Pulvinaria floccifera ( Westwood, 1870) 

( Figs 39 View Figure , 40 View Figure )

Coccus flocciferus Westwood, 1870: 308  .

Diagnosis. Dorsal derm without polygonal reticulations; tubular ducts absent; duct tubercles present ( Fig. 40B View Figure ). Marginal setae with pointed or frayed apices ( Fig. 40D View Figure ). Stigmatic clefts distinct, each containing 3 stigmatic spines ( Figs 39C View Figure , 40E View Figure ). Venter with multilocular disc-pores usually each with 7 loculi, mainly present around vulvar area, a few pores also present laterad of each meta-, meso- and procoxa ( Fig. 40H View Figure ); tubular ducts of 3 types: type I each with a broad inner ductule, mainly present on medial area of head, thorax and anterior abdomen, type II each with a narrow inner ductule, mainly present on medial area of posterior abdomen and submarginal area of abdomen, and type III each with a filamentous inner ductule, present on submarginal area ( Figs 39D View Figure , 40J View Figure ); antenna 6 to 8 segmented ( Fig. 40M View Figure ) (partially adopted from Tanaka & Amano 2007).

Material examined. 2 ♀♀, LAOS, Pakngum Dist., Vientiane Capital, 28.viii.2016, coll. P.P. Soysouvanh, on Centotheca lappacea  (L.) Desv. ( Poaceae  ).

Hosts. Polyphagous. According to García Morales et al. (2016), P. floccifera  has been recorded from plants belonging to 50 genera in 35 families.

Distribution. All zoogeographical regions; Oriental Region ( India and Vietnam) ( Hodgson & Henderson 2000; García Morales et al. 2016); Laos (new country record).

Economic importance. Łagowska et al. (2017) described P. floccifera  as a serious pest of ornamental plants in Europe; and in Iran, it is considered to be a serious pest of citrus ( Naeimamini et al. 2014) and tea ( Camellia sinensis  ) ( Hallaji-Sani et al. 2012).

Remarks. Pulvinaria floccifera  is very similar to P. urbicola Cockerell  , but Tanaka & Amano (2007) separated the species based on the presence or absence of dermal areolations and the number of preopercular pores: P. floccifera  lacks dermal areolations and has 48–83 preopercular pores, whereas P. urbicola  has dermal areolations and only 4–27 preopercular pores.
