Pseudobarbusverloreni, a new species, is described from material collected in the Verlorenvlei River system on the west coast of South Africa. It differs from its congeners (except Pseudobarbusskeltoni, Pseudobarbusburchelli, and Pseudobarbusburgi) by the presence of two pairs of oral barbels. Pseudobarbusverloreni sp. n. can be distinguished from the three currently described double barbeled Pseudobarbus species by the following combination of characters: pigment pattern, generally deeper body relative to standard length, a longer intestine associated with the deeper body form, shorter snout relative to head length, and much shorter anterior barbels relative to head length. The new species is distinguished from Pseudobarbusburgi in the neighbouring Berg River system by its longer head and longer pre-dorsal length. It seems as if Pseudobarbusverloreni sp. n. has been extirpated from the Langvlei River system and face several threats to its survival in the Verlorenvlei River system.
新物种维氏准魮(Pseudobarbus verloreni)是根据在南非西海岸维洛伦夫莱河水系采集的标本描述的。它与同属其他物种(除斯氏准魮、布氏准魮和伯格准魮外)的区别在于有两对口须。维氏准魮新种可通过以下特征组合与目前已描述的三种双须准魮物种区分开来:色素模式、相对于标准长度通常更深的身体、与更深身体形态相关的更长肠道、相对于头长更短的吻部以及相对于头长更短得多的前须。新物种与邻近伯格河水系的伯格准魮的区别在于其头部更长且背前长度更长。似乎维氏准魮新种已在朗夫莱河水系灭绝,并且在维洛伦夫莱河水系面临着若干生存威胁。
