摘要

摘要蜘蛛Myrmecicultor chihuahuensis Ramírez, Grismado & Ubick (Myrmecicultoridae)于2019年被描述，并被假设为一种亲蜜蚁，生活在Novomessor (Myrmicinae)的巢穴中，也可能是Pogonomyrmex (Myrmicinae)蚂蚁。为了验证奇瓦huensis是其宿主蚂蚁的化学模仿者的假设，我们进行了行为生物测定来观察蜘蛛和宿主蚂蚁之间的相互作用。我们比较了蜘蛛和蚂蚁的表皮碳氢化合物(CHC)谱。我们发现这种新蜘蛛是一种食蜜蜘蛛，其狩猎策略与其他食蜜蜘蛛，特别是Zodarion Walckenaer, 1826 (Zodarion Walckenaer)属的蜘蛛相似。chihuahuensis的CHC谱与与其相关的蚂蚁Novomessor albisetosus (Mayr)的CHC谱不匹配，但蚂蚁和蜘蛛共有几种化合物，可能与物种识别有关。

Trophic specialization of a newly described spider ant symbiont, Myrmecicultor chihuahuensis (Araneae: Myrmecicultoridae)

Abstract. The spider Myrmecicultor chihuahuensis Ramírez, Grismado & Ubick (Myrmecicultoridae) was described in 2019 and hypothesized to be a myrmecophile, living inside the nests of Novomessor (Myrmicinae) and perhaps also Pogonomyrmex (Myrmicinae) ants. To test the hypothesis that M. chihuahuensis are chemical mimics of their host ants, we carried out behavioral bioassays to observe interactions between the spiders and the host ants. We compared the cuticular hydrocarbon (CHC) profiles of the spiders and the ants. We discovered that this new species of spider is a myrmecophage, displaying hunting strategies similar to other myrmecophagous spiders, particularly those in the genus Zodarion Walckenaer, 1826 (Zodariidae). The CHC profile of M. chihuahuensis did not match the profile of the ants with which it associates, Novomessor albisetosus (Mayr), but ants and spider shared several compounds, potentially involved in species recognition.
