I think the head shape does not fit Paralaea (genus). Looks very similar to T. ptochodes. See here: https://bie.ala.org.au/species/https://biodiversity.org.au/afd/taxa/f450fb2b-43cb-4161-ac6c-b2ee90a84096
Several Tachystola species have a dark submarginal band which could have been eroded in this worn specimen to a residual spot in the middle of that band.
