    Please convey my thanks to Adam! This is the first image for ALA and also the first WA record. Interestingly, there isn't any bracket fungi anywhere; they were found in a dead Sesbania log.

    About 1.5cm long, found in dead wood. Individuals both with and without horns were found in the same tunnels, so this trait may be sexual dimorphism. The horned individuals had an orange organ at the tip on their horns and pointing inward that superficially resembles that of the north American Bolitotherus; except that Bolitotherus's horns are on the thorax, not the head. Not sure if it could be a Zopheridae or Tenebrionidae.
