Redescription

Female

Adult female in life covered with thick plates of white wax ( Fig. 3 ). Body broadly oval, about 9 mm long. Antennae 10-segmented, covered with flagellate setae of different thickness. Legs normally developed; trochanter with 3 sensillae on each face; claw without a denticle; claw digitules short, setose. Mouthparts well developed. Thoracic spiracles with spiracularia and groups of small quadrilocular pores, located in notch near each atrium. Abdominal spiracles numbering 7 pairs, located along abdominal margin on dorsum; each abdominal spiracle with unilocular atrium, without wax pores inside or just near spiracular atrium. Anal apparatus poorly visible in the available specimen, but it exactly represented by a short tube with internal sclerotized ring. Seven oval cicatrices present on venter posterior to vulva. Oval and round cuticular pouches of different size forming rows on dorsum and in marginal zone of venter (see Fig. 3 ). Wax glands represented by four types of discoidal pores: 1) large quadrilocular pores (each about 12 μm in diameter) with cuticular duct, scattered on dorsum and forming ovisac band on venter; 2) small quadrilocular pores (each about 9–10 μm in diameter) without cuticular ducts, scattered on venter; 3) trilocular pores (each about 9–10 μm in diameter) – probably modified small quadrilocular pores, occasionally present on dorsum and venter among normal quadrilocular pores; 4) multilocular pores (each about 12 μm in diameter), forming group around anal opening on dorsum and group around vaginal opening on venter. Large bitubular glands totally absent. Ovisac band present, formed by large quadrilocular pores. Conical setae very numerous, scattered on all dorsum and on ventral surface of cephalothorax; on dorsum more densely located conical setae additionally forming groups along margin, submargin and midline. Flagellate setae of different size and thickness numerous in medial and submedial zone of ventral cephalothorax and on abdominal sternites.

Primolarva

According to Morrison (1928: 151), the primolarva has 5-segmented antennae; short anal tube with double row of wax pores at inner end, with internal ring of disc pores and with circle of peculiar capitate setae around anal opening; single cicatrix present; quadrilocular pores, multilocular pores and large marginal bitubular glands present; dorsum covered with numerous conical setae.

Adult male and other larval instars

Unknown.

Remarks

The type specimens of the species from Sri Lanka and the specimens from India, studied by Morrison (1928: 148), have 3–5 cicatrices, whereas the female, studied by me shows 7 cicatrices.
