- General Remarks: Detailed description and illustration in Takagi, 2008.
- Biology: The known species occur on the lower surface of the leaves, females usually on the lateral sides of the midrib and other veins. The male tests are detached from the leaf surface except for the anterior end, with the ventral as well as the dorsal portion formed well. They are white, elongate, parallel-sided, and flat dorsally. (Takagi, 2008)
- Systematics: These species are mainly recognized on the basis of their second instar females. The adult females are very simplified in external structure, the second-instar males are uniform.
- Structure: Annonogena is a pupillarial genus, the adult female being entirely enclosed within the second-instar exuvial cast, which is strongly sclerotized and may appear like a minute plant seed. Body elongate ellitical, rounded on both ends, membranous, with segmentation obscrue except on ventral surface of prepygidial abdomen, pygidium appearing to comprise fourth or fifth and succeeding segments.
The male constructs a good test. The first instar exuvial cast of the male is elliptical and bivalve, the dorsal and ventral surfaces separated from each other. (Takagi, 2008)
