Coccus formicarii ( Green, 1896)  

( Figs 20 View FIGURE 20 , 21 View FIGURE 21 )

Lecanium formicarii Green, 1896: 10   .

Diagnosis. Dorsum with setae sharply setose ( Fig. 21C View FIGURE 21 ); tubular ducts and duct tubercles absent; preopercular pores present in an elongate group anterior to anal plates ( Fig. 21D View FIGURE 21 ). Marginal setae spinose, with pointed apices ( Figs 20C View FIGURE 20 , 21B View FIGURE 21 ). Venter with multilocular disc-pores each usually with 7–10 loculi ( Fig. 21G View FIGURE 21 ); tubular ducts each with a narrow inner ductule, abundant on medial area between procoxae, between mesocoxae, and around each meso- and metacoxa ( Figs 20D View FIGURE 20 , 21I View FIGURE 21 ); pregenital setae numbering 3 pairs; antenna 7 or 8 segmented ( Fig. 21L View FIGURE 21 ); and legs without tibio-tarsal articulatory scleroses ( Figs 20E View FIGURE 20 , 21H View FIGURE 21 ) (partially adopted from Hodgson 1994).

Material examined. 25 ♀♀, LAOS, Phou Khao Khuay National Bio-Diversity Conservation Area,  

Thaphabath Dist., Bolikhamsai Prov., 4.v.2015, coll. J.Y. Choi, on Ficus benghalensis   L. ( Moraceae   ).

Hosts. Polyphagous. According to García Morales et al. (2016), C. formicarii   has been recorded from plants belonging to 44 genera in 30 families.

Distribution. Mainly known from Madagascan and Oriental Regions ( India, Indonesia, Malaysia, Sri Lanka, Taiwan and Thailand) ( García Morales et al. 2016); Laos (new country record).

Economic importance. Evans & Dooley (2013) recorded C. formicarii   as a frequently intercepted species at U.S. ports and a potential threat to the U.S.A.; however, heavy infestations on its hosts have not yet been reported.

Remarks. Coccus formicarii   is most similar to C. multisetus Wang & Feng   , but differs from it in having 3 pairs of pregenital setae and in lacking ventral tubular ducts in submarginal areas. In contrast, C. multisetus   has only 2 pairs of pregenital setae and ventral tubular ducts sparsely present in submarginal areas ( Wang & Feng 2012a).
