简单描述 型态特徵 | 形态测量图

Body moderately compressed, its depth equal to or a little greater than the length of the head (Ref. 48244). Snout rounded, shorter than the eye diameter (Ref. 48244). Anterior barbel short, posterior barbel longer, extending as far as the vertical to the mid-point of the pupil of the eye (Ref. 48244). Teeth with recurved crowns; the teeth formula 2.3.5-5.3.2 (Ref. 48244). Well developed sunken pit-lines are present on the cheek and operculum and on the dorsal surface of the head; there may be as many as 12 lines between the preoperculum and the anterior orbital margin (Ref. 48244). Scales have radiate striae (Ref. 48244): 22-25 lateral line scales, 4½-5 scales between the dorsal fin origin and lateral line, 1½-2 scales between lateral line and pelvic insertion (Ref. 48244). Lateral line complete (Ref. 48244). Dorsal fin is on or slightly in advance of the perpendicular to the pelvic fin insertion; III/7 or III/8 rays, the third unbranched ray not ossified and flexible (Ref. 48244). Anal fin has III/5 rays (Ref. 48244). The pectoral fin does not reach the base of the pelvic fin (Ref. 48244). The caudal peduncle is relative slender, its depth 1.36 to 1.76 times in its length (Ref. 48244). The post Weberian vertebral count is 27 (Ref. 48244). The upper flanks, caudal peduncle and caudal fin are orange-red colored in life (Ref. 48244). A dark midlateral stripe of varying intensity runs from the tip of the snout to the base of the caudal fin; a small, rounded black spot is at the base of the caudal fin and patches of pigment about the origin of the dorsal and on the base of the anal fin (Ref. 48244).
身体中等侧扁, 它的深度等于或稍微大于头部的长度.(参考文献 48244) 吻圆的, 短于眼直径.(参考文献 48244) 前面的触须短又在后部的触须更长的, 遥远地延伸到眼的瞳孔的垂直到中央点.(参考文献 48244) 牙齿有后弯的冠; 齿公式 2.3.5-5.3.2.(参考文献 48244) 下沉凹洞的发展良好的-线在颊部与鳃盖与头部的背部表面上出现; 在哪里可能是在前鳃盖骨与前面的眼窝边缘之间的多达 12条行。 (参考文献 48244) 鳞片有放射的陷纹:(参考文献 48244) 22-25个侧线鳞片,4?在背鳍起源与侧线之间的 -5个鳞片,1?在侧线与腹鳍嵌入之间的 -2个鳞片.(参考文献 48244) 侧线完整.(参考文献 48244) 背鳍是或者之上在那略前方垂直于腹鳍嵌入; 3/7 或 3/8个鳍条, 第三个不分枝的鳍条不钙化了与柔韧有弹性的.(参考文献 48244) 臀鳍有 3/5个鳍条。 (参考文献 48244) 胸鳍不会到腹鳍基底。 (参考文献 48244) 尾梗是相关的细长, 它的深度 1.36 到 1.76 倍于体长.(参考文献 48244) 后 Weberian 脊椎骨数是 27 。 (参考文献 48244) 上面的侧面, 尾柄与尾鳍鳍是橘红色的色彩活着时.(参考文献 48244) 从吻尖到尾鳍基底改变强烈的深色侧面中央斑纹; 在尾鳍基底与有颜色的区块的一个小的, 圆形的黑色斑点是大约背部的起源与在臀鳍的基底上.(参考文献 48244)

生物学特性     字汇 (例如 epibenthic)

Type specimens of Barbus venustus were caught in shallow water among open stands of the emergent grass Paspalidium geminatum in the Nyumba ya Mungu reservoir; it was taken in July and August at the onset of the dry season but with the lake level still close to its maximum (Ref. 48244). Gut content includes cladocerans, insect fragments, plant material and fine sand (Ref. 48244).

Barbus venustus 的模式标本在 Nyumba ya Mungu 水库于在突出草 Paspalidium geminatum 的开放台子之中的浅水区捕获; 它在七月与八月采集在干季但是有的开始湖面仍接近它的极大.(参考文献 48244) 消化道内容包括水蚤,昆虫碎片,植物与细砂。 (参考文献 48244)
