(Figs 22, 23)

Lecanium gymnospori Green, 1908: 29 .

Diagnosis. Dorsum with setae cylindrical, blunt apically (Fig. 23D); tubular ducts sparsely present in submarginal areas (Fig. 23C); duct tubercles present (Fig. 23A); and preopercular pores present anterior to anal plates (Fig. 23E). Marginal setae spinose, with pointed or slightly fimbriate apices (Fig. 23M). Venter with multilocular discpores each usually with 8–10 loculi (Fig. 23G); tubular ducts each with a narrow inner ductule, a few present between mesocoxae, and around meta-, meso-, and procoxa (Figs 22D, 23L); pregenital setae numbering 3 pairs; antenna 8 segmented (Figs 22C); and legs each with a tibio-tarsal articulatory sclerosis (Figs 22E, 23I) (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.
