>>Terry, Thanks for your input. The "yellow patternless" i spoke of is in my 3rd post (3 pics) on the thread. Looks a lot like E.o. quadrivittata. It is as different to the others as schrenki is to anomala (pertaining to color/pattern). It is just as common as anomala (so i am told) but i am not certain of the ranges of either and wether their ranges overlap. This is all information that i need to try to gather and i have several sources but i suspect that much of it will have to be done with field work. As far as ranges go I can probably get a lot of data by simply taking some pictures of each species / color variation and jumping in the car and driving the peninsula, stopping at old timer farms and asking which ones they are familiar with seeing in that area. >>
Don, I happened to see a couple anomala from China posted in the photo section of Schulz' book ('96). One is mostly gray and one mostly yellowish and they are mostly w/o pattern, except in the posterior. I think the unicolor pattern of anomala might be fairly common and in a number of different locations. I also saw a brown form of E. s. schrencki from Russia.
>>You know, it is rather ironic because i travel all over and always hoped to find a new species in my travels. Considering the few number of species here compared to the locations i travel too, there is still a lot of information lacking and even if i never find a yet undescribed species, there is still plenty of work that i can do right here. And i even get to sleep in my own bed. >> >>Anyway, the island i visited 2 years ago is much more distant and remote than the one i visited last year. We had to coordinate a korean navy boat to take use there and was actually going there last year but the navy boat that was laid on did not have a transfer boat and so there was no way to get us to shore so we opted for a closer island that we could get close to for a transfer. Hopefully this coming year. We will have to see. >> >>Thanks again for the info. I will post any new findings to the forum.
>>Don
I look forward to any new findings you make. I think the Korean Peninsula is a great place to do studies and possibly make new discoveries. I might even make a trip there myself someday.
That far away island you found the hyper melanistic schrencki on sounds very intriguing. I have thought of a possible scenario and how that could be schrencki and not anomala. Suppose that during the ice ages the cold drove schrencki farther south and onto this island, anomala being even further south. After the ice age is over and the warmth comes back, anomala returns north to it's former range, but the schrencki on this remote island gets stranded and can't return north. Because this island is windy and colder than the mainland, schrencki is able to survive this far south. It could be a relict population. Anyway, just something to be hopeful about.
I will try to put a link to a Russian website that has many dione variations you can check out. Let's see if this works... www.edione.narod.ru/ It also has some links to other sites.
