Phenacoccus Cockerell

We have examined several species of Phenacoccus (listed in Table 1) including the type species, Ph. aceris , with particular emphasis on those species with more than two setae in the cerarii.

Diagnosis of adult female. Eye height usually shorter than first antennal segment; antennae usually with 8 or 9 segments, but sometimes with as few as 6; 0–2 antennal intersegmental sensilla present between segments VI– VII, absent between segments III–IV, IV–V; 2 campaniform sensilla on each surface of each trochanter; claw lacking basal spurs; claw digitules capitate but tarsal digitules simple; 18 or fewer pairs of cerarii; tubular ducts usually absent on frons; trilocular pores on venter smaller than those on dorsum, dorsal and cerarian pores approximately equal in size; quinquelocular pores usually present. First-instar nymph: 6-segmented antennae; multilocular pores with>5 loculi absent. Adult male: head with one pair of dorsal and one pair of ventral simple eyes plus lateral ocelli; 2 pairs of lateral filaments on posterior abdominal segments (each filament from glandular pouch on each side of abdominal segments VII and VIII); penial sheath apparently 2-segmented, apex of aedeagus simple and slightly rounded or pointed ( Beardsley 1960, 1962; Miller & Appleby, 1971; Hardy et al. 2008; Hodgson et al., 2008).
