Eusthenes Laporte, 1833  

Comments : Euthenes seems to me as one of the two most difficult genera of Tessartatomidae. A lot of species have been described, often with very short discussion, if at all, and it appears that is a great intraspecific variation. Yang has documented this variation for chinese Eusthenes in his paper about chinese Tessaratomidae (Yang We-I, 1935 - Notes on the Chinese Tessaratominae with description of an exotic species - Bulletin of Fan memorial institure of Biology, 6(3): 103-144, 5 pls)
No complete key of the genus exist, and even the partial ones are delusive. So the names given to the species of Eusthenes on this site should not be taken for granted, they are just temptative. To begin we will just display a couple of Eusthenes from China, at first identified as E. saevus Stål, but retrograded to E. sp. after comparison to the pictures of the type displayed on the site the Stockholm Museum
