Remarks

• Structure: Adult female. Body spindle-form, up to 5 mm long, with posterior segments of abdomen heavily sclerotized. Antennae very short, each 2-segmented, about 50 μmlong. Legs entirely absent. Anal apparatus simplified, without setae; anal ring located inside of short anal tube; opening of anal tube at apex of abdomen. Vulva of unusual structure, funnel-shaped, opening directed anteriorly. Female ultimolarva (probably third immature instar). Body broadly oval, enlarged posteriorly, about 1.5 mm long. Antennae each 2-segmented, very short, about 40 μm long. Legs absent. Anal apparatus located on body surface (without anal tube) at apex of abdomen; structure of anal apparatus rather unusual, with anal opening covered by sclerotized operculum; anal ring with one row of very small poorly visible pores and with four minute setae. (Gavrilov-Zimin, 2017)
• Biology: The adult females and larvae inhabit individual conical domiciles on thin twigs of an undetermined species of bamboo (Poaceae). The domiciles are intensely black, each up to 7 mm wide and 8 mm high. In some cases the individual domiciles merge at their bases. Each domicile has a small orifice at the apex, which is used by the encapsulated insect for sprinkling the honeydew. The domicile consists of densely packed hyphae of sooty mould Capnodium sp. (Capnodiaceae) which are mixed with small portions of wax produced by the mealybug. (Gavrilov-Zimin, 2017)
