Coccus viridis ( Green, 1889) 

( Figs 28View FIGURE 28, 29View FIGURE 29)

Lecanium viride Green, 1889: 248  .

Diagnosis. Dorsum with setae cylindrical, blunt apically ( Fig. 29AView FIGURE 29); tubular ducts absent; duct tubercles present ( Fig. 29FView FIGURE 29); and preopercular pores present anterior to anal plates ( Fig. 29EView FIGURE 29). Marginal setae short, mostly with fimbriate apices ( Figs 28CView FIGURE 28, 29IView FIGURE 29). Venter with multilocular disc-pores each usually with 7 loculi ( Fig. 29HView FIGURE 29); 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 28EView FIGURE 28, 29LView FIGURE 29); pregenital setae numbering 3 pairs; antenna 7 segmented ( Figs 28DView FIGURE 28, 29OView FIGURE 29); and legs each with a tibio-tarsal articulatory sclerosis ( Figs 28FView FIGURE 28, 29MView FIGURE 29) (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.
