Varshney, R.K. 2003 Status of taxonomic aspects of the Lac insects of world.. Bionotes 5(1): 22-23.

Notes: This paper enumerates the factors contributing to the erroneous classification of some lac insects (such as using the family name Kerriidae instead of Tachardiidae, persistently using some invalid or erroneous species names, giving credit to the wrong taxonomic authors, the inability to trace some type specimens of most of the older species, and existence of dubious records) and mentions the taxonomic tools used to differentiate various populations, subspecies and species. The last new genus added, Albotachardina (from China), and the last new species added, Kerria sharda (from eastern India), are noted. Data on the geographical distribution and number of lac insect species in the world are tabulated.
