― A new spider species, Pardosa temreshevi sp. n., collected among screes on elevation 3600 m, is described from southern Kazakhstan based on females. The new species has increased number of ventral spines on tibiae I. Pardosa temreshevi sp. n. is distantly similar to P. zhangi Song & Haupt 1995 from the highlands of Xinjiang Province (China) and distinctly differs from it by conformation of the epigyne.

Araneus is a large genus containing many species with various features, and phylogenetic analysis has revealed it to be a polyphyletic group. It has been proposed that nine new genera should be established independently from Araneus. One example is a group that includes Araneus mitificus (Simon 1886) and Araneus praesignis (L. Koch 1872). In this study, we examined specimens from several species that are morphologically similar to them, and confirmed their close relationship by phylogenetic analysis using the data of five genes. All targeted species were united in a monophyletic clade, comprising two groups in detail. The epigynes and male palps of the species in these two groups were clearly distinguishable; therefore, we concluded that they should be recognized as two independent genera. Consequently, we describe two new genera, Aoaraneus n. gen. and Bijoaraneus n. gen. Additionally, previously identified Japanese Araneus mitificus specimens were reexamined and concluded to be misidentified. It is described as a new species under the name Bijoaraneus komachi n. sp. in this study.
蜘蛛属是一个大属，包含许多种，具有不同的特征，系统发育分析表明它是一个多系群。有9个新属是独立于阿兰属之外而建立的。其中一个例子是一组包括小黄黄阿兰(Simon 1886)和praesignis阿兰(L. Koch 1872)。在本研究中，我们检查了几个物种的标本，在形态上与它们相似，并通过系统发育分析，利用5个基因的数据证实了它们的密切关系。所有的目标物种都统一在一个单系进化枝中，包括两组。在这两组中，种的表掌和雄掌有明显的区别;因此，我们认为它们应该被认为是两个独立的属。因此，我们描述了Aoaraneus n. gen和Bijoaraneus n. gen这两个新属。此外，我们还对先前鉴定的日本小黑斑阿兰(Araneus mittificus)标本进行了重新鉴定，并得出了错误鉴定的结论。本研究将其命名为Bijoaraneus komachi n. sp.。

― Scorpions can adopt different reproductive strategies (e.g., sexual or parthenogenesis) depending on the environmental conditions. In this study, we described the courtship repertoire of the parthenogenetic scorpion Tityus stigmurus , a species with inconspicuous sexual populations distributed throughout northeastern Brazil. Specimens of both sexes (10 males, 10 females) were obtained from field expeditions in three locations in northeastern Brazil and were paired under laboratory conditions in an intrapopulation design. All observations were conducted at night using red light positioned above an experimental arena. From the 10 courtship interactions observed in this study, only one pair successfully completed the reproductive repertoire that included the insemination process. The incomplete interactions were abruptly terminated by the females immediately after deposition of the spermatophore. Overall, the reproductive repertoire of T. stigmurus was similar to that of other scorpions, especially its congeners, possibly because this reproductive behavior emerged at a basal point in the evolution of scorpions. The acquisition of new insights into the reproductive biology of different scorpion species may improve the theoretical background for applications ranging from evolutionary biology to public health strategies.
