Collected at lighted sheet. Keyed using (1), pg 13. This is
definitely not S. costatus, as the carinae are different. According to the
key, the interspaces are impunctate and have 2 very fine, flat carinae instead
of the punctation seen on S. dentiger. Hope the 2 carina are visible in the
photo and maybe Mike Thomas can chime in. If correct, would need a guide page.
I also think this is the same species Jamie Garrison submitted a short while
back under .
