Drepanococcus chiton ( Green, 1909)

( Figs 4 , 5 )

Ceroplastodes chiton Green, 1909: 287 .

Diagnosis. Dorsum with preopercular pores present in front of anal plates, plus a few pores present on thorax ( Fig. 5C ). Venter with multilocular disc-pores frequently present on abdomen, not extending to metathorax ( Fig. 5E ); antenna 8 segmented, with 4th and 5th segments longer than wide ( Fig. 4C ).

Material examined. 2 ♀♀, LAOS, Paksong Dist., Champasak Prov., 9.ii.2016, coll. P.P. Soysouvanh, on Annona muricata L. ( Annonaceae ).

Hosts. Polyphagous. According to García Morales et al. (2016), D. chiton has been recorded from plants belonging to 20 genera in 14 families. In Laos, it has been recorded on Ficus sp. ( Moraceae ) ( Suh & Bombay 2015).

Distribution. Mainly known from Oriental Region ( India, Indonesia, Laos, Malaysia, Sri Lanka, Taiwan, Thailand and Vietnam) ( Ali 1971; Danzig & Konstantinova 1990; Suh & Bombay 2015).

Economic importance. Ibrahim (1994) noted that D. chiton is a potential pest of carambola ( Averrhoa carambola ), which is a commercial fruit mainly in South-East Asia, causing drying of shoots and flower stalks.

Remarks. Drepanococcus chiton is very similar to D. cajani (Maskell) . For a comparison, see the remarks section for D. cajani above.
