Drepanococcus cajani (Maskell, 1891) 

( Figs 2 View Figure , 3 View Figure )

Eriochiton cajani Maskell, 1891a: 61  .

Diagnosis. Dorsum with preopercular pores restricted to abdomen ( Fig. 3D View Figure ). Venter with multilocular disc-pores frequent on abdomen, some groups also present laterad to metacoxa ( Fig. 3G View Figure ); antenna 7 or 8 segmented, with 4th and 5th segments each shorter than wide, or of similar length to width ( Fig. 2C View Figure ).

Material examined. 6 ♀♀, LAOS, Thaphabath Dist., Bolikhamsai Prov., 1.xi.2014, coll. J.Y. Choi, on Durio zibethinus  L. ( Malvaceae  ); 2 ♀♀, Viengkham Dist., Vientiane Prov., 28.iv.2015, coll. P.P. Soysouvanh, on Sanchezia speciosa Le.  ( Acanthaceae  ).

Hosts. Polyphagous. According to García Morales et al. (2016), D. cajani  has been recorded from plants belonging to 9 genera in 6 families.

Distribution. Oriental Region ( Hong Kong, India, Malaysia, Philippines, Sri Lanka and Taiwan) ( García Morales et al. 2016); Laos (new country record).

Economic importance. According to Shaw et al. (1999) and Sharma et al. (2015), D. cajani  is one of the more injurious pests of pigeon pea ( Cajanus cajan  ), which is a major crop in India.

Remarks. Drepanococcus cajani  is very closely related to D. chiton (Green)  . Williams & Watson (1990) and Hodgson (1994) gave the following morphological differences between the species (character states of D. chiton  in parenthesis): (i) 4th and 5th segments of antenna shorter than wide, or of similar length to width (longer than wide), (ii) multilocular disc-pores extending onto the metathorax (restricted to abdominal segments) and (iii) preopercular pores restricted to the abdominal segments (extending onto the thorax).
