3.5mm, Clitheroe UK, 31 May 2011.
I keyed this to
Hercostomus assimilis in Fonseca. Did I get close?

Thanks Igor! I just went wrong at the last couplet. To me the face seems dusted brownish white, but it does have black patches below the antennae. (The cerci are dark, but under strong light they are definitely yellow.)
