Could this be Thelaira nigripes? I think it keys to Thelaira OK (hairy antennae, very slight facial ridge, no petiole, narrow gena, vein 1 hairy), but there is only one long antero-dorsal bristle on one of the mid-tibiae (and that is broken indicating a good deal of damage) and I can't see the scar of where another would have been. Are there any other suggestions? By the way there is a distinct narrow bar of dense black between the post sutural acrostichals - could this be an identification feature?

Yes, that looks fine  Colouration on Thelaira is a very unreliable feature and I have never been all that convinced by people that say that the dusting provides any more certainty - especially on older specimens
