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).

Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 6 - 7; Radios blandos dorsales (total) : 9 - 10; Espinas anales: 1; Radios blandos anales: 9 - 10. Diagnosis: posterior tip of upper jaw extends to vertical level of anterior third, or half, of eye; single row of long, slender, unicuspid setiform teeth on upper jaw, 19-49 teeth on each half (left and right) of upper jaw, separated by median tubercle (Ref. 79590). Upper lip smooth (Ref. 57403, 79590), with an inner longitudinal furrow and a small, median tubercle (fleshy swelling)(Ref. 79590). Median notch in upper lip absent or small (Ref. 79590). 3 pores in preopercular canal; flanks with checker-board arrangement of small, light and dark patches (Ref. 57403, 79590).
Body shape (shape guide): elongated.
Amphidromous endemics living as adults in clearwater streams from the rivers Lobe and Kribi, Southern Cameroon. Also from a stream located above several hundred meter high cascade of Rio Ilady, Bioko Island at an altitude of over 100m (Ref. 92840).
