Genus Pulvinaria Targioni Tozzetti, 1866

Type species: Coccus vitis Linnaeus, 1758 , by original designation.

Diagnosis. Mature adult female with white ovisac visible under and posterior to body ( Fig. 43A ); dorsal tubular ducts present or absent ( Fig. 42E ); dorsal tubercles present or absent ( Figs 40B , 42D , 44D ); ventral tubular ducts of more than 2 types present in submarginal areas and/or medial areas of head, thorax and abdomen ( Figs 39D , 40J , 41D , 42J , 43D , 44I ); legs with tibio-tarsal articulatory scleroses ( Fig. 40I ) ( Hodgson 1994; Williams & Watson 1990; Choi & Lee 2017a).

Remarks. Pulvinaria is a large genus, consisting of 143 described species from all zoogeographical regions ( García Morales et al. 2016). Adult females of the genus are easily recognized by the presence of a white ovisac under and posterior to the body and several types of ventral tubular ducts present in the medial and submarginal areas of the body ( Hodgson 1994).
