系统的基础硬蜱科之间的关系进行了研究，使用一个形态和三个分子数据集，18S和28S核和16S线粒体rDNA。虽然不同的分区组合在分区同质性检验中是不相容的，但将它们组合起来，通过加性和互补效应，对大多数主要谱系产生相似或更好的支持。不同的数据集是不完整的所有类群，但包括或排除类群与一个或多个数据集（29个内组类群中的8个）缺失的数据不影响整体树拓扑结构，只有微弱的影响支持水平。唯一显著的影响是基于28S数据集中的间隙处理。林隙处理完全改变了一个基节的排列和支持水平。综合分析表明，强有力的支持Metastriata，血统，包括最流行的澳大利亚硬蜱，和血统，包括其余的硬蜱，但不为Prostriata（=硬蜱s.l.）。澳大利亚特有类群的分布模式（几乎全部包括在三个专门的澳大利亚基底谱系）表明，这些谱系，并通过扩展的硬蜱科，起源于澳大利亚的隔离后，在白垩纪晚期，比以前指出的要近得多。(C)2000年，威利·亨尼希协会。
Systematic relationships among the basal Ixodidae are examined using one morphological and three molecular data sets, 18S and 28S nuclear and 16S mitochondrial rDNA. Although different combinations of partitions are incompatible in a partition homogeneity test, combining them produces similar or better support for most major lineages through both additive and complementary effects. The different data sets are not complete for all taxa, but inclusion or exclusion of taxa with missing data for one or more data sets (8 of 29 ingroup taxa) does not influence overall tree topology and only weakly affects support levels. The only notable effect was based on gap treatment in the 28S data set. Gap treatment completely changes the arrangement and support levels for one basal node. The combined analyses show strong support for the Metastriata, a lineage including most endemic Australian Ixodes, and a lineage including the remaining Ix-odes, but not for the Prostriata (= Ixodes s.l.). The distribution pattern of endemic Australian taxa (nearly all included in three exclusively Australian basal lineages) suggests that these lineages, and by extension the Ixodidae, originated after the isolation of Australia in the late Cretaceous, much more recently than previously indicated.
