The genus Chorizopes (Araneae, Araneidae) includes over two dozen species of webless araneids found mainly in the Indomalayan region. They are characterised by a distinctive bulbous carapace and a specialised foraging behaviour: preying on other orb-weavers. Chorizopes casictones, sp. nov. (Araneae, Araneidae) is described based on specimens collected in northern Madagascar. This species represents the third member of Chorizopes known from the island. We conducted a total-evidence analysis based on morphology, behaviour and nucleotide sequence data, including this taxon for the first time. The palpal morphology of the male of Chorizopes is illustrated in detail. We discuss the palpal homologies and the evolution of araneid palpal sclerites based on the newly inferred family phylogenetic tree.

天体织蛛狩猎蜘蛛 Chorizo​​pes（Araneae：Araneidae）雄性触须形态的进化重新审视了 Araneidae 的新系统发育，以及对来自马达加斯加的第三种物种的描述

Chorizo​​pes 属（Araneae，Araneidae）包括超过两种无网蛛形纲动物，主要发现于 Indomalayan 地区。它们的特点是独特的球状甲壳和专门的觅食行为：捕食其他圆球编织者。Chorizo​​pes casictones，sp。十一月 （Araneae，Araneidae）是根据在马达加斯加北部收集的标本进行描述的。这个物种代表了岛上已知的 Chorizo​​pes 的第三个成员。我们根据形态、行为和核苷酸序列数据进行了全面证据分析，首次包括该分类群。详细说明了 Chorizo​​pes 雄性的手掌形态。我们讨论了基于新推断的家族系统发育树的手掌同源性和蛛形纲动物手掌骨石的进化。
