Arthropod symbiotes of the Laotian rock-rat, Laonastes aenigmamus (Rodentia:Diatomyidae), from Laos are examined. This host is a member of Diatomyidae previously thought to have gone extinct >10 million yr ago. Permanent symbiotes are represented by 2 species, a new species of sucking louse, Polyplax sp., near rhizomydis (Phthiraptera:Polyplacidae), and a new species of fur mite, Afrolistrophorus sp., near maculatus (Acariformes:Listrophoridae). The temporary parasites are represented by 18 species, i.e., 1 mesostigmatan species, i.e., a new species of Androlaelaps near casalis (Parasitiformes:Laelapidae); immature stages of 2 tick species, Ixodes granulatus and Haemaphysalis sp. (Parasitiformes:Ixodidae); and a rich fauna of chiggers (Acariformes:Trombiculidae) comprising 8 genera and 15 species. It is hypothesized that this host completely lost its initial fauna of ectosymbiotes and that ancestors of the recorded symbiotes switched to this host from rodents of the superfamily Muroidea.
对来自老挝的老挝岩鼠(Laonastes aenigmamus,啮齿目:硅藻鼠科)的节肢动物共生体进行了研究。这种宿主是硅藻鼠科的成员,此前被认为在1000多万年前就已灭绝。永久性共生体有2种,一种是新的吸血虱,近根鼠多板虱(Polyplax sp.,近根鼠亚种,啮虱目:多板虱科),另一种是新的皮螨,近斑点非洲列螨(Afrolistrophorus sp.,近斑点亚种,真螨目:列螨科)。临时性寄生虫有18种,即1种中气门螨类,即近卡萨利斯安德罗厉螨(Androlaelaps near casalis,新物种,寄螨目:厉螨科);2种蜱虫的未成熟阶段,粒形硬蜱(Ixodes granulatus)和血蜱属(Haemaphysalis sp.,寄螨目:硬蜱科);以及丰富的恙螨动物群(真螨目:恙螨科),包括8个属和15个物种。据推测,这种宿主完全失去了其最初的体表共生动物群,而记录的共生体的祖先从鼠总科的啮齿动物转而寄生到这种宿主身上。
