Lundblad (1936) had reported this species from Northwest China, while the previous descriptions were relatively simple (Uchida &amp; Imamura 1951). Current specimens, which were also collected from Northwest China (Qinghaihu National Nature Reserve), are similar with the description mentioned above, especially their eye plate, which is considered as the most distinguishing feature. The only difference with the Turkish population is the body size: males ranging from 1859 to 2539, females ranging from 1725 to 1824 in our specimens, but with the Turkish population, 2250 for the male and 4200 for the female (Sezek &amp; Özkan 2000). This problem can be interpreted by Lanciani (1969, 1970) that the size of newly emerged eylaid mites could increase continuously in both sexes, even during their adult stages, and the gravid females could grow twice as long. In summary, we attribute our specimens to E. (M.) hamata.</p> </div>	http://treatment.plazi.org/id/03C01C5FB140FFB64716BC3B539BFA82	Public Domain	No known copyright restrictions apply.

This larval-based taxonomy results in a parallel system in Limnocharidae, for which taxa have previously been based on adults. On the other hand, Gerecke et al.

To avoid confusion in the taxonomy, four larval-based genera (Veliacola, Archaeveliacola, Armaveliacola, Isoveliacola) and genus Neolimnochares are not listed in this adult-charactered binomial key.</p> </div>	http://treatment.plazi.org/id/03C01C5FB14AFFBD4737BFF0504FF92F	Public Domain	No known copyright restrictions apply.
