Remarks

• Systematics: Pseudococcus eriocerei is similar to P. viburni but differs by having: 66(42-84) trilocular pores on venter of segment VI; 2(1-4) ventral oral-collar tubular ducts mesad of cerarius 12; 2(0-5) ventral oral collars associated with cerarii 10 and 11; 2(1-3) cisvulvar setae; longest interantennal seta 77(40-99)µ long; antennae 411(341-452)µ long; cerarius 12 with 1 (0-3) auxiliary setae and 10(5-15) trilocular pores; 19(0-42) translucent pores on hind femur; tarsus 93(79-104)µ long; longest seta on hind trochanter 99(82-114)µ long. Pseudococcus viburni has: 154(132-200) trilocular pores on the venter of segment VI; 10(8-16) ventral oral collars mesad of cerarius 12; 1(0-2) oral collars associated with cerarii 10 and 11; 4(3-5) cisvulvar setae; longest interantennal seta 102(73-134)µ long; antennae 509(456-585)µ long; cerarius 12 with 3(2-4) auxiliary setae and 19(15-23) trilocular pores; 65(15-150) translucent pores on the hind femur; tarsus 122(114-142)µ long; longest seta on hind trochanter 144(108-157)µ.long. (Gimpel & Miller, 1996)
• Structure: With 19(0-42) translucent pores on hind femur; 2(1-4) oral-collar tubular ducts mesad of cerarius 12; 2(0-5) oral collars associated with cerarii 10 and 11; 1(0-3) auxiliary setae and 10(5-15) trilocular pores in cerarius 12; antennae 411(341-452)µ long; femur 239(217-267)µ long. (Gimpel & Miller, 1996)
• Biology: Williams & Granara de Willink (1992) suggested that it appears to be confined to cacti of the Cereeae group. Occurring on the roots of the host plant.
• General Remarks: Good description and illustration of the adult female given by Williams & Granara de Willink (1992) and by Gimpel & Miller (1996).
