IngliżDiagnosis: mouth terminal; one pair of barbels or none (Ref. 81639). West African specimens usually without barbels, but some adults may have one or two more or less well developed pairs; anterior barbel missing or not reaching to anterior margin of eye; posterior barbel missing or not reaching to anterior margin of eye; last simple dorsal-fin ray smooth on hind margin (Ref. 81282). 2-3 large gill rakers followed by undifferentiated papillate tissue on lower limb of first gill arch (Ref. 81639). Scale formula 3.5-4.5/22-25/2.5-3.5; 1.5 scales between lateral line and pelvic-fin insertions; 9-10 scales around caudal peduncle; lateral line usually incomplete; 8 branched dorsal fin rays (Ref. 81282, 81639). Lateral line deeply depressed below dorsal fin and lateral line scales deeper than other scales; maximum reported size 28 mm SL; dorsal fin colorless; 3 small black spots aligned along middle of sides, one at end of caudal peduncle, other 2 below origin and below end of dorsal-fin base, respectively (but some of these spots may occasionally be missing) (Ref. 2940, 81282).
Description: small species; mouth terminal and oblique, its angle located approximately below centre of eye (Ref. 81282, 81639). Development of barbels occurs at late stage in Nile basin (Ref. 50093), where largest specimens may have two pairs of well-developed barbels (Ref. 81282). In West Africa majority of individuals lack barbels, except for some specimens that had been classified in different species (B. gourmanensis and B. karoualensis, which have two pairs of barbels) (Ref. 2940, 81282). 3.5-4.5 scales between lateral line and dorsal fin origin; 2.5-3.5 scales between lateral line and mid-belly; 22-25 scales in lateral line; 1.5 scales between lateral line and pelvic fin insertion; D:III,8; A:III,5; P:13; V:8 (Ref. 81282, 81639).
Coloration: yellowish-white in life; fine, black longitudinal line and 3 small, rounded spots aligned along middle of sides; 1st before level of fir

MaltiDjanjosi: ħalq terminali; par wieħed ta ' barbels jew xejn (Ref. 81639). Kampjuni tal-punent Afrikani normalment mingħajr barbels, imma xi adulti jistgħu jkollhom waħda jew żewġ pari ukoll aktar jew inqas żviluppati; barbel anterjuri nieqes jew ma laħqux mal-marġini anterjuri tal-għajnejn; barbel posterjuri nieqes jew ma laħqux mal-marġini anterjuri tal-għajnejn; aħħar sempliċi dorsali denbu ray bla xkiel fuq il-marġini billi (Ref. 81282). 2-3 garġi kbar rakers segwita minn tessut papillate mhux iddifferenzjati fuq limb aktar baxxi ta ' l-ewwel garġi arch (Ref. 81639). Skala formola 3.5-4.5/22-25/2.5-3.5; 1.5 mwieżen bejn linja laterali u pelviċi denbu inserzjonijiet; 9-10 skali madwar kawdjali ma; linja laterali normalment mhux kompluta; 8-gangliji tal ġwienaħ raġġi (Ref. 81282, 81639). Linja laterali ferm baxxi taħt gangliji ġwienaħ u l-linja laterali iskali aktar profond minn skali oħra; massimu rapportati daqs SL 28 mm; tad-denb tal-gangliji colorless; 3 tikek żgħar iswed allineati matul in-nofs tal-ġnub, wieħed f'tarf ta kawdjali ma, oħra 2 hawn taħt oriġini u taħt l-iskop tal-bażi dorsali denbu, rispettivament (iżda dawn it-tikek xi kultant jistgħu jkunu nieqsa) (Ref. 2940, 81282).
Deskrizzjoni: speċi żgħar; ħalq terminali u djagonali, angolu tiegħu jinsabu madwar taħt iċ-ċentru ta ' l-għajnejn (Ref. 81282, 81639). Żvilupp ta ' barbels jseħħ l-istadju tard fil-baċin nil (Ref. 50093), fejn kampjuni akbar jistgħu jkollhom żewġ pari ta ' l-barbels żviluppati (Ref. 81282). Fil-maġġoranza ta ' l-Afrika tal-punent ta ' l-barbels ta ' nuqqas ta ' individwi, ħlief għal xi kampjuni li kien klassifikat fl ispeċje differenti (B. gourmanensis u B. karoualensis, li jkollhom żewġ pari ta ' l-barbels) (Ref. 2940, 81282). 3.5 skali ta '-4.5 bejn linja laterali u ġwienaħ gangliji ta ' l-oriġini; 2.5 mwieżen-3.5 bejn linja laterali u ż-żaqq tan-nofs; 22-25 skali fil-linja laterali; 1.5 mwieżen bejn linja laterali u huwa ġwienaħ inserzjoni; D:III, 8; A:III, 5; P:1
