My first guess, based on the generally shiny black body colour and the white dusted postpronotal lobes with 2 bristles, was Leiophora innoxia.

I have tried to key it through but there are some important areas that are not clear - such "how far back is the excavation in T1+2?" and "are the apical scutellar bristles crossed near their midpoint - or not crossed/only crossed at their tips?". Also, clarifying the colour of tha palps would be useful. :)
