Coccus gymnospori ( Green, 1908) 

( Figs 22View FIGURE 22, 23View FIGURE 23)

Lecanium gymnospori Green, 1908: 29  .

Diagnosis. Dorsum with setae cylindrical, blunt apically ( Fig. 23DView FIGURE 23); tubular ducts sparsely present in submarginal areas ( Fig. 23CView FIGURE 23); duct tubercles present ( Fig. 23AView FIGURE 23); and preopercular pores present anterior to anal plates ( Fig. 23EView FIGURE 23). Marginal setae spinose, with pointed or slightly fimbriate apices ( Fig. 23MView FIGURE 23). Venter with multilocular discpores each usually with 8–10 loculi ( Fig. 23GView FIGURE 23); tubular ducts each with a narrow inner ductule, a few present between mesocoxae, and around meta-, meso-, and procoxa ( Figs 22DView FIGURE 22, 23LView FIGURE 23); pregenital setae numbering 3 pairs; antenna 8 segmented ( Figs 22CView FIGURE 22); and legs each with a tibio-tarsal articulatory sclerosis ( Figs 22EView FIGURE 22, 23IView FIGURE 23) (partially adopted from Ben-Dov 1981; Avasthi & Shafee 1991).

Material examined. 3 ♀♀, LAOS, Salakham-nua Village, Hadxayfong Dist., Vientiane Capital, 30.iv.2015, coll. J.Y. Choi, on Mangifera indica  L. ( Anacardiaceae  ); 5 ♀♀, Phou Khao Khuay National Bio-Diversity Conservation Area, Thaphabath Dist., Bolikhamsai Prov., 4.v.2015, on Dalbergia cochinchinensis Pierre ex Laness.  ( Fabaceae  ) (same collector).

Hosts. Gymnosporia montana  ( Celastraceae  ) ( Avasthi & Shafee, 1991).

Distribution. Oriental Region ( India and Sri Lanka) ( Avasthi & Shafee, 1991); Laos (new country record).

Economic importance. Coccus gymnospori  has not yet been recorded as an economically important pest.

Remarks. Coccus gymnospori  is related to C. elatensis Ben-Dov  , C. hesperidum Linnaeus  and C. moestus De Lotto. Ben-Dov (1981)  differentiated C. gymnospori  from the other species using the following combination of characters: (i) the presence of 3 pairs of pregenital setae, (ii) antenna 8 segmented, (iii) dorsal tubular ducts shorter than or equal to length of ventral tubular ducts, and (iv) preopercular pores numbering 6–22 in a group.
