Pseudococcidae
We have been unable to find a description of the field characteristics of this species in the literature. Based on characteristics of slide-mounted adult female: Body broadly oval; ovisac covering posterior tip of dorsum and present on venter; 18 pairs of thin lateral filaments, posterior pair longer than rest, surrounding body margin; body covered by white mealy secretion. Probably on fruit and stems of host.
Oral-collar tubular duct present on dorsal surface of abdomen; largest discoidal pores slightly smaller that diameter of multilocular pores; sclerotized plate next to eye with several large discoidals; antennae 9-segemented; 18 pairs of cerarii; large oral-collar tubular ducts forming ventral band around body margin; translucent pores on hind coxa, trochanter, femur, and tibia; dorsal setae conical
Hordeolicoccus heterotrichus is similar to H. invocatus Williams and H. nephelii Williams by having 18 pairs of cerarii; sclerotized plate with discoidal pores near eye; ventral multilocular pores confined to abdomen; translucent pores on hind coxa, trochanter, femur, and tibia. Hordeolicoccus heterotrichus differs from H. invocatus and H. nephelii by having dorsal oral-collar tubular ducts which are absent on the latter species.
This species was intercepted 5 times at U. S. ports-of-entry between 1995 and 2012, with specimens originating from Japan, Thailand and Vietnam, on Nephelium. We also have examined specimens taken at U. S. ports-of-entry from Cambodia, Indonesia, Singapore, Thailand and Vietnam on Garcinia and Nephelium. ScaleNet lists the species from 8 families of host plants, and distribution records include countries in the Oriental zoogeographic region only. One other species of Hordeolicoccus other than H. nephelii (Takahashi) and H. heterotrichus has been taken at U. S. ports-of-entry, H. invocatus Williams (The Philippines, Thailand, on Nephelium).
