Alien invasive species pose major economic and environmental threats that affect ecosystems, human health and economies1–3. Of all the invaders, insects are highly successful due to their ability to escape detection, rapid reproduction and quick dispersal4. Diaspididae, the armoured scales, constitute the largest family within Coccoidea, the superfamily of scales and mealybugs. The family comprises 2695 named species placed in 417 genera5. They include many economically important pest species of forest, fruit and ornamental crops through-out the world, and are among the most common species found on imported plant products6. The genus Aulacaspis Cockerell, 1893 is represented by 151 species globally5. Varshney7 has listed 20 species of Aulacaspis from South Asia. The invasive Aulacaspis crawii (Cockerell, 1898), native to Asia, was described from specimens intercepted at the San Francisco port, USA, in wood imported from China8. Now distributed in 16 countries in Africa, Asia, Europe and North America, A. crawii has been recorded on 18 species in 16 genera belonging to 13 plant families5. Commonly called ‘azedarach scale’, A. crawii is so far not known from India, though García Morales et al. 5 have erroneously mentioned its occurrence in the country and wrongly attributed the same to Giliomee9. However, Giliomee9 deals with African fauna and there is no mention of A. crawii occurring in India. Varshney’s7 catalogue also does not mention its occurrence in India.
