﻿AbstractParasitic plants have been known to be attacked by insect pests since ancient times. However, little is known about the mealybug (Hemiptera,Coccomorpha,Pseudococcidae) fauna associated with them. A series of surveys of mealybugs found onLoranthaceae, a semi-parasitic plant family, was conducted in several places in Bengkulu Province, southern Sumatra, Indonesia. In the study, 55 mealybug specimens were collected, consisting of eight species belonging to five genera, namelyChorizococcusMcKenzie (1 species),DysmicoccusFerris (2 species),FerrisiaFullaway (1 species),PlanococcusFerris (3 species) andPseudococcusWestwood (1 species).ChorizococcusozeriZarkani & Kaydan,sp. nov.is new to science, whilstPlanococcusbagmaticusWilliams represents the first record in Indonesia. In addition, the mealybugsDysmicoccuslepelleyi(Betrem),DysmicoccuszeynepaeZarkani & Kaydan,Ferrisiadasylirii(Cockerell),Planococcuslilacinus(Cockerell) andPseudococcusjackbeardsleyiGimpel & Miller are newly recorded from plants of the familyLoranthaceae. Figures and illustrations of mealybug species with a taxonomic key to AsianChorizococcusand a new country record based on morphological characters are also updated.
