Etymology: Pellonula: Latin, pellis = skin + Latin, nullus = no one (Ref. 45335);  leonensis: Species is named after the vernacular name in Bambara, 'miri', given by the local fisherman in Mali (Ref. 2756).  More on author: Boulenger.

Africa: freshwater rivers of West Africa (Ref. 188, 2244), in lagoons, lakes, lower and upper courses of rivers from Senegal to Cross River (Ref. 81269), including upper reaches of Niger and lower parts of Benue River (Ref. 188); and lagoons and lower and middle courses of coastal rivers from Cameroon to Democratic Republic of Congo (Ref. 2244, 81631), including a record in the Léfini River (Ref. 88782). Apparently not in upper parts of Congo system (Ref. 188). Also reported from Atlantic Ocean, including beaches at Hann near Dakar in Senegal and near Pointe Noire in Congo Republic (Ref. 188).

Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 0; Dorsale zachte stralen (totaal): 13-19; Anale stekels 0; Anale zachte stralen: 15 - 22; Wervels: 39 - 44. Diagnosis: This species is characterised by the first prepelvic scute being as large as the following scutes lacking ascending arms, and located behind the pectoral-fin origins, and by the inward-curving premaxillary teeth (Ref. 2244, 2849, 81269, 81631). Scutes beginning behind base of first pectoral finray; lower jaw very slightly projecting, teeth at symphysis only slightly enlarged; premaxillary teeth small, curved inward, only the tips usually apparent, no strongly marked indentation at centre of jaw; lower gillrakers 20-35, long and equal to or longer than the corresponding gill filaments; silver stripe along flank (Ref. 188, 81269). It resembles Pellonula vorax, which has larger and straighter teeth, often pointing forward, and scutes before pectoral fin bases; absence of large canine teeth in upper jaw, within or behind normal outer premaxillary series, distinguishes it from Odaxothrissa; Microthrissa species are deep-bodied and have a much more slender maxilla (Ref. 188).

Biologie     Verklarende woordenlijst (b.v. epibenthic)

Found chiefly in rivers and streams, also man-made and natural lakes (Ref. 188); also in estuaries and lagoons (Ref. 188, 2683). Apparently able to tolerate moderate or even quite high salinities (Ref. 188). It forms enormous shoals in both inshore and offshore regions of Lake Kainji (Ref. 3034). It feeds on terrestrial and aquatic insects, but also ostracods and entomostracans; stomachs containing clupeid fish scales may represent cannibalism (Ref. 188). Reproduction occurs in rivers and lakes, and may be also in estuaries and coastal lagoons (Ref. 2683). It breeds from July to September in Lake Volta (Ref. 188).
