雄性、雌性和雌雄同体的共存是一种罕见的交配系统，被称为三雄交配系统，被认为是进化上的短暂状态。在线虫中，在秀丽隐杆线虫中发现的雄二性体（雄性/两性体）被认为是从雌雄异株（雄性/雌性）通过雌雄异株中间体进化而来的。因此，雌雄异株的物种是很好的模型，以了解新的交配系统的进化的步骤和要求。本文描述了两种新的寄生三齿线虫，即Rhodensis金线线虫和A.l.弗赖堡。沿着分子条形码，我们提供了这些物种的形态学的详细分析，并与图纸和光和SEM显微照片文件。根据形态学数据，这些自由生活的线虫被分配到一个新的属，Auanema，连同其他三个物种先前描述。Auanema物种显示趋同进化的一些功能与寄生线虫具有复杂的生活史，如生产的少数男性异交后，dauers到自我繁殖的成年人的强制性发展。
The co-existence of males, females and hermaphrodites, a rare mating system known as trioecy, has been considered as an evolutionarily transient state. In nematodes, androdioecy (males/hermaphrodites) as found in Caenorhabditis elegans, is thought to have evolved from dioecy (males/females) through a trioecious intermediate. Thus, trioecious species are good models to understand the steps and requirements for the evolution of new mating systems. Here we describe two new species of nematodes with trioecy, Auanema rhodensis and A. freiburgensis. Along with molecular barcodes, we provide a detailed analysis of the morphology of these species, and document it with drawings and light and SEM micrographs. Based on morphological data, these free-living nematodes were assigned to a new genus, Auanema, together with three other species described previously. Auanema species display convergent evolution in some features with parasitic nematodes with complex life cycles, such as the production of few males after outcrossing and the obligatory development of dauers into self-propagating adults.
