FIGURE 5. Drepanococcus chiton (Green, 1909) , adult female, from Williams & Watson (1990). A, dorsal microduct; B, simple pore; C, preopercular pores; D, anal plates; E. multilocular disc-pore; F. anterior and lateral marginal setae on anogenital fold; G, ventral tubular duct; H, spiracular disc-pore; I, stigmatic spine (broken) and marginal setae; J, ventral microduct. Diagnosis. Mature adult females hemispherical, with a sclerotised caudal process, entirely covered with a thick wax; wax test with distinct shape and color ( Figs 6A , 8A , 10A , 12A , 14A ); dorsal derm with clear areas lacking either pores or setae ( Figs 7 , 9 , 11 , 13 , 15 ); characteristic stigmatic spines numerous, arranged in and beside stigmatic clefts or on margin ( Figs 6C , 7C , 8C , 9B , 10D , 11K , 12C , 13A , 14D , 15B ) ( Gill 1988 ; Hodgson 1994 ; Hodgson & Peronti 2012 ). Remarks. Ceroplastes is a large genus, comprising about 144 described species from all zoogeographical regions ( García Morales et al. 2016 ). In the field, members of the genus are easily recognized by the thick wax test on the dorsum of the adult female. Adult female Ceroplastes differ from all other Lao Coccidae species in possessing characteristic stigmatic spines ( Hodgson & Peronti 2012 ).
