Astylopsis macula (Lamiinae)

Found a bunch of these flat-faced longhorn beetles on a dying tree a few weeks ago. I’m fairly confident it’s Astylopsis macula. But there are a gazillion genera of Lamiinae, so I’m happy to be corrected. Would also be very happy to hear from anyone who knows what elytral pits do, other than providing handy identification. I’ve wondered about that for years. Are they vestigial patterns from forewing ancestry? Sound-dampening trick to elude echolocating bats? Are pits just decorations, useful in crypsis or for intraspecific recognition? If you know, would love to hear from you.
