摘要

摘要2012年，在蒙大拿州鲍勃·马歇尔荒野地区南半部的一次骑马旅行中，采集了83份苔藓和/或地衣样本。从样品中回收了代表五科、十属和十一种的Tardigrades。两个是蒙大拿州的新手，一个是科学界的新手。将蒙大拿缓步动物的生物多样性提高到23。新种Platicrista brunsoni nov.sp.的特点是具有结节状的背侧/侧角质层、独特的颊管与咽管比例、第四腿爪上的锯齿状基部、第二腿和第三腿内爪基部的角质条、突出的管心针支撑物和两个薄的大花边，前半个长度是细长咽中第二个的长度。此外，还发现了一个单种的多毛菊属的标本。

Tardigrades of North America: Platicrista brunsoni nov. sp. (Parachela, Hypsibiidae, Itaquasconinae) from the Bob Marshall Wilderness Area of Montana

Abstract Eighty-three samples of moss and/or lichen were collected during a horse-packing trip into the southern half of Montana's Bob Marshall Wilderness Area in 2012. Tardigrades representing five families, ten genera, and eleven species were recovered from the samples. Two are new to Montana, and one is new to science. Raising the Montana tardigrade biodiversity to 23. The new species Platicrista brunsoni nov. sp. is distinguished by having a tubercated dorsal/lateral cuticle, a unique buccal tube to pharyngeal tube ratio, a serrated base on the claws of the fourth legs, a cuticular bar at the base of the inner claws on legs II and III, prominent stylet supports, and two thin macroplacoids, the first half the length of the second in the elongated pharynx. In addition, specimens of the monospecific genus Multipseudechiniscus were recovered.
