Abstract

Abstract Two new species of Bujurquina are described from the Bolivian Amazon basin. The first new species inhabits the Beni River drainage and is distinguished from its congeners in the combination of the following characters: longer snout, deeper head, body and caudal peduncle, shorter pectoral fin, more scales in the E1 series, discontinuous longitudinal band, bars 5 and 6 not fused, preopercular spot and coloration pattern on flank scales absent. The second new species inhabits the Mamoré and Iténez river drainages, and differs from its congeners in the combination of the following characteristics: longer and deeper head, longer snout and pectoral fin, deeper caudal peduncle, fewer scales in the E1 series and lower lateral line, preopercular spot absent, bars 6 and 7 separated from longitudinal band and discontinuous longitudinal band. An identification key for species reported from Bolivia and complementary morphological data for B. oenolaemus and B. vittata are presented.

文章标题玻利维亚亚马孙地区布丘尔奎纳二新种记述(Teleostei: chichlidae)

摘要描述了玻利维亚亚马逊盆地布尤尔奎纳属的两个新种。第1个新种生活在贝尼河流域，其特征与同类的区别在于:口部较长，头、身、尾花梗较深，胸鳍较短，E1系列鳞片较多，纵带不连续，5条和6条不融合，侧面鳞片无眼前斑点和彩色图案。第二新种生活在mamor河和itacimnez河流域，与同属物种的不同之处是:头长而深，鼻和胸鳍较长，尾柄较深，E1系列鳞片较少，侧线较低，眼前斑缺失，6和7条与纵带分离，纵带不连续。本文给出了玻利维亚报告物种的鉴定关键字，并对两种物种的形态资料进行了补充。

期刊介绍： Neotropical Ichthyology is the official journal of the Sociedade Brasileira de Ictiologia (SBI). It is an international peer-reviewed Open Access periodical that publishes original articles and reviews exclusively on Neotropical freshwater and marine fishes and constitutes an International Forum to disclose and discuss results of original research on the diversity of marine, estuarine and freshwater Neotropical fishes. -Frequency: Four issues per year published only online since 2020, using the ‘rolling pass’ system, which posts articles online immediately as soon as they are ready for publication. A searchable and citable Digital Object Identifier (DOI) is assigned to each article immediately after online publication, with no need to await the issue’s closing. -Areas of interest: Biology, Biochemistry and Physiology, Ecology, Ethology, Genetics and Molecular Biology, Systematics. -Peer review process: The Editor-in-Chief screens each manuscript submitted to Neotropical Ichthyology to verify whether it is within the journal’s scope and policy, presents original research and follows the journal’s guidelines. After passing through the initial screening, articles are assigned to a Section Editor, who then assigns an Associate Editor to start the single blind review process.
