Coprolactistus whitakeri Radovsky & Krantz, a new genus and species of Macronyssidae, is described in all stases. Unlike other macronyssids, all of which are vertebrate parasites, C. whitakeri is predaceous, feeding on other mites in bat guano. Its morphology confirms the family assignment, and it has the peculiar macronyssid life cycle in which a regressive, nonfeeding deutonymph follows a normal, feeding protonymph. The chelicerae are typically macronyssid despite the predatory diet. Available information indicates that C. whitakeri evolved from macronyssid parasites. C. whitakeri is a distinctive species that is not obviously close to any other described macronyssid. It occurs in the guano of the big brown bat, Eptesicus fuscus, in Indiana and in the guano of an unidentified bat in Brazil.
描述了巨刺螨科的一个新属新种——惠特克氏粪刺螨（Coprolactistus whitakeri Radovsky & Krantz）的各个虫态。与其他所有巨刺螨不同，其他巨刺螨均为脊椎动物寄生虫，而惠特克氏粪刺螨是肉食性的，以蝙蝠粪便中的其他螨虫为食。其形态学特征确定了它所属的科，并且它具有独特的巨刺螨生命周期，即一个退化的、不进食的若螨期紧随一个正常进食的幼螨期。尽管其为肉食性，但螯肢仍具有典型的巨刺螨特征。现有信息表明，惠特克氏粪刺螨是从巨刺螨寄生虫进化而来的。惠特克氏粪刺螨是一个独特的物种，与其他已描述的巨刺螨没有明显的亲缘关系。它存在于印第安纳州大棕蝠（Eptesicus fuscus）的粪便中，以及巴西一种未鉴定蝙蝠的粪便中。
