Coccus viridis ( Green, 1889) 

( Figs 28 View Figure , 29 View Figure )

Lecanium viride Green, 1889: 248  .

Diagnosis. Dorsum with setae cylindrical, blunt apically ( Fig. 29A View Figure ); tubular ducts absent; duct tubercles present ( Fig. 29F View Figure ); and preopercular pores present anterior to anal plates ( Fig. 29E View Figure ). Marginal setae short, mostly with fimbriate apices ( Figs 28C View Figure , 29I View Figure ). Venter with multilocular disc-pores each usually with 7 loculi ( Fig. 29H View Figure ); tubular ducts each with a broad inner ductule, frequent in medial area between mesocoxae, between metacoxae, and occasionally a few present around each procoxa ( Figs 28E View Figure , 29L View Figure ); pregenital setae numbering 3 pairs; antenna 7 segmented ( Figs 28D View Figure , 29O View Figure ); and legs each with a tibio-tarsal articulatory sclerosis ( Figs 28F View Figure , 29M View Figure ) (partially adopted from Williams & Watson 1990).

Material examined. 5 ♀♀, LAOS, Pakxan Dist., Bolikhamsai Prov., 30.iv.2015, coll. J.Y. Choi, on Lagerstroemia  sp. ( Lythraceae  ); 17 ♀♀, Bolikhanh Dist., Bolikhamsai Prov., 4.v.2015, on Citrus sp. ( Rutaceae  ) (same collector); 2 ♀♀, Paksong Dist., Champasak Prov., 16.i.2017, coll. P.P. Soysouvanh, on Coffea  sp. ( Rubiaceae  ).

Hosts. Polyphagous. According to García Morales et al. (2016), C. viridis  has been recorded from plants belonging to 144 genera in 61 families. In Laos, it has been recorded on Ficus  sp. ( Moraceae  ) ( Suh & Bombay 2015).

Distribution. All zoogeographical regions; Oriental Region ( India, Indonesia, Laos, Malaysia, Myanmar, Philippines, Sri Lanka, Taiwan, Thailand and Vietnam) ( Suh & Bombay 2015; García Morales et al. 2016).

Economic importance. Williams & Watson (1990) recorded C. viridis  as an economically important pest of citrus and coffee in the tropical South Pacific; infestations have been reported also from Florida ( Fredrick 1943), Kenya and Papua New Guinea ( Murphy 1991).

Remarks. Among coffee pests in Laos, C. viridis  is similar to C. celatus De Lotto. For  a comparison, see the remarks section for C. celatus  above.
