Hi

Crossopalpus curvipes or Crossopalpus setiger? I cannot really decide which though it should be quite straight forward. There is no basal ad on t2 - that points to curvipes, but t3 has five strong bristles like setiger.
Chvála mentions in The Tachydromiinae of Fennoscandia and Denmark that curvipes sometimes (has) up to 4 and very exceptionally 5 (anterodorsals) in number (only seen in 2 females). Could this be one of those?

This female specimen was caught on April 19. 2011 in withered grass in birch forest near Copenhagen.

Regards,

I'd say that the antennal shape also more resembles that of C. curvipes.

Thanks! 3rd antennal segment is definitely about twice as long as broad.
A slightly aberrant Crossopalpus curvipes in other words. They were quite common in the grass. I'll see if I can catch some more representative individuals.
