Researchers are adding three more to the 4,500 species of cockroaches known to science, according to LiveScience.

Though they fall into the giant cockroach family (Blaberidae) these newly found, yellow-bodied creatures are small compared with some of their cousins — they grow just a little more than an inch (3 centimeters) in length in adulthood, compared with Blaberus giganteus, for example, which can reach lengths of 4 inches (10 cm).

The recently discovered insects are the first of the genus Pseudophoraspism to be found in China, researchers say. Until now, cockroaches of that genus had only been documented in Southeast Asia, never north of Vietnam.
