Among several unusual species collected during surveillance of ectoparasites on wildlife hosts in the southeastern United States and Caribbean Region, the larvae of a new species of Whartonacarus were encountered in 2003 on a cattle egret, Bubulcus ibis (L.), in the Florida Keys. This is the first record for a member of Whartonacarus in the continental United States. The mite is described and named as Whartonacarus floridensis Mertins, and the possible significance of this discovery with respect to the "tropical bont tick," Amblyomma variegatum (F.), is discussed. A brief taxonomic review of Whartonacarus raises questions about the putative synonymy of Whartonacarus nativitatis (Hoffmann) and Whartonacarus thompsoni (Brennan) and suggests that Whartonacarus shiraii (Sasa et al.) may include two distinct taxa. Whartonacarus is redefined, and a revised key to the known taxa is provided. Toritrombicula oceanica Brennan & Amerson is placed in the genus Whartonacarus. Also, Whartonacarus palenquensis (Hoffman) is rejected as a member of this genus and placed in its own new genus, Longisetacarus Mertins.
在对美国东南部和加勒比地区野生动物宿主的外寄生虫进行监测期间，收集到了几种不寻常的物种，其中包括 2003 年在佛罗里达群岛的一只牛背鹭（Bubulcus ibis（L.））上发现的一种新的华通螨幼虫。这是在美国大陆首次记录到华通螨属的成员。这种螨虫被描述并命名为佛罗里达华通螨（Whartonacarus floridensis Mertins），并讨论了这一发现与“热带邦特蜱”（Amblyomma variegatum（F.））的可能意义。对华通螨属的简要分类审查提出了关于假定的华通螨属（Whartonacarus nativitatis（Hoffmann）和华通螨属（Whartonacarus thompsoni（Brennan））的同义词以及华通螨属（Whartonacarus shiraii（Sasa et al.））可能包含两个不同分类群的问题。对华通螨属进行了重新定义，并提供了已知分类群的修订关键。Toritrombicula oceanica Brennan & Amerson 被归入华通螨属。此外，华通螨属（Whartonacarus palenquensis（Hoffman））被拒绝作为该属的成员，并被置于自己的新属，长须螨属（Longisetacarus Mertins）中。
