RESUMO
Four species of soft scale insect [Hemiptera: Coccidae: Fistulococcus pokfulamensis Hodgson & Martin, Kilifia deltoides De Lotto, Maacoccus piperis (Green) and Paralecanium machili Takahashi] and two species of mealybug [Hemiptera: Pseudococcidae: Antonina thaiensis Takahashi and Formicococcus simplicior (Green)] are recorded in India for the first time. Each of the six species is comprehensively diagnosed based on Indian material, and compared with earlier descriptions. Keys to the Indian species in their respective genera are provided to facilitate identification. Ecological information on host plants, associated ants and natural enemies is also given.

The notoriously destructive and invasive soft scale, Ceroplastes cirripediformis Comstock (Hemiptera: Coccomorpha: Coccidae), is recorded for the first time from India. The scale is redescribed to facilitate its identification and information on its host range, natural enemies and distribution is provided. An identification key to the Indian species in this genus is given. Management options in the event of an outbreak are discussed briefly. The establishment of this scale insect warrants special attention in India as it is a potentially damaging plant pest and has a broad host range across many plant families.

Invasive species threaten the ecological and economic wellbeing of a country (Pimentel et al. 2001). In the last decade, several mealybugs and soft scale insects have been accidentally introduced to India, of which some have become serious pests (e.g., Phenacoccus solenopsis Tinsley, Paracoccus marginatus Williams Granara de Willink, Phenacoccus madeirensis Green and Pseudococcus jackbeardsleyi Gimpel Miller); others are widening their host ranges and spreading rapidly. Kilifia acuminata (Signoret) and Protopulvinaria longivalvata Green seem relatively harmless but Trijuba oculata (Brain) and Pulvinaria urbicola Cockerell cause economic damage (Joshi Rameshkumar 2013; Joshi 2017).
