Taxonomy and biology of a new ambrosia gall midge Daphnephila urnicola sp. nov. (Diptera: Cecidomyiidae) inducing urn-shaped leaf galls on two species of Machilus (Lauraceae) in Taiwan.

Description, host range and distribution of a new Macrodiplosis species (Diptera: Cecidomyiidae) that induces leaf-margin fold galls on deciduous Quercus (Fagaceae) with comparative notes on Palaearctic congeners.

A gall midge that induces upwardly folded leaf-margin galls on Quercus serrata, Q. mongolica and Q. dentata (Fagaceae) in Japan and South Korea is described as Macrodiplosis selenis sp. n. (Diptera: Cecidomyiidae). M. selenis is distinguished from Palaearctic congeners by a combination of morphological characters. Genetic differences supported the result of morphological comparison and indicate...

Contarinia manii sp. n. (Diptera, Cecidomyiidae): inducer of a remarkable gall on Acacia ferruginea in southern India

Contarinia manii (Diptera: Cecidomyiidae) is described as a new species, on the basis of adults reared from remarkable 'cylinder-piston' galls formed from contiguous leaflets of Acacia ferruginea D.C. in southern India. These galls have been known since 1952 but adults were not reared until 2007. The new species, and another Indian species, Contarinia ramachandrani (Mani), induce similar but di...

A New Species of Gall Midge (Diptera: Cecidomyiidae) from Subterranean Stem Galls of Licania Michauxii (Chrysobalanaceae) in Florida

Photosynthetic efficiency of Clusia arrudae leaf tissue with and without Cecidomyiidae galls.

Leaf galls induced by a still undescribed new species of Cecidomyiidae (Diptera) are frequent on leaves of Clusia arrudae Planchon & Tirana (Clusiaceae) in the rupestrian fields at 1400 m a.s.l. in Serra do Cipó, Minas Gerais, Brazil. Galls were 7.1 ± 0.7 mm in diameter, one chambered with only one larva inside. Gall tissue is green and soft. Assessments of photosynthetic capacity using chlorop...

Life history of the gall-maker Eugeniamyia dispar Maia, Mendonça-Jr. & Romanowski, 1996 (Diptera, Cecidomyiidae).

The development of the galls of the midge Eugeniamyia dispar Maia, Mendonça-Jr. & Romanowski, 1996 (Diptera: Cecidomyiidae) was monitored weekly on its host plant, Eugenia uniflora (Myrtaceae). The work was carried out in the urban area of Porto Alegre, RS, Brazil, from October 1993 to September 1995. Galls were collected from the field and raised in the laboratory to obtain adults. The females...
