Hi, Mark!

The first species appears to be Sinum javanicum, and maybe the second could be subadults or juveniles of that same species. Species 3 may be Cantharus cecillei, but the specimens from our area (Jeju Island, South Korea) are solid colored. I don't know about the fourth species, but No. 5 does appear to be Bursa lamarcki.

I hope this is helpful.

5 is definetely Bursa lamarki.

Best wishes,

Emma.

Hi,
Thank you for all help.
What do you think all Bursa are lamarckii?
