Molecular and morphological evolution on free-living nematodes

从美洲中部、东亚、东南亚和非洲的热带和亚热带地区采集了无花果线虫和昆虫(主要是甲虫和黄蜂)。在形态观察和分子系统发育分析的基础上，进行了几个新种的描述和重新描述。在此基础上，结合分子系统发育关系对双胃线虫的形态特征进行了比较，并对其气孔形态的演化史进行了考察。

Diplogastrid nematodes were collected from Ficus syconia and insects(mostly beetles and wasps) from tropical and subtropical regions in Middle America, East Asia, South-East Asia and Africa. Based upon the morphological observations and molecular phylogenetic analyses, several new species descriptions and redescriptions were conducted. Further, the morphological characters were compared with molecular phylogenetic relationship, and the evolutionary history of stomatal morphologies was examined for diplogastrid nematodes.
