Abstract

The southern South American genus Guaranita includes tiny spiders (body length ~1 mm) that lead reclusive lives under ground-objects and run rapidly when disturbed. As a result, they have been poorly collected and studied. Here we report on a recent collection of Guaranita spiders from Argentina, describing one new species (G. auadae Huber sp. nov.) and the previously unknown female of G. dobby Torres et al., 2016. In addition, we provide CO1 barcodes for all (now five) known species, first SEM data, and first chromosome data for the genus. The diploid number of Guaranita goloboffi Huber, 2000 (2n♂ = 11) is among the lowest in araneomorph spiders with monocentric chromosome structure.

南美蛛科蛛蛛属的修正(蛛蛛科，蛛蛛科)

南美洲南部瓜拉尼塔属包括一种微小的蜘蛛(体长约1毫米)，它们隐居在地面物体下生活，受到干扰时迅速奔跑。因此，它们被收集和研究得很差。在这里，我们报告了最近从阿根廷收集的瓜拉尼塔蜘蛛，描述了一个新物种(G. auadae Huber sp. 11 .)和G.多比托雷斯等人，2016年以前未知的雌性。此外，我们提供了所有已知物种(现在有5个)的CO1条形码，第一次扫描电镜数据和第一次染色体数据。瓜拉尼塔(Guaranita goloboffi Huber, 2000)的二倍体数(2n♂= 11)是单中心染色体蜘蛛中二倍体数最少的蜘蛛之一。

期刊介绍： EJT is a fully refereed, international, fully electronic Open Access journal in descriptive taxonomy, covering subjects in zoology, entomology, botany (in its broadest sense), and palaeontology. EJT-papers must be original and adhere to high scientific (content) and technical (language, artwork, etc.) standards. Manuscripts that are clearly substandard in either of these categories will not be sent out for review. EJT is supported by a consortium of European Natural History Institutes, but its scope is global. Both authorship and geographical region of study need not be European. Authors are, however, strongly encouraged to involve European Natural History collections by consulting material or by depositing specimens (e.g. types and figured material) related to their published paper in the collection of a European Natural History Institute.
