Remarks

• Systematics: Pseudococcus occultus could be confused with P. elisae, which has a similar distribution of tubular ducts with oral rims on the bdorsum, but P. elisae has numerous ventral ducts with oral collars on the thorax, some with an undefined border. In addition, it resembles P. mandio because of the small number of tubular ducts with oral borims on the dorsum. It differs in that P. occultus 1) lacks ducts with an oral collar in the lateral area of the abdominal segments (present in P. mandio); 2) has multilocular pores up to segment IV of the abdomen (up to III and dispersed, scarce in the middle area of the thorax in P. mandio); 3) C6 has three conical setae (C6 with two conical setae); and 4) ventral surface with a duct with oral border in segment I of the abdomen (absent in P. mandio). So far, P. mandio has been found only on Manihot esculenta and P. occultus on roots of Solanaceae. (Granara de Willink & González, 2018.)
• Structure: Translucent pores on the femur and tibia, sometimes absent on the femur; eyes with discoidal pores on membranous surface; a frontal pair of tubular ducts with oral rims, scarce in lateral and sublateral zone of the thorax, submarginal and lateral on the dorsal abdomen; submariginal on segment I of ventral abdomen; multilocular pores up to segment IV and absent on ventral thorax; ducts without collars form groups in frontal zone, near C3, C4, C5 and C6, absent in the rest of the thorax; present on the abdomen, in the middle zone up to segment IV, and submarginal in all segments. (Granara de Willink & González, 2018.)
