Abstract：
With 76 currently valid species, the bushynose catfish genus Ancistrus is the fourth most species-rich catfish genus, yet Ancistrus diversity remains underestimated, with many species still undescribed. This is especially true of the Peruvian Andean headwaters of the Amazon, which are rich in unnamed Ancistrus species but have received little recent taxonomic attention. We describe a distinctively striped new Ancistrus species from tributaries of the Palcazú River, in the Pachitea-Ucayali-Amazonas drainage basin. The new species differs from all congeners by having black, vermiculated lines covering the head and two to four distinct black, parallel, lateral body stripes from head to caudal fin (vs. body uniformly colored or with dark or light spots or blotches over head and body, or black vermiculate lines on flanks). The new species is the fifth valid species of Ancistrus described from the rich Ucayali River ichthyofauna. It has previously been recognized in the aquarium fish trade as L267.
摘要：
目前有76个有效物种，马尾鼻cat鱼属Ancistrus是第四大种类丰富的cat鱼属，然而Ancistrus的多样性仍然被低估，许多物种仍未被描述。对于亚马逊的秘鲁安第斯源头尤其如此，它们富含未命名的Ancistrus物种，但最近很少受到分类学的关注。我们描述了来自帕尔卡祖河支流的一种独特条纹的新Ancistrus物种，在Pachitea-Ucayali-Amazonas流域。新物种与所有同类物种的不同之处在于具有黑色，覆盖头部的蛭状线条和两到四个明显的黑色，平行,从头部到尾鳍的外侧身体条纹(vs.身体均匀着色或头部和身体上有深色或浅色斑点或斑点，或侧面的黑色蛭状线条)。新物种是从丰富的Ucayali河鱼鱼中描述的Ancistrus的第五个有效物种。以前在水族馆鱼类贸易中被认为是L267。
