Varshney, R.K. 2005 Coccid insects in the western Shivalik Himalaya and adjacent areas (Insecta: Hemiptera: Coccoidea).. Records of the Zoological Survey of India 105(3-4): 141-168.
Notes: Altogether 27 species (plus 5 mentioned in Remarks) belonging to 22 genera and 7 families, have been reported from Western part of the Shivalik Himalaya and adjacent areas in Northern India, covering the Indian States of Jammu & Kashmir, Himachal Pradesh and Punjab. Some taxonomic citations, distribution in India and host plants are mentioned in each case. San Jose scale (Quadraspidiotus perniciosus) is the earliest known and prominent species. Nine species are known from their original records only, mostly from Himachal Pradesh. One species, Aspidiotus theae, though earlier claimed to occur in Kangra, is not included here, since its host plant (tea) does not occur in this region. Two genera, Humococcus and Drepanococcus, have been reported for the first time here in Indian coccid literature.
