We evaluated the relation of cricket species richness and composition with forest regeneration time, evaluating canopy and litter depth as environmental drivers. Effects of forest patch area, nearest distance to the 300-year patch, cricket abundance, sampling sufficiency, and nestedness were also evaluated. We collected 1174 individuals (five families, 19 species). Species richness increased asymptotically with regeneration time and linearly with canopy cover and litter depth. Canopy cover increased linearly, while litter depth increased asymptotically. Richness was not affected by patch area and nearest distance to the 300-year patch. Richness increased with cricket abundance, and this explanation could not be distinguished from regeneration time, evidencing collinearity of these two explanatory variables. Rarefaction curve slopes increased with regeneration time. Species composition differed among patches, with no nested pattern. We suggest that regeneration and consequent increases in canopy and litter promote recovery of cricket biodiversity, abundance, and changes in species composition. We conclude that the recovery of cricket diversity involves an increase along the spatial scale of complementarity, together with a change in species composition.

Phalangopsidae is the cricket's family with highest species diversity in the Brazil. The aim of this study was to describe one new species of Izecksohniella, and two new Brazilian unspecific genera related to it. Marliella titai gen. nov. et sp. nov. and Joadis mesai gen. nov. et sp. nov. were characterized by genitalia morphology, reduced wings, presence of metanotal and phallic glands. ResumoPhalangopsidae é a família de grilos com a maior diversidade de espécies no Brasil. O objetivo deste estudo foi descrever uma nova espécie de Izecksohniella e dois novos gêneros brasileiros monoespecíficos relacionados a ela. Marliella titai gen. nov. et sp. nov. e Joadis mesai gen. nov. et sp. nov. foram caracterizados pela morfologia da genitália, asas reduzidas, presença de glândulas metanotais e glândulas fálicas.Palavras-Chave: Izecksohniella, genitália masculina, genitália feminina, glândula metanotal

This study describes three new Guabamima species and two new species of the new genus from Atlantic Forest remnants. Mellopsis doucasae gen. nov. was characterized by genitalia morphology, reduced wings, absence of phallic vesicle and glandular hairs on the internal face of the forewing.Este estudo descreve três espécies novas de Guabamima e duas espécies novas de um novo gênero de remanescentes de Mata Atlântica. Mellopsis doucasae gen. nov. foi caracterizado pela morfologia da genitália, asas reduzidas, ausência de vesículas fálicas e de pelos glandulares na face interna da asa anterior.

Um Olhar Minucioso na Variação Intra-Específi ca de Cerataphis brasiliensis (Hempel) (Hemiptera: Hormaphididae)RESUMO -O objetivo desse estudo foi caracterizar Cerataphis brasiliensis Hempel, um afídeo de palmeiras nativas de savanas tropicais (cerrado), e registrar a variação intra-específi ca. 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.PALAVRAS-CHAVE: Afídeo, caráter morfológico, Arecaceae, savana tropical, cerrado ABSTRACT -The aim of our study was to characterize Cerataphis brasiliensis Hempel, an aphid of native palm tree of tropical savannas (cerrado), and to record intraspecifi c 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.

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.

Neotropical Entomology 37(4): 420-425 (2008) Uma Nova Espécie de Laranda Walker 1869 (Orthoptera: Grylloidea, Phalangopsidae) de Remanescentes da Mata Atlântica Brasileira RESUMO -O gênero Laranda possui seis espécies descritas e está confi nado 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 fl orestal.PALAVRAS-CHAVE: Brasil, grilo, distribuição geográfi ca, ninfa ABSTRACT -The genus Laranda has six described species and is confi ned 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.
