摘要

第二种棘皮犀来自巴西亚马逊盆地普鲁斯河下游的支流。棘角头蛛是一种新物种，其鳍鳐数量的减少使其与所有其他无刺目物种不同：四条胸鳍鳐（与五条或更多条相比）、两条背鳍鳐，和9条尾鳍鳐（对10条，除了Hoplomyzontinae、Amaralia、Platystacus、Bunocephalus chamaizelus和Bunocepharus minerim）。使用清理和染色的标本和高分辨率x射线计算机断层扫描（HRXCT）描述了新物种棘皮虫的骨学方面，并将其与棘皮虫和其他蜘蛛目进行了比较。基于假定的apomorphic共享特征进行了属性分配，并提出了棘突的形态学诊断。

A New Miniature Species of Acanthobunocephalus (Silurifomes: Aspredinidae) from the Lower Purus River Basin, Amazon Basin, Brazil

A second species of Acanthobunocephalus is described from tributaries of the lower Purus River in the Amazon Basin, Brazil. Acanthobunocephalus scruggsi, new species, is distinguished from all other aspredinid species by its reduced number of fin rays: four pectoral-fin rays (vs. five or more), two dorsal-fin rays (vs. three or more, except Amaralia hypsiura), five pelvic-fin rays (vs. six), four to five anal-fin rays (vs. six or more, except Bunocephalus verrucosus), and nine caudal-fin rays (vs. 10, except Hoplomyzontinae, Amaralia, Platystacus, Bunocephalus chamaizelus, and Bunocephalus minerim). Osteological aspects of the new species of Acanthobunocephalus are described using cleared and stained specimens and high-resolution x-ray computed tomography (HRXCT), and compared with Acanthobunocephalus nicoi and other aspredinids. Generic assignment is based on putative apomorphic shared features and a morphological diagnosis for Acanthobunocephalus is presented.

期刊介绍： Founded in 1913, Copeia is a highly respected international journal dedicated to the publication of high quality, original research papers on the behavior, conservation, ecology, genetics, morphology, evolution, physiology, systematics and taxonomy of extant and extinct fishes, amphibians, and reptiles. Copeia is published electronically and is available through BioOne. Articles are published online first, and print issues appear four times per year. In addition to research articles, Copeia publishes invited review papers, book reviews, and compiles virtual issues on topics of interest drawn from papers previously published in the journal.
