RESUMO
BACKGROUND: A gall midge species (Diptera: Cecidomyiidae) inducing leaf bud galls on Magnolia kobus DC. var. borealis Sarg. (Magnoliaceae) was found in Hokkaido and northern Honshu, Japan. NEW INFORMATION: Based on its morphology, the species is regarded as an undescribed species of the genus Pseudasphondylia Monzen (Cecidomyiinae, Cecidomyiidi, Asphondyliini). The species is herein described as Pseudasphondylia saohimea Matsuda, Elsayed and Tokuda sp. n. The new species is easily distinguishable from its congeners by the number of adult palpal segments and the shape of the male terminalia and larval spatula.
RESUMO
Two new species of Schizomyia Kieffer (Diptera: Cecidomyiidae: Asphondyliini: Schizomyiina) are reported from Japan. Schizomyia broussonetiae Elsayed Tokuda n. sp. forms hairy globular leaf galls on the paper mulberry Broussonetia papyrifera (L.) Vent. (Moraceae) and S. uechiae Elsayed and Tokuda n. sp. induces red flower bud galls on the porcelain berry Ampelopsis glandulosa var. brevipedunculata (Maxim.) Momiy. (Vitaceae). Morphological features of larvae, pupae and adults of the new species are described, illustrated and compared in detail to several other Schizomyia species. An updated taxonomic key to known Japanese species of Schizomyia is provided.

BACKGROUND: The genus Pseudasphondylia (Diptera: Cecidomyiidae: Asphondyliini: Asphondyliina) comprises ten Palearctic, Oriental and Australian species associated with various hosts belonging to at least ten plant families. NEW INFORMATION: A new species, Pseudasphondylia tominagai Elsayed & Tokuda n. sp., that induces flower bud galls on Eleutherococcus spinosus (L.f.) S.Y.Hu (Araliaceae) is described. This species is considered to alternate between host plants seasonally. A key to males of known Pseudasphondylia species is provided.
RESUMO
We describe a gall midge Macarangamyia itiokai Elsayed Tokuda gen. n., sp. n. belonging to the subtribe Schizomyiina (Diptera: Cecidomyiidae: Asphondyliini) inducing petiole galls on Macaranga bancana (Miq.) in Lambir Hills National Park, Borneo, Malaysia. The new genus is distinguishable from all known genera of Schizomyiina by the unique dorsally-placed aedeagus slit, the short, membranous, protrusible ovipositor, with scattered strong setae ventrally and dorsally, and the presence of spiracles on all larval thoracic segments. It is compared and separated from its closely related Oriental genera of Schizomyiina.
