Abstract

Two mealybug species (Hemiptera: Coccomorpha: Pseudococcidae), Pelionella osakaensis sp. n. and P. manifecta (Borchsenius, 1949), are described and illustrated based on adult female specimens collected in Japan, on the Japanese mugwort Artemisia indica Willd. var. maximowiczii (Nakai) H. Hara (Asteraceae). These are the first records of the occurrence of Pelionella species in East Asia. The new species is similar to P. grassiana (Goux, 1989) and P. proeminens (Goux, 1990), but differs in lacking multilocular pores with double loculi rings on the venter and in possessing dorsal cerarii and a circulus. The Japanese population of P. manifecta is morphologically slightly different from the Azerbaijani and French populations in lacking large-type oral-collar tubular ducts associated with clusters formed by multilocular pores and oral-collar ducts on ventral abdominal segments III and IV. A modified key to species of the genus Pelionella Kaydan, 2015, is provided.
