Here is a extremely rare water spider from the genus Chresmoda with a short tail as a inexpensive example.
This variation of Chresmoda shows a clearly more short tailed Abdomen than the classical Chresmoda obscura from Solnhofen. It is might be a juvenile feature of Chresmoda obscura but is is obviously more rare than the normal specimens. Also the size of the most specimens is equal or larger them adult specimens of Chresmoda obscura. So this is might be a not jet described species of Chresmoda. It seems here is the need of research also on classical paleontological sites.
