本文报道的蜘蛛Parasteatoda tepidariorum（C. L. Koch，1841; syn.：茶背希蛛（Achaearanea tepidariorum）是发育生物学、进化和遗传学研究的重要对象。近年来，它已成为除沙氏铜盘鱼外的一种螯合模式生物。然而，仍然需要一个考虑到整个发展的分期系统，并且足够详细以适用于现代研究。在这里，我们描述了P. tepidariorum的胚胎发育，并提供了一个分期系统，使用简单的实验室工具可以轻松识别不同的阶段。与其他螯形动物的差异主要是C. Salei，讨论。此外，还描述了产茧和胚后第一次换羽过程。所有阶段的示意图提供，以方便阶段识别。
The cobweb spider Parasteatoda tepidariorum (C. L. Koch, 1841; syn.: Achaearanea tepidariorum) has become an important study organism in developmental biology and evolution as well as in genetics. Besides Cupiennius salei, it has become a chelicerate model organism for evo-devo studies in recent years. However, a staging system taking into account the entire development, and detailed enough to apply to modern studies, is still required. Here we describe the embryonic development of P. tepidariorum and provide a staging system which allows easy recognition of the distinct stages using simple laboratory tools. Differences between P. tepidariorum and other chelicerates, primarily C. salei, are discussed. Furthermore, cocoon production and the first postembryonic moulting procedure are described. Schematic drawings of all stages are provided to ease stage recognition.
