ABSTRACT
We describe here two new species of the genus Phalangopsis Serville, 1831 from the Brazilian Amazon Forest. The male genitalia and the female copulatory papilla were described, and a combination of diagnostic characteristics was given to separate both new species from the other described species. The principal morphological characteristics of this genus were discussed.
Aqui foram descritas duas espécies novas do gênero Phalangopsis Serville, 1831 da Floresta Amazônica brasileira. A genitália masculina e a papila copulatória feminina são descritas, bem como uma combinação de características diagnósticas para separar ambas as novas espécies das outras espécies descritas. As principais características morfológicas foram discutidas.

The genus Laranda has six described species and is confined to South and Southeast of Brazil. We describe a new species and discuss the biology and distribution of the genus. The new species can be distinguished from its known congeners by the following characteristics: absence of yellow spots on pronotum and base of posterior tibiae; female copulatory papilla: sclerotization in dorsal view forming opposing acute angles, apical lobes narrow and small; male genitalia: pseudepiphallic median process short and wide; pseudepiphallic paramere with apex incurved and ectophallic fold surpassing apex of the parameres. The genus is distributed within the Atlantic Forest biome; the new species is found on tree trunks, as well as on forest leaf litter.

O gênero Laranda possui seis espécies descritas e está confinado ao Sul e Sudeste do Brasil. Neste trabalho é descrita uma nova espécie, e a biologia e a distribuição do gênero são discutidas. A nova espécie pode ser distinguida das demais espécies do gênero pelas seguintes características: ausência de manchas amarelas no pronoto e base das tíbias posteriores; papila copulatória da fêmea: esclerotização em vista dorsal formando ângulos agudos opostos e lobos apicais estreitos e pequenos; genitália do macho: processo mediano do pseudepifalo curto e largo; parâmero pseudepifálico com ápice curvado e dobra ectofálica ultrapassando o ápice dos parâmeros. O gênero se distribui dentro do bioma Mata Atlântica; a nova espécie é encontrada sobre troncos de árvores, bem como sobre serrapilheira florestal.

The aim of our study was to characterize Cerataphis brasiliensis Hempel, an aphid of native palm tree of tropical savannas (cerrado), and to record intraspecific variation. We found two parthenogenetic forms of apterous viviparae females of C. brasiliensis. We differentiate the two forms through measurable and qualitative characters: (i) length of cephalic horns, (ii) number of antennal segments, (iii) presence or absence of wax glands, (iv) location of siphunculi.

O objetivo desse estudo foi caracterizar Cerataphis brasiliensis Hempel, um afídeo de palmeiras nativas de savanas tropicais (cerrado), e registrar a variação intra-específica. Foram encontradas duas formas de fêmeas partenogenéticas viviparas ápteras de C. brasiliensis, diferenciadas por caracteres mensuráveis e qualitativos: (i) comprimento dos chifres cefálicos, (ii) número de segmentos da antena, (iii) presença ou ausência de glândulas de cera, (iv) localização do sifúnculo.
