A revision of Centruroides margaritatus and some of its closely related species

Acosta, Teruel and Kovarik have recently published a revision of the South American scorpion Centruroides margaritatus (Gervais, 1841) (Buthidae) and some of its closely related species. Here are some important conclusions:

Centruroides edwardsii (Gervais, 1843) is restored as valid species and its distribution is Mexico through Colombia, but without any reliable records from Guatemala, Belize and Panama. Introduced populations are reported from Cuba and Senegal (Africa).

Centruroides morenoi (Mello-Leitao, 1945) is synonymized with C. margaritatus (Gervais, 1841).

Confirmed distribution of Centruroides margaritatus (Gervais, 1841) is northwestern South America (Peru, Ecuador & Colombia). The species is also introduced to Cuba and Jamaica.

Centruroides edwardsii (Gervais, 1843) comb. nov. is restored as a valid species, and a male neotype from Riohacha, La Guajira Department, Colombia is herein designated; this species ranges from Mexico through Colombia, but there are no reliable records from Guatemala, Belize, and Panama; introduced populations also occur in Cuba (West Indies) and Senegal (Africa). We regard the following species as its junior synonyms: Scorpio (Atreus) degeerii Gervais, 1844, Centrurus gambiensis Karsch, 1879, Centruroides margaritatus septentrionalis Hoffmann, 1932, and Rhopalurus danieli Prado et Rios-Patiño, 1940. We also consider Centruroides margaritatus morenoi Mello-Leitão, 1945 as a junior synonym of Centruroides margaritatus (Gervais, 1841). After these taxonomic changes, the confirmed distribution of C. margaritatus includes northwestern South America (Peru, Ecuador, and Colombia), and the West Indies (introduced in Cuba and Jamaica).
