Etymology: nguti: Named for the village Nguti in Southwestern Cameroon where the majority of the type series was collected; noun in apposition (Ref. 49597).
Environment: milieu / climate zone / depth range / distribution range
生態学
; 新鮮な水 底生の漂泳性; 深さの範囲 0 - 2 m (Ref. 49597). Tropical
Africa: only known from the type localities in the region of Nguti in the Mamfue River, a tributary of the upper Cross River, Cameroon (Ref. 52307, 81260).
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 5.5, range 5 - 6 cm
Max length : 13.3 cm SL オス/雌雄の選別がない; (Ref. 49597); 7.3 cm SL (female)
背面の脊椎 (合計) : 15; 背鰭 (合計) : 10; 肛門の骨: 3; 臀鰭: 7 - 8; 脊つい: 25. Diagnosis: 2 supraneural bones; scaleless, darkly pigmented blotch on dorsocaudal field of opercle; cuspidate oral jaw dentition; some or all teeth tricuspid in outer row oral dentition (Ref. 49597, 52307). Upper lip with crease (Ref. 49597). Spinous dorsal fin deeply excavated dorsally (Ref. 49597, 52307). Strongly marked oblique black bar anterior on body in preserved specimens; mouth small and slightly inferior (Ref. 49597).
Juveniles were collected with beach seine in the shallow inshore zone in a water depth of few centimeters, adults in deeper water; juveniles prefer shallow water riffles with medium current, while adults congregate around submerged tree branches and rocky outcrops (Ref. 49597). Mainly feeds on detritus, occasionally on insects and plants (Ref. 52307). Delayed uptake, ovophilic (Ref. 81260), larvophilic (Ref. 52307) mouthbrooder (Ref. 52307, 81260) that does not pair-bond (Ref. 52307), spawning in couples over open substrate (Ref. 49597). Female (rarely the male) incubates the fry (Ref. 49597, 52307).
