Abstract
Lac insects include astonishing species responsible for lac production. Lac is composed of resins, dyes, and shellac wax with significant economic importance. Previously, 11 species of the genus Kerria were reported from China, with the highest species diversity in Yunnan province. Another lac-producing species of the genus Kerria, namely Kerrianepalensis Varshney, is recorded for the first time in Yunnan province, China, on Dalbergiacochinchinensis Pierre ex Laness. (Fabaceae), a new host plant. In addition, a key to the 12 Kerria species recorded in China is also given.

Summary
Scale insects (Hemiptera, Coccoidea) are classified into 35 extant families, with more than 8300 described species to date (García Morales et al 2016). More than 20 species of Kerria have been described and recorded from India, Myanmar, Nepal, Pakistan, and Thailand. Ber (Ziziphus mauritiana Lam.: Rhamnaceae), Kusum (Schleichera oleosa Lour.: Sapindaceae), and Palas (Butea monosperma Lam.: Fabaceae) are the common host plants for the production of lac in India (Bhatnagar et al 2020), whereas Acacia catechu Willd., A. nilotica Willd. Bhutan, Cambodia, China, India, Chen et al 2011, 2013; Varshney and Myanmar, Nepal, Thailand, Tibet, Vietnam. Indonesia, Malaysia, Myanmar Varshney 1976; Chen et al 2013, 2011; 23 Kerria rangoonensis (Chamberlin, 1925)
