Bibliography of the genus Mecistops
Biodiversity of the family Crocodylidae








Genus
Mecistops

African Slender-snouted Crocodiles, African Sharp-nosed Crocodiles

Panzerkrokodile

Panserkrokodiller

1844 Mecistops Gray (type species: Mecistops bennettii Gray 1844)

Contents: 2 species, none of which are endemic.
Endemism: 0% 100%
Remarks: Until recently regarded as a synonym of Crocodylus (e.g., Wermuth & Mertens 1977). Schmitz, Mansfeld, Hekkala, Shine, Nickel, Amato & Böhme (2003) suggested the possible future recognition of Mecistops as a valid genus. McAliley, Willis, Ray, White, Brochu, & Densmore (2006) presented evidence supporting its validity.
Distribution: Angola (incl. Cabinda), Burundi, Cameroon, Central African Republic, Congo-Brazzaville, Congo-Kinshasa, Equatorial Guinea (Rio Muni), Gabon, Gambia, Ghana, Guinea, Ivory Coast, Liberia, Nigeria, Sierra Leone, Tanzania, Togo, Zambia.

Mecistops cataphractus

West African Slender-snouted Crocodile

Westafrikanische Panzerkrokodil

Vestafrikansk Panserkrokodille

1825 Crocodilus cataphractus Cuvier
Mecistops cataphractus Gray 1844
1844 Mecistops bennetti Gray (syn. Shirley, Carr, Nestler, Vliet & Brochu 2018)
1974 Crocodylus cataphractus congicus Fuchs, Mertens & Wermuth (nomen nudum and nomen dubium; fide Shirley, Carr, Nestler, Vliet & Brochu 2018)
Mecistops cataphractus congicus McAliley, Willis, Ray, White, Brochu, & Densmore 2006 [by implication]

Remarks: Presence in many areas of the historical distribution of the species is doubtful. Considered absent in Benin, Burkina Faso, Guinea-Bissau, Mali, Mauritania, and Senegal, based on lack of recent (or any) documentation (Shirley, Carr, Nestler, Vliet & Brochu 2018). May also be extirpated in Nigeria (Shirley, Carr, Nestler, Vliet & Brochu 2018).
Introduced to: USA (Florida).
Distribution: Gambia, Ghana, Guinea, Ivory Coast, Liberia, Nigeria, Sierra Leone, Togo.

Mecistops leptorhynchus

Central African Slender-snouted Crocodile

Zentralafrikanische Panzerkrokodil

Centralafrikansk Panserkrokodille

1835 Crocodilus leptorhynchus Bennett
Mecistops leptorhynchus Shirley, Carr, Nestler, Vliet & Brochu 2018

Remarks: Previously regarded as a synonym of cataphractus (e.g., Wermuth & Mertens 1977). Revalidated as a separate species by Shirley, Carr, Nestler, Vliet & Brochu (2018). Continued presence in Angola (Cabinda) and Tanzania is uncertain (Shirley, Carr, Nestler, Vliet & Brochu 2018). Burundi is included in the distribution, based on an unconfirmed sighting (Shirley, Carr, Nestler, Vliet & Brochu 2018). Regarded as extinct in Chad (Shirley, Carr, Nestler, Vliet & Brochu 2018). A record from Bioko (Equatorial Guinea) is presumably based on a specimen caught on the mainland (Shirley, Carr, Nestler, Vliet & Brochu 2018).
Introduced to: Equatorial Guinea (Bioko).
Distribution: Angola (incl. Cabinda), Burundi, Cameroon, Central African Republic, Congo-Brazzaville, Congo-Kinshasa, Equatorial Guinea (Rio Muni), Gabon, Tanzania, Zambia.
