We examined 13 adult females identified as C. pilosellae that were collected in “ Czechoslovakia,” France, Hungary, Poland and Slovakia. We also have examined a slide with an adult female intercepted at New York from England on Gentiana andrewsii collected May 12, 1936, by Lennox but, because this species has never been collected in the UK, the locality data are suspect. In this species, the eyes are about the same height as the length of first antennal segment. We have examined specimens with 8- and 9-segmented antennae. The intersegmental sensilla are variable and often obscure and difficult to see. It appears that they are variably present between segments III– IV, IV–V and VI–VII. One specimen appears to have sensilla between the above mentioned segments as well as V– VI and VIII–IX. The legs are shorter than those in Puto and possess fewer setae; campaniform sensilla on the trochanters always number two on each surface; the claws are thick and short and lack basal spurs, and the digitules are clubbed. Tubular ducts are present on the frons. Trilocular pores on the venter are smaller than those on the dorsum, and pores in the cerarii are only slightly larger than those on the rest of the dorsum.

First-instar nymphs collected in Hungary (Budapest, Sashegy, 18.x.1996, in caricetum habitat by B. Kiss) and examined by Ferenc Kozár, and embryos collected in Turkey (Hakkari-Beyköy, on Euphorbia sequeriana (Euphorbiaceae) , 1832 m) and examined by M. Bora Kaydan, all possess 6 antennal segments. We agree with Hardy et al. (2008) that this species should be retained in the genus Ceroputo in the family Pseudococcidae . This species has a wide distribution in the Palaearctic Region ( Ben-Dov & Kaydan, 2008).

Kanda (1959) described Leococcus erigeroneus , collected from Erigeron canadensis (Asteraceae) in Japan, as the type species of his genus Leococcus . Kawai (1980) transferred the species to Puto , thus treating Leococcus as a junior synonym of Puto . Danzig (1980) suggested that L. erigeroneus was probably a synonym of P. pilosellae but did not formally list it as such. Tang (1992) appears to have been the first to formally cite L. erigeroneus as a junior synonym of C. pilosellae . We have studied the description and illustration given by Kanda (1959) and we conclude that the species is identical to C. pilosellae .

Takahashi (1932) described Phenacoccus asteri for specimens collected on Aster lauruleanus (Asteraceae) in Taiwan. It was transferred to Puto by Tang (1992), but the original combination was revived by Ben-Dov (1994).

We have examined the original illustration and description of this species and regard the species name to be identical to C. pilosellae , with which we here synonymise it.

We have not studied specimens of Puto jarudensis Tang described from China on Kalimeris integrifolia (Asteraceae) . The description and illustration given by Tang (1992), however, leaves little doubt that the species is identical to C. pilosellae . Tang (1992) points out that P. jarudensis has two sizes of tubular ducts, with larger ones mainly in the ventral median areas of the head and thorax, and smaller ones on the ventral abdomen. Although existing descriptions of C. pilosellae ( Danzig, 1980; Kosztarab & Kozár, 1988; Marotta & Tranfaglia, 1993) do not provide details of the size of the ventral ducts, the specimens of C. pilosellae from Europe that we have examined have larger tubular ducts on the head and thorax than those on the abdomen, in agreement with Tang’s description of P. jarudensis .
