Genus Pulvinaria Targioni Tozzetti

Pulvinaria Targioni Tozzetti, 1866: 146 .

Type species: Coccus vitis Linnaeus, 1758: 456 . By original designation and monotypy.

The new species, described below, is a typical member of the tribe Pulvinariini, of the subfamily Coccinae. The Pulvinariini is defined by the following combination of features: (i) production of a woolly ovisac; (ii) presence of ventral tubular ducts of 3 or 4 types (rarely 2), including a small duct with a fine inner ductule, which generally forms the submarginal band, and a larger duct with the inner and outer ductules of subequal width, which is typically present medially on head and thorax and occasionally elsewhere, (iii) absence of ovisac covering dorsum (or if mealy covering present, very sparse), (iv) absence of dorsal tubular ducts, or if present, of one type and typically similar to smallest of ventral tubular ducts, (v) presence of spinose dorsal setae, (vi) presence of a tibio-tarsal articulatory sclerosis, (vii) absence of pocket-like sclerotizations, (viii) presence of an eyespot near margin, and (ix) shallow, unsclerotized stigmatic clefts.

The present species keys out to the genus Pulvinaria in Hodgson´s keys to subfamilies, tribes and genera of Coccidae ( Hodgson, 1994) and fits into his Pulvinaria -group, in which tubular ducts are scarce or absent on the head. According to Hodgson (1994), this group can be further divided into those species that have distinctly bilocular pores on the dorsum ( Pendularia Fonseca and Tectopulvinaria Hempel ) and those without ( Chloropulvinaria Borchsenius , Neopulvinaria Hadzibejli and Pulvinaria ).
