Validation characters

Oral-rim tubular ducts restricted to venter, on dorsum replaced by oral-collar tubular ducts with a narrow rim located on submargin; multilocular pores normally restricted to segment VIII and numbering 3-5 pores, rarely with 1 on segment VII; dorsal setae elongate, mostly more than 100μ long; vulva saccate, with 4 ducts; translucent pores present on hind femur and tibia; oral-collar tubular ducts usually absent laterad of anterior spiracle; 17 pairs of cerarii with auxiliary setae.

Comparison

Pseudococcus philippinicus is similar to P. trukensis Beardsley by having multilocular pores restricted to abdominal segment VIII, translucent pores on hind femur and tibia, vulva saccate, 17 pairs of cerarii. Pseudococcus philippinicus can be distinguished (characters of P. trukensis are in parentheses) by lacking dorsal oral rims (present), having much longer dorsal setae (short), and having many ventral oral rims near body margin of thorax and abdomen (few or absent).
