Supella dominicana (IMAGE) Oregon State University Caption George Poinar Jr., professor emeritus in the OSU College of Science, has identified a new cockroach species. The male specimen, which Poinar named Supella dominicana, is encased in Dominican amber and is the first fossil cockroach to be found with sperm cells. “It is well preserved with a yellow cross bar across the wings and a central, vertical, yellow stripe that appears to divide the body into two parts,” he said. “It has long spines, used for defense, on its legs, especially the hind legs. Also of interest is the sperm bundle containing spermatozoa with dark acrosomes, structures covering the head of the sperm, since fossil sperm are rare.” Credit George Poinar Jr. Usage Restrictions None License Original content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
