Abstract:
Four new inquiline social parasites are described in the dolichoderine ant genus Tapinoma from the Nearctic region, and keys are provided for queens and males of the Nearctic Tapinoma species. The new social parasite species represent the first inquiline species in the genus Tapinoma and the first confirmed inquilines known from the ant subfamily Dolichoderinae. The four new species appear to be workerless inquilines that exploit a single host, Tapinomasessile (Say), and they represent at least two distinct life history syndromes. Tapinomaincognitum Cover & Rabeling, sp. nov. is highly derived morphologically and is a host-queen-tolerant inquiline. In contrast, T.inflatiscapus Cover & Rabeling, sp. nov. shows a lesser degree of morphological modification and appears to be a host-queen-intolerant social parasite. The life history of T.pulchellum Cover & Rabeling, sp. nov. is presently unknown, but its close similarity to T.incognitum suggests that it is also a host-queen-tolerant inquiline. The life history of T.shattucki Cover & Rabeling, sp. nov. is still uncertain. Our findings provide novel insights into the complex biology of ant inquiline life history syndromes.
摘要:
在Nearctic地区的dolichoderine蚂蚁属Tapinoma中描述了四种新的犯罪社会寄生虫,并为近缘Tapinoma物种的皇后和雄性提供钥匙。新的社会寄生虫物种代表了Tapinoma属中的第一个acquiline物种,以及从蚂蚁亚科Dolichoderinae中已知的第一个已确认的acquiline物种。这四个新物种似乎是利用单一宿主的无工作动物,Tapinomasessile(说),它们至少代表两种截然不同的生活史综合征。TapinomaincognitumCover&Rabeling,sp.11月。在形态上是高度衍生的,是一种对女王宽容的审讯者。相比之下,T.inflatiscapusCover&Rabeling,sp.11月。显示较小程度的形态修饰,似乎是宿主-女王-不耐受的社会寄生虫。T.PulchellumCover和Rabeling的生活史,sp.11月。目前未知,但是它与T.incognitum非常相似,这表明它也是一种宽容女王的犯罪。T.shattucki封面和拉伯林的生活史,sp.11月。仍然不确定。我们的发现提供了新的见解的复杂生物学的主动生活史综合征。
