A total of 296 species of Miridae belonging to 17 tribes were recorded from State of Minas Gerais, Brazil. New host plant records include 141 species of 43 orders and 69 families. Of this total, 98.5% of plants have some agricultural, pharmacological or ornamental importance; 29 orders and families of host plants have two or more mirid species.

Leptophlebiidae ocorrentes no Estado do Rio de Janeiro, Brasil: hábitats, meso-hábitats e hábitos das ninfas (Insecta: Ephemeroptera)

A familia Leptophlebiidae e ainda pobremente conhecida no Estado do Rio de Janeiro, tanto em termos faunisticos quanto taxonomicos e biologicos. No presente trabalho foram reunidos dados biologicos acerca de 14 generos (Askola, Farrodes, Hagenulopsis, Hermanella, Hylister, Leentvaaria, Massartella, Miroculis, Needhamella, Perissophlebiodes, Thraulodes, Traverella e Ulmeritoides, alem de um genero ainda nao descrito) e em torno de 25 morfoespecies ocorrentes no estado. Em termos ecologicos, a maioria dos generos e especies dessa familia esta associada a ambientes loticos ritrais, colonizando areas de deposicao de material orgânico aloctone.

Flutuação populacional de Agallia incongrua Oman, 1938 (Hemiptera: Cicadellidae) em Viçosa, Minas Gerais, Brasil

Population fluctuation of Agallia incongrua Oman, 1938 (Hemiptera: Cicadellidae) in Vicosa, Minas Gerais, Brazil. Based on light-trap collections from 1986 to 1988 at Mata do Paraiso, Vicosa county, Minas Gerais State, Brazil, annual fluctuations of the leafhopper Agallia incongrua Oman, 1938 were studied. Fluctuations in the population were positively correlated to mean temperature. No significant correlations between the species fluctuations and the rainfall patterns were observed. The population pattern of A. incongrua during the wet season was not different from that of the dry season at Mata do Paraiso.

A New Species of Dikrella Oman, 1949 (Hemiptera: Cicadellidae: Typhlocybinae) Found on Caryocar brasiliense Cambess. (Caryocaraceae) in Minas Gerais State, Brazil

A new species of Dikrella is described and figured based on specimens from Minas Gerais, Southeastern Brazil. The new species is diagnosed by the process of pygofer and the general form of aedeagus. Adult males, females, and also nymphs were found on pequi tree, suggesting that Dikrella caryocar n. sp. has its full life cycle in this plant.

A new species of Agallia Curtis, 1833 from Southeastern Brazil (Insecta: Hemiptera: Cicadellidae: Agalliinae) with taxonomic notes on the genus

A new species of Agallia Curtis is described and illustrated from Southeastern Brazil (Minas Gerais State). Agallia catiae sp. n. can be distinguished by its male pygofer, which presents on posterior margin a dorsally directed triangular lobe and on ventral margin a conspicuous elongate process with apex expanded and directed inwards. The taxonomic problems currently affecting the genus Agallia are briefly presented. The ovipositor valvulae of the new species are described and compared with those of other Agalliinae taxa, including the type species Agallia consobrina Curtis. In order to facilitate the identification of female specimens from this subfamily, it is proposed that, whenever possible, taxonomists should treat the female genitalia in detail in descriptions of new taxa or redescriptions.

Two new species of Scaris le peletier & serville (Homoptera, Cicadellidae, Gyponinae) from Brazil

Scaris bahiensis, sp.n. is described based on an adult male from Bahia. It is not closely related to any species of its genus. Scaris nessimiani, sp.n., related to S. defecta DeLong & Freytag, 1969, is described based on an adult male from Mato Grosso.

On the female of Gypona reversa DeLong & Martinson, 1972, with emphasis on genital structures (Insecta: Hemiptera: Cicadellidae)

Abstract Gypona reversa DeLong & Martinson, 1972 has its ovipositor described and illustrated based on the examination of specimens from its type locality. This is the first species of Gypona Germar, 1821 to have the female genitalia detailed description published.

A new species of Pachyopsis Uhler (Homoptera: Cicadellidae: Iassinae) from Southeastern Brazil

A new leafhopper, Pachyopsis vicosensis n.sp., is described from state of Minas Gerais, Brazil. The new species is more closely related to P. foratus Kramer.

Two new species of genus Joruma McAtee (Hemiptera: Cicadellidae: Typhlocybinae) from Viçosa, Minas Gerais State, Brazil

Joruma abernardesi sp.nov. and Joruma phrolfsi sp.nov. (Typhlocybinae: Jorumini) are described based on specimens from Mata do Paraíso, an Atlantic Forest reserve located at Viçosa municipality. This is the first record of the genus Joruma McAtee in Minas Gerais State, southeastern Brazil.

Three New Species of Curtara (Homoptera: Cicadellidae: Gyponinae) from Brazil

Three new species of the leafhopper genus Curtara DeLong & Freytag, 1972, C. mejdalanii spec. nov., C. maricaensis spec. nov., and C. restingalis spec. nov., are described from Rio de Janeiro State, Brazil. They belong to the Notanda group of the subgenus Curtara because of the presence of only two subapical processes in the aedeagal shaft. C. mejdalanii spec. nov. seems to be more closely related to C. rugara DeLong & Freytag, 1976 because of the shape of the subapical aedeagal processes but differs from it by the enlarged apical area of the aedeagus, the absence of ventral pre-apical saliency of style, the rounder apex of the subgenital plate, and the longer pygofer, with a fold accompanying the whole lateral margin. C. maricaensis spec. nov. and C. restingalis spec. nov. seem to be closely related to C. esona DeLong & Freytag, 1976, as suggested by the general shape of internal genital parts, but differ from it by the shape of the apex of basal processes of the aedeagus, the apex of subgenital plates and the absence of an outer fold on the ventral margin of the pygofer.
