Chalcopterus Beetle (True Darkling Beetle)

Today is my 7th anniversary on Project Noah, and this little beetle is helping to mark the occasion. It was trapped in a pot plant saucer, hence came out looking a bit dirty. It's known as a "true darkling beetle", from the family Tenebrionidae, and tribe Amarygmini. Beetles in this family are medium in size (this specimen about 12-15 mm), all black with an iridescent sheen. Their antennas are medium length, body is stout, and their legs are relatively long. One distinct feature of the genus is the head which is held vertically against the body. I think this gives them a nice streamline effect.
