The type material of six species of Porricondylinae (Diptera: Cecidomyiidae) described from the Neotropical Region between 1905 and 1936 is re-examined. On the basis of revised adult descriptions the classification of these species is analyzed and discussed. Lectotypes are designated for Asynapta citrinae Felt, A. mangiferae Felt, Holoneurus occidentalis Felt, and Porricondyla gossypii Coquillett.

Abstract Ozognathus cornutus (LeConte, 1859) (Coleoptera: Ptinidae: Ernobiinae), species native to North America, is a saproxylophagous and known feed on decaying tissues within conspicuous galls vegetal organic material such as dried fruits or small wood shavings insect excrements in galleries made by other woodboring species. A few years after the first record 2011, its naturalization Italy h...

We report for the first time conical galls of Clinodiplosis capsici Gagné, 2000 (Diptera, Cecidomyiidae) on sweet pepper ( Capsicum annuum L., Solanaceae) in Brazil. This has agricultural importance since this midge is one known sweet-pepper pests.

Four new genera belonging to the tribe Dasineurini (Diptera: Cecidomyiidae: Lasiopteridi) are described for previously incorrectly placed species. The new genera are: Cembrotia Gagné, type species Janetiella coloradensis Felt; Cupressatia Gagné, type-species Janetiella siskiyou Felt; Strobilotia Gagné, type species Phytophaga carpophaga Tripp; and Rhizocecis Gagné, type species Cecidomyia rhois...

Two new species of gall midges (Diptera, Cecidomyiidae) Dasineura ovalifoliae and Clinodiplosis maricaensis are described based on material from the Barra de Maricá restinga, Maricá, Rio de Janeiro, Brazil. Both species are associated with Erythroxylum ovalifolium Peyr. (Erythroxylaceae). The former is the gall inducer and the latter an inquiline.

Asphondylia hancorniae, sp. n. (Diptera, Cecidomyiidae) is described and illustrated. This species was collected in Atlantic Forest Caatinga domains Bahia State (Northeastern Brazil). It induces galls on fruits of Hancornia speciosa Gomes (Apocynaceae), a plant native to Brazil. hancorniae compared other congeneric which induce Apocynaceae.

Two new species of Tetradiplosis inducing galls on Prosopis caldenia are described from Argentina: Tetradiplosis panghitruz Martínez n. sp. and Tetradiplosis rayen Martínez n. sp. Tetradiplosispanghitruz induces multilocular galls on vegetative stems, whereas T. rayen induces unilocular galls containing multiple larvae on the rachis of the developing inflorescences. The adult male, female, pupa...

Abstract: An overview of insect galls on Asteraceae in Brazil is presented. We used the Web Science database to find publications about from 1988 2020. analyzed 88 and collected data 51 those. A total 487 gall morphotypes were counted 157 plant species 42 genera. This value singled out as richest family number Brazil. Most recorded Atlantic Forest (41%) Cerrado (30.5%), most surveyed biomes Bac...
