The Asian cockroach (Blattella asahinai), is a species of cockroach that was first described in 1981 from insects collected on Okinawa Island, Japan. It is a small species of cockroach, typically 1.3 to 1.6 centimetres (1⁄2 to 5⁄8 in) long and tan to dark brown in colour with dark parallel stripes on the back of their heads. It is commonly mistaken with the German cockroach (B. germanica) for their similar appearance. It is commonly found in the United States in and around houses. From Wikipedia
