Remarks
- Systematics: Subfamily Cariococcinae (Choi & Lee, 2019) Drepanococcus chiton closely resembles D. cajani, but can be distinguished by several key characteristics. In D. chiton, the antennal segments are longer than wide, while in D. cajani they are nearly equal in length and width. Additionally, D. chiton has small, inconspicuous preopercular pores located near the anal plates and extending towards the thorax, whereas in D. cajani, these pores are larger, more prominent and extend to segment six. Furthermore, in D. chiton, multilocular pores are restricted to the abdomen, whereas in D. cajani, the pores are present on the metathorax. (Bhaskar et al. 2026)
- Structure: In life: Adult females covered by oval, convex test, which is granular or rough in texture, whitish to greyish and, completely opaque. Nymphs: elongate and yellow, covered with white wax granules. The mature female tests remain crowded in groups on the twigs along with male pupae, nymphs and younger females (Bhaskar et al. 2026). Dorsum with preopercular pores present in front of anal plates, plus a few pores present on thorax. Venter with multilocular disc-pores frequently present of abdomen, not extending to metathorax; antenna 8 segmented, with 4th and 5th segments longer than wide.
- Biology: Buckley & Gullan (1991) showed, in Papua New Guinea, that attendance by the aggressive ant, Oecophylla smaragdina (Fabricius), reduces the rate of parasitization. Reproduction is bisexual with a Lecanoid heterochromatinization in male embryos.(Gavrilov-Zimin, 2020)
- General Remarks: Good description and illustration of the adult female given by Tao et al. (1983), Tang (1991) and by Williams & Watson (1990). Photomicrographs by Bhaskar et al. (2026).
