Common name

Odermatt mealybug

Field characters

According to Tokihiro (2004) this species has: body oval; slightly rounded in lateral view; with dark dorsosubmedial bare spots on intersegmental areas of thorax and abdomen, these areas forming 1 pair of dark longitudinal lines on dorsum; with 17 pairs of lateral filaments; posterior pair longest, about 1/2 as long as body. Based on the morphology of the adult female we suspect that the ovisac covers the dorsum. On foliage and fruit of host.

Validation characters

Dorsal oral-collar tubular ducts present; dorsal setae elongate, nearly as long as ventral setae; translucent pores present on hind femur and tibia, absent from coxa; without discoidal pores near eye; ventral oral-collar tubular ducts in small numbers along body margin of head and thorax.


Pseudococcus odermatti is similar to P. comstocki and P. apodemus Williams by having dorsal oral-collar tubular ducts and long dorsal setae, but differs by lacking translucent pores on the hind coxa. Pseudococcus comstocki and P. apodemus both have translucent pores on the hind coxa.
