An Anthribidologist friend of mine sent me this picture of a specimen from Thailand. The specimen was mistakenly sent to him as an Anthribid (prothorax's deep depression apparently similar to the anthribid genus Stiboderes). Any idea what it is?
Yes, it closely matches P. parvus. I have a photo of a lectotype, but the lectotype has a little less reddish-brown pubescence on the apex of the elytra. The specimen from Thailand has more distinct sculpturing on the pronotum, however the photographs are not conclusive. Without a series of specimens, it is impossible to see if there is variation in this species.
