A biological and systematic study of Philippine plant galls

Three new species of gall-forming psyllids (Hemiptera: Psylloidea) from Papua New Guinea, with new records and notes on related species

“…The suspected synonymy of this material was noted by Hollis (1984, p. 28), and after examining this material, DMP concurs with his assessment and the synonymy is formalized here. The two galls are spherical and globular, and appear similar to those found on Ficus variegata (Moraceae) from Singapore ( Figure 5E) and the Philippines (illustrated by Uichanco 1919), but they appear to lack exterior trichomes. In addition, there is some uncertainty regarding the host-plant range, as the holotype and paratype series (including BMNH material) was collected 'ex galls on unknown plant', but Mathur (1975) also cites other material collected from West Bengal, India (13 July 1935) ex galls on leaves of Breonia chinensis (= Anthocephalus indicus; Rubiaceae) in his description of P. reticulata.…”

First record of the psyllid Leptynoptera sulfurea Crawford (Hemiptera: Psylloidea: Triozidae) from the Cocos (Keeling) Islands

“…The observations by Tigvatnanont (1991) suggest that L. sulfurea does not form an enclosed gall, and that it is more likely to distort the leaves to provide a shelter for the immatures. Uichanco (1919Uichanco ( , 1921 describes the species as forming galls, while Braza and Calilung (1981) call it a gall-former that rolls up and curls the leaf margins to enclose the immatures inside. They found shed exuviae on the leaf surface suggesting immatures leave the galls for adult emergence.…”

“…Crawford (1919) erected the genus Leptynoptera and described the species L. sulfurea based on one damaged specimen from Amboina (Ambon Island) in the Moluccas Islands (Maluku Islands), Indonesia. Uichanco (1919) published a photograph of marginal leaf galls on C. inophyllum from Luzon (Philippines). Uichanco (1919) stated that adult psyllids were collected at the time but they were not identified to species.…”

“…Uichanco (1919) published a photograph of marginal leaf galls on C. inophyllum from Luzon (Philippines). Uichanco (1919) stated that adult psyllids were collected at the time but they were not identified to species. Later, Uichanco (1921) described these psyllids as a new variety of L. sulfurea rubrocincta and provided illustrations of the forewing, and the male and female genitalia.…”

“…It is a gall-forming psyllid (Uichanco, 1919;Anthony, 1974;Martin and Hollis, 1992). The main reference to the biology of L. sulfurea is from Thailand (Tigvatnanont, 1991).…”
