(i) The common name of Periplanata americana is the American cockroach.

(ii) Four pairs of spermathecae are present between sixth and the ninth segments. They help in receiving and storing the spermatozoa during copulation.

(iii) The female reproductive system of cockroach consists of two large ovaries. The ovaries lie laterally in the 12th and 13th segments. Each ovary is formed of a group of eight ovarian tubules or ovarioles. They contain a chain of developing ova. Oviducts from each ovary unite into a single median oviduct.

(iv) The abdomen consists of 10 segments. In females, the 7th segment is boat shaped. The 7th sternum; together with the 8th and 9th sterna; forms a brood or genital part. In both sexes, the 10th segment bears of pair of jointed filamentous structures called anal cerci.

(v) The Malpighian tubule system is a type of excretory and osmoregulatory system found in some insects, myriapods, arachnids, and tardigrades. The system consists of branching tubules extending from the alimentary canal that absorbs solutes, water, and wastes from the surrounding hemolymph. These tubules are found in cockroaches.
