I'v just found out why Schulz didn't list E frenata. They were first found or should I say identified in 1998 they might have been found and mistaken for Cyclophiops major. They are very rare - 3 or 4 end up being found each year. They are exactly the same as the ones found in China. This and their recent discovery is driving a debate if they have been here all along or if, they some how found their way here from China, in the recent past.
