Remarks

• Systematics: Thysanococcus madecassus differs from all known members of the genus by the occurrence of a regular series of 3 different types of quinquelocular pores in the submarginal area of the dorsum of the 2nd stage female (Mamet, 1959a).
• Structure: The second stage female completely encloses the adult female and is well-sclerotized dorsally, weakly sclerotized ventrally, light brown, fairly convex, widest across the anterior half, tapering towards the posterior extremity, coated with a thin layer of colorless glassy secretion, with short fine and pale-brown thread-like secretions arising from the margin of the body. Adult female oval, pygidium not demarked from the remainder of body. Derm membranous throughout, except for the weakly-sclerotized dorsal surface of pygidium. Slide-mounted specimen about 0.4 mm long. Pygidium longer than broad, rounded apically; dorsal area weakly sclerotized, oval, with anal orifice very small, without setae and situated at about its apical third (Mamet, 1959a).
• General Remarks: Mamet (1959a) describes and illustrates the adult and second-instar female.
