IngliżSarotherodon knauerae sp. nov. is distinguished from all congeners by the possession of an inflated second pharyngobranchial element in the upper pharyngeal jaw, and is one of the smallest known Sarotherodon, reaching a maximum observed size of only 75.2 mm SL. It further differs from sympatric S. lamprechti sp. nov. in possessing a terminal (vs. prognathous) mouth, scaled pectoral fin base, short pectoral fins ending at or in front of anus (vs. reaching first anal fin-spine or beyond) and short pelvic fins ending well in front of anus (vs. reaching anus). Additionally, S. knauerae possesses a shorter upper lip (19.1–25.4 vs. 22.5–28.4 % HL), a higher total gill raker count (24–30, mode 28 vs. 20–25, mode 22), and larger eyes (24.0–31.2 % HL, mode 27.3 vs. 20.4–29.2 % HL, mode 22.8). Distinguished from neighbouring riverine S. galilaeus populations (Cross, Wouri & Lower Niger), S. g. multifasciatus and S. g. borkuanus by a shorter anal fin (12.0–14.6 % SL vs. 15.3–19.3 % SL / 15.1–25.7 % SL and 13.4–17.9 % SL) and narrower caudal peduncle (12.8–14.5 % SL vs. 16.0–18.7 % SL / 13.9–18.3 % SL and 13.6–17.4 % SL). It differs from S. caroli and S. linnellii in higher gill raker counts (24–30 mode 28 vs. 18–20 mode 19 / 15–18 mode 18), from S. g. sanagaensis in a lower preorbital depth (17.8–23.0 vs. 25.0–27.8 % HL) and from S. g. boulengeri and riverine Sarotherodon galilaeus in a lower body depth (36.5–43.9 vs. 44.5–50.0 % SL and 43.5–44.6 % SL). Finally it differs from all other Lake Barombi Mbo Sarotherodon in a higher number of dorsal fin-rays (13 or 14, mode 13 vs. 10–12, mode 11) (Ref. 86429).

MaltiSarotherodon knauerae sp. Nov.. huwa distint mill-konġeneri kollha mill-pussess ta ' l-element pharyngobranchial tieni minfuħ fil-xedaq pharyngeal upper, u huwa wieħed mill-iżgħar magħrufa Sarotherodon, tilħaq massimu daqs ta ' biss 75.2 mm SL osservati. Tkun aktar differenti mill-sympatric S. lamprechti sp. Nov.. f li jippossjedu ħalq terminali (vs. prognathous), minquxa ġwienaħ mhux bażi, fil-qosor mhux xewk li jispiċċa fi jew quddiem il-anus (vs. jintlaħaq ewwel anal tad-denb-ispina jew lil hinn) u xewk huwa qasir li jintemm ukoll quddiem il-anus (vs. jintlaħaq anus). Addizzjonalment, S. knauerae tipposjedi a lip upper iqsar (19.1 – 25.4 vs. 22.5 – 28.4% HL), għadd raker ta-ogħla garġi totali (24 – 30, l-modalità 28 vs. modalità 20 – 25, 22), u l-għajnejn akbar (24.0 – 31.2% HL, mod 27.3 vs. 20.4 – 29.2% HL, mod 22.8). Distinti minn ġirien xmara S. galilaeus popolazzjoni (jaqsmu, Wouri & t'isfel Niger), multifasciatus tal-g. S. u S. g. borkuanus mill-ġwienaħ anal iqsar (SL 12.0 – 14.6% vs. 15.3 – 19.3% SL / 15.1 – 25.7% SL u 13.4 – 17.9% SL) u aktar dejqa kawdjali ma (SL 12.8 – 14.5% vs. SL 16.0 – 18.7% / % 13.9 – 18.3 SL u 13.6 – 17.4% SL). Tkun differenti mill- caroli ta ' S. u S. linnellii fl-ogħla garġi għadd ta ' raker (24 – 30 modalità 28 vs. 18 – 20 modalità modalità 19 / 15 – 18 18), minn S. g. sanagaensis fil-fond aktar baxx preorbital (17.8 – 23.0 vs. 25.0 – 27.8% HL) u minn S. g. boulengeri u xmara Sarotherodon galilaeus fil-fond aktar baxx korp (36.5 – 43.9 vs. 44.5 – 50.0% SL u 43.5 – 44.6% SL). Finalment tkun differenti minn kollha oħra Lake Barombi Mbo Sarotherodon f ' numru ogħla ta ' l-gangliji fin-raġġi (13 jew 14, mod 13 vs. modalità 10 – 12, 11) (Ref. 86429).
