Takagi, S. 1995 A new species of Beesonia with larval polymorphism, inducing a stem gall on Shorea curtisii in Singapore [Homoptera: Coccoidea: Beesoniidae].. Insecta Matsumurana (New Series) 52: 1-19.

Notes: Description on the basis of larval forms purported to belong to four ontogenetic courses; larval polymorphism is believed to be associated with exploitation of more than a single feeding site provided by the gall's structure; the five known species of the Beesoniidae induce galls on dipterocarps or oaks -- an unexpected combination of host plants from the viewpoint of plant phylogeny.
