Previous reports from the literature have indicated the northernmost range of extension of Ixodes minor Neumann to be southern Georgia with the greatest number of collections having been made in the coastal regions of that state. An unpublished record in the U.S. National Tick Collection indicated that I. minor had been collected as far north as South Island, Georgetown County, S.C., as early as 1933. I. minor was collected on three separate occasions in Charleston County, S.C., between October 1990 and February 1991, thus verifying the northern extension of this tick's range and the probable existence of a stable population on the coast of South Carolina. The roof rat (Rattus rattus) is reported for the first time serving as a host for I. minor.
文献中先前的报告指出，微小硬蜱（Ixodes minor Neumann）向北延伸的最远距离是佐治亚州南部，该州沿海地区的采集数量最多。美国国家蜱类收藏中的一份未发表记录表明，早在1933年，微小硬蜱就已在南卡罗来纳州乔治敦县的南岛采集到，向北延伸至此。1990年10月至1991年2月期间，在南卡罗来纳州查尔斯顿县三次分别采集到微小硬蜱，从而证实了这种蜱分布范围的向北扩展以及在南卡罗来纳州海岸可能存在稳定种群。首次报道屋顶鼠（Rattus rattus）作为微小硬蜱的宿主。
