Description of the pupa of Lopesia brasiliensis Rübsaamen (Diptera, Cecidomyiidae) Descrição da pupa de Lopesia brasiliensis Rübsaamen (Diptera, Cecidomyiidae)

Lopesia brasiliensis Rübsaamen, 1908 was described as male, female and larva, based on material from the States of Rio de Janeiro and Santa Catarina (Brazil). This cecidomyiid induces leaf galls on Ossaea sp. (Melastomataceae). The pupa is described and illustrated for the first time.<br>Lopesia brasiliensis Rübsaamen, 1908 foi descrita como macho, fêmea e larva, com base em material dos Estados do Rio de Janeiro e Santa Catarina (Brasil).

The gall midges (Diptera, Cecidomyiidae) from three restingas of Rio de Janeiro State, Brazil

One hundred and eight species of Cecidomyiinae (Cecidomyiidae) were found in association with 53 species of plant distributed among 42 genera and 32 families at restingas of Barra de Maricá, Itaipuaçu and Carapebus. Ninety four gall midge species were cecidogenous, four predaceous, five inquilinous of galls and five were free living. Galling species were associated with 47 plant species belonging to 36 genera and 28 families. The majority of the galls occurred on the leaves (N = 63); 13 on buds; nine on inflorescence, closed flower or flower peduncle; three on fruits and one on tendril. Myrtaceae were the richest plant family in number of galls followed by Burseraceae, Nyctaginaceae, Sapotaceae, Erythroxylaceae, Malpighiaceae and Solanaceae. New records of host plants and localities were recorded. Seventy nine Cecidomyiinae species were found at Restinga of Barra de Maricá, 64 at Carapebus and 41 at Itaipuaçu. Sorensen's index revealed that the restingas of Barra de Maricá and Itaipuaçu ate more similar in Cecidomyiinae fauna, confirming a positive relation between geographical proximity and fauna similarity
