(1) Genealogies of sika deer and sika deer lice were estimated using partial sequence of mitochondrial COI gene. Three lineages were identified for sika deer(Continental, Northern and Southern clades) whereas two lineages were identified for deer lice(Continent+southern Kyushu and others);(2) analyses of topological congruence revealed that there is no significant pattern of codivergence between deer and lice. The present analyses only used the maternally inherited gene marker so that male-deer mediated lice dispersal is considered to be the main source of the incongruence ;(3) long distance dispersal of lice apart from their host is quite unlikely. In such case, louse population genetic tree can be good indicators of hidden population structure in their host ;(4) using morphometric analyses, microevolutionary changes in deer lice morphology is shown to accumulate along phylogenetic lines. The neutral characters appeared to comprise a larger fraction of the variation compared to those expected to be more functionally significant. This suggests that random drift of more neutral characters plays a major role in the microevolution of morphology of deer lice

（1）使用线粒体COI基因的部分序列估算了Sika Deer和Sika Deer虱子的家谱。鉴定出三个锡卡鹿（大陆，北部和南部进化枝）的谱系，而鹿虱（大陆+南部九州等人）的两个谱系被鉴定出来；（2）对拓扑的一致性分析表明，鹿和虱子之间没有显着的Codivergence模式。目前的分析仅使用了母体遗传的基因标记，因此男性介导的虱子分散被认为是不一致的主要来源；（3）除了宿主外，虱子的长距离分散是不可能的。在这种情况下，虱子种群遗传树可以是其宿主隐藏种群结构的良好指标；（4）使用形态计量学分析，鹿虱形态的微进化变化显示出沿系统发育线的积累。与预期在功能更重要的情况下相比，中性字符似乎占变异的较大部分。这表明，更中性字符的随机漂移在鹿虱形态的微观进化中起着重要作用
