Studies on Mealybug Species (Hemiptera: Coccomorpha: Pseudococcidae) with Description of Two New Species and Three Newly Recorded Species from Indonesia

Mealybugs (Hemiptera: Coccomorpha: Pseudococcidae) include economically important insect pests worldwide. However, little is known about mealybug species in Indonesia. Scale insects were collected and identified from natural and cultivated plants in several regions of southern Sumatra, Indonesia between 2018 and 2019. In total, 16 species of Pseudococcidae in 7 genera were found, including two new species and three new records for the Indonesian mealybug fauna. Dysmicoccus sosromarsonae Zarkani & Kaydan sp. n., and Dysmicoccus zeynepae Zarkani & Kaydan sp. n. are described and illustrated as new species for science-based on the adult female. Furthermore, Dysmicoccus arachidis Williams and Dysmicoccus carens Williams and Pseudococcus leptotrichotus Williams were found as new records for the country. New locality and host plant data are given for all species. Additionally, an identification key to mealybug genera occurring in Indonesia is also provided.
