The face is worn as the fly dried and the antenna is now inside the head. Very large and bright orange and well wisible anyway. There is no real label but just a date (?) 24.6.54. Any tips what this could be ? Some Rondania maybe ? Kaj can write more details himself. Jari JariF attached the following image: [134.81Kb] Edited by JariF on 10-03-2010 14:43

R, fasciata would be a good record from Finland although not revolutionary. I just wonder what seemed to be wrong because we didn\t unequivocally arrive to that conclusion with Tschorsnig and Herting...

Female of Rondania fasciata has lighter colouring and has "... Kopf weissgelb ... Hinterkopf und Peristom mit weissen Haaren, ... F�hler lebhaft orangegeld ... Thorax schwarz mit sehr dichter grauer Bereifung ..." (Mesnil in Lindner). Liekele

Member Location: Turku, Finland Posts: 208 Joined: 10.12.04	OK, now I believe that Rondania fasciata 1 f is the correct determination. The locality was the south-western archipelago, I think this is a locally good record, anyhow. Many thanks to all who participated in solving this old problem of mine. And special thanks to old Lindner, which I don't possess...
