited availability of shells of this species for sale on the mollusc shell market as reported through specialist websites and shell dealer catalogues (Rice 2007), with very high prices demanded may reflect their deep habitat. There is reference to this species being very rare on collector websites (Poppe and Poppe 2011).
|Major Threat(s):||There are no known material threats to this species. Because of the deep habitat, it is unlikely to be susceptible to threats of pollution and overcollection. The species is usually dredged by small boats.|
|Conservation Actions:||This species' range incorporates the St Lucia Marine Protected Area (http://protectedplanet.net). It is in deep and inaccessible habitats, so that little is known about its full distribution and ecology. Further research may therefore be beneficial. Natal has strict legislation on collection of the species (S. Veldsman pers. comm. October 2011).|
