在中国东北内蒙古和辽宁的四个中侏罗世化石地点描述的水生coptoclavid甲虫（鞘翅目：Adephaga：Dytiscoidea）的成年人被归因于Daohugounectes primitive Wang，Ponomarenko和Zhang，2009，这是之前在研究幼虫后提出的。属名Timarchopsis Brauer，Redtenbacher and Ganglbauer，1889被提议作为替代，以替代被占据的和初级的同名词Necronectes Ponomarenko，1977，非Milne‐Edwards，1881。此外，亚科名称Necronectinae Ponomarenko，1977被可用名称Timarchopsinae取代。Daohugounectes被归入Timarchopsinae，因为它的成年人有长的，稍微顶部加宽的胫骨和小的股骨板。本属成虫与其他Timarchopsinae的不同之处在于以下特征：触角短，中部加宽;原跗基节顶部不切;后腹面具三角形板。幼虫看起来有点像Timarchopsinae亚科的原始形式。与这些原始幼虫相比，具有一些先进特征的成虫可以被认为是Timarchopsinae亚科中最先进的形式之一，并且可能代表Timarchopsinae和Charanoscaphinae之间的过渡。这种镶嵌式的进化表明水生甲虫的进化过程比以前想象的要复杂得多。
Adults of the aquatic coptoclavid beetles (Coleoptera: Adephaga: Dytiscoidea), described from four Middle Jurassic fossil localities in Inner Mongolia and Liaoning in northeastern China, are attributed to Daohugounectes primitives Wang, Ponomarenko and Zhang, 2009, which was previously proposed after study of larvae. The generic name Timarchopsis Brauer, Redtenbacher and Ganglbauer, 1889 is proposed as a substitute for the preoccupied and junior homonym Necronectes Ponomarenko, 1977, non Milne‐Edwards, 1881. Furthermore, the subfamily name Necronectinae Ponomarenko, 1977 is substituted by the available name Timarchopsinae. Daohugounectes is placed into Timarchopsinae because its adults have long, slightly apically widened tibiae and small femoral plates. The adults of this genus differ from those of other Timarchopsinae in the following features: antennae short and widened in the middle part; basal segments of protarsi not cut apically; metaventrite with a triangular plate. The larvae look like somewhat primitive forms in the subfamily Timarchopsinae. In contrast to these primitive larvae, the adults with some advanced characters can be regarded as among the most advanced forms in the subfamily Timarchopsinae, and probably represent a transition between the Timarchopsinae and Charanoscaphinae. Such mosaic evolution within Daohugounectes indicates that the evolutionary process of aquatic beetles is far more complex than previously thought.
