Dropephylla ioptera

I found this indoors. Getting it to the correct genus took a couple of goes but once there the species was easy. The length of the beetle was around 2.4mm. I was initially concerned when I googled pictures of this species as most showed paler redder pronotum that my photo shows. But there's a bit of variation - some are darker, anad also my dead specimen has strongly contrasting paler red pronotum (and basal segments to the abdomen), much more so than the photo of the live insect shows.
