Coordinator notes: Very close in appearance to coccinata but HW not red enough, even taking into account that is quite worn. Also, coccinata should have a thicker black median line thicker median black line. Another clue I use, which is not pointed out in any guides, is a thin dark line that surrounds the thorax, like an upside down U. Yours is hard to see, so look at other partas online and compare. Your second phot shows this better than the first. SG
