Coccus capparidis (Green, 1904)

( Figs 16 , 17 )

Lecanium capparidis Green, 1904b: 187 .

Diagnosis. Dorsum with setae clavate ( Fig. 17C ); tubular ducts absent; duct tubercles present ( Fig. 17B ); and preopercular pores present anterior to anal plates ( Fig. 17D ). Marginal setae spinose, with pointed or slightly fimbriate apices ( Fig. 17J ). Venter with multilocular disc-pores each usually with 7 or 8 loculi, frequent around vulvar area, less frequently present on anterior area of abdomen ( Fig. 17F ); tubular ducts each with a narrow inner ductule, restricted to submarginal area of abdomen ( Fig. 17G ); pregenital setae numbering 1 or 2 pairs; antenna 6 or 7 segmented ( Fig. 17K ); and legs without tibio-tarsal articulatory scleroses ( Fig. 17H ) (partially adopted from Williams & Watson 1990; Wang & Feng 2012a).

Material examined. 2 ♀♀, LAOS, Saysetha Dist., Vientiane Capital, 24.vii.2016, coll. P.P. Soysouvanh, on Bauhinia malabarica Roxb. (Fabaceae) .

Hosts. Polyphagous. According to García Morales et al. (2016), C. capparidis has been recorded from plants belonging to 32 genera in 21 families.

Distribution. All zoogeographical regions; Oriental Region ( Hong Kong, India and Sri Lanka) ( García Morales et al. 2016); Laos (new country record).

Economic importance. Coccus capparidis has been listed as a potential pest of citrus in Egypt ( Morse et al. 1996); also, Ben-Dov (1980) and Blumberg & Swirski (1984) reported that in Israel it mostly infests citrus.

Remarks. Coccus capparidis differs from other Lao species of Coccus in possessing ventral tubular ducts in the submarginal areas of the abdomen only.
