本文报道了越南北方发现的空口虫属（Coelostoma）（Lachnocoelostoma）thienemanni Orchymont，1932（鞘翅目：水螅科：球壳虫亚科：空口虫族），这是自1929年以来该虫在亚洲大陆的首次记录。该种被重新描述和图解，并从Holocoelostoma Mouchamps，1958亚属转移到Lachnocoelostoma Mouchamps，1958。该种在亚洲腔口吸虫属中是不寻常的，因为它具有复杂的三维形状的aedeagus中叶，其中它仅类似于C。tangliangi Jia等人，2017年在亚洲。该物种也不寻常的是其非常长的背跗游泳毛，表明它是一个水生物种。
We are reporting a recent discovery of Coelostoma (Lachnocoelostoma) thienemanni Orchymont, 1932 (Coleoptera: Hydrophilidae: Sphaeridiinae: Coelostomatini) from northern Vietnam, which represents the first record of the species since 1929 and its first record from continental Asia. The species is redescribed and illustrated, and transferred from the subgenus Holocoelostoma Mouchamps, 1958 to Lachnocoelostoma Mouchamps, 1958. The species is unusual among Asian Coelostoma by its complex three-dimensional shape of the median lobe of the aedeagus, in which it is only similar to C. tangliangi Jia et al., 2017 in Asia. The species is also unusual by its very long dorsal tarsal swimming hairs, indicating that it is an aquatic species.
