Etymology: Sicydium: Greek, sika, sikya = cucumber ; diminutive (Ref. 45335).
Eponymy: Gabriel de Bustamenté was a Brazilian slave trader on São Tomé Island, Gulf of Guinea. His occupation did not stop Greef describing him as the ‘hospitable and intelligent’ (translation) owner of a farm situated on São Tomé. (Ref. 128868), visit book page.
Issue
This species is validated by Risch et al. (1979: Ref. 89459) who found the types, thus it is not a nomen nudum and the name is available. The species is confirmed under this name by Pezold et al. (2006: Ref. 59380). Therefore, the species should not be attributed to Boulenger, 1916 (as Sycidium bustamantaei).

Eastern Atlantic: islands of Bioko, Sao Tome, Principe and Pagalu (= Annobon) in the Gulf of Guinea, up to altitudes of 1,200 m; might also occur in the Lobe and Kribi Rivers of Cameroon, but this requires confirmation (Ref. 79590).
