Abstract

A new genus and species, Chicosciencea pernambucensisgen. nov., sp. nov., is described from two localities along the coast of Pernambuco state, northeastern Brazil. Considering the unresolved situation of the families of Stenopodidea in previous studies, the position of this new genus is discussed based on morphological, molecular (16S mtDNA), and ecological data. The morphological analysis revealed that Chicoscienceagen. nov. differs from all stenopodidean genera by a combination of characters. The inferred molecular phylogeny recovered a monophyletic group including Chicoscienceagen. nov., MacromaxillocarisAlvarez, Iliffe & Villalobos, 2006, and MicroprosthemaStimpson, 1860, which comprise free-living (i.e., not-sponge associated), shallow-water species. Based on this monophyletic group and on their morphological and ecological similarities, we herein formally propose the resurrection of Macromaxillocarididae Alvarez, Iliffe & Villalobos, 2006 to include those genera. We also provide an updated world list of Stenopodidea. With the description of Chicoscienceagen. nov., the infraorder Stenopodidea now comprises 13 genera and 92 species.

复活的Macromaxillocarididae Alvarez家族的巴西新属和种，Iliffe和Villalobos，2006年，以及剑尾足纲目（十足目）的全球清单

摘要

一个新的属和种，伯南茅（Chicosciencea pernambucensis）属。十一月 ，sp。nov。，是从巴西东北部伯南布哥州沿海的两个地方描述的。考虑到以前的研究中剑齿纲的未解决情况，根据形态学，分子（16S mtDNA）和生态学数据讨论了该新属的地位。形态分析揭示了Chicosciencea gen。年11月。在字符组合方面与所有斜纹夜蛾属不同。推断的分子系统发育恢复了包括Chicosciencea gen在内的单系统群体。11月，Macromaxillocaris Alvarez，Iliffe和Villalobos，2006年，以及Microprosthema Stimpson，1860年，其中包括自由活动（即与海绵无关）的浅水物种。基于这个单族群及其形态和生态上的相似性，我们在此正式提议Macromaxillocarididae Alvarez，Iliffe＆Villalobos，2006的复活包括这些属。我们还提供了Stenopodidea的更新的世界列表。随着Chicosciencea gen的描述。到了11月，下层视剑目（Snopoodidea）现在包括13属和92种。
