RESUMO

A new species of Xenicola Uvarov, 1940 (Orthoptera: Tettigoniidae: Phaneropterinae), X. brauni sp. n., is described from the Atlantic Forest of southeastern Brazil. Morphological comparisons with all other known species of Xenicola are presented and discussed. This is the first record of Xenicola in southeastern Brazil, and is also the northernmost record of the genus within the Brazilian Atlantic Forest.

RESUMO

Abstract Here we describe a new katydid species, Phylloptera jaci sp. nov., from the Iguaçu National Park, a large Atlantic Forest protected remnant in southern Brazil. This is the first record of a species of Phylloptera of the picta species group both for Brazil and the Atlantic Forest. We also designate the lectotype for Phylloptera picta, from Peru, and present a complementary description of this species. An occurrence map for the species of Phylloptera of the picta species group are also presented.

RESUMO

The species of brachypterous Phaneropterinae (Tettigoniidae) inhabiting the Iguaçu National Park, Paraná, Brazil, were studied. Four species have been recognized, Anisophya melanochloris (Rehn, 1911) and three new species described here: Anisophya una sp. n., as well as Xenicola taroba sp. n. and Xenicola xukrixi sp. n. We present relevant characters used in Orthoptera taxonomy, such as male genitalia, male and female stridulatory files, cerci and subgenital plates for all four species. Calling songs of three species are also described. X. xukrixi sp. n. stands out by its high carrier frequency with a peak above 70 kHz.

RESUMO

A new species of the Neotropical grasshopper genus Aptoceras Bruner, 1908 is described from individuals collected in the Iguaçu National Park, Paraná State, Brazil. Aptoceras iguassuensis n. sp. inhabits in shrubs in the Atlantic Forest. The species belongs to the genus group Nicarchae Brunner von Wattenwyl, 1893. Descriptions, photographs, and illustrations of the male and female, as well as photographs of the male phallic sclerites are presented. An identification key for the five species of Aptoceras from Brazil and a distribution map are also given.

RESUMO

A new species of Anaulacomera, A. trispinata sp. n., of the poculigera group is described from the Iguaçu National Park, a large remnant of Atlantic Forest in southern Brazil. This is the first record of the poculigera group both for Brazil and for the Atlantic Forest domain. The overall morphology of both males and females is presented, besides the calling songs of males.

RESUMO

In this study, we describe a new species of the genus Poecilocloeus from Renascença municipality, Paraná State, Brazil. Poecilocloeus renascensis n. sp. inhabits the Atlantic Semideciduous Forest edges of Renascença and adjacent areas, and our study is the first record of this genus from southern Brazil. The species belongs to the group bullatus (Rehn, 1908), and the descriptions are based on morphological characters, mainly from male genitalia. Morphological descriptions are provided together with illustrations emphasizing the most significant diagnostic features of external morphology and male genitalia. Information is given about type specimens, examined material and geographic distribution.

RESUMO

For insects, choosing a favorable oviposition site is a type of parental care, as far as it increases the fitness of its offspring. Niche theory predicts that crickets should show a bell-shaped oviposition response to substrate moisture. However, lab experiments with mole crickets showed a linear oviposition response to substrate moisture. Studies with the house cricket Acheta domesticus also showed a linear juvenile body growth response to water availability, thus adult ovipositing females should respond positively to substrate moisture. We used a field experiment to evaluate the relationship between oviposition preference and substrate moisture in forest litter-dwelling cricket species. We also evaluated oviposition responses to substrate moisture level in Ubiquepuella telytokous, the most abundant litter cricket species in our study area, using a laboratory study. We offered cotton substrate for oviposition which varied in substrate moisture level from zero (i.e., dry) to maximum water absorption capacity. We used two complementary metrics to evaluate oviposition preference: (i) presence or absence of eggs in each sampling unit as binary response variable, and (ii) number of eggs oviposited per sampling unit as count response variable. To test for non-linear responses, we adjusted generalized additive models (GAMM) with mixed effects. We found that both cricket oviposition probability and effort (i.e., number of eggs laid) increased linearly with substrate moisture in the field experiment, and for U. telytokous in the lab experiment. We discarded any non-linear responses. Our results demonstrate the importance of substrate moisture as an ecological niche dimension for litter crickets. This work bolsters knowledge of litter cricket life history association with moisture, and suggests that litter crickets may be particularly threatened by changes in climate that favor habitat drying.

RESUMO

In this study we describe two new species of cavicolous-straminicolous crickets for southern Brazil. Endecous chape n. sp. and E. naipi n. sp. are sympatric crickets that inhabit the Atlantic Semideciduous Forest of the Iguaçu National Park and adjacent areas. The descriptions were based on morphological characters, mainly from male genitalia and tegmina of adult males. Furthermore, we describe the chromosomes and the calling song of one of the new species, E. chape n. sp., presenting a discussion about the morphology of the phallic complex of Endecous and a distribution map for the species of the genus. The type-material is deposited in the Museu de Zoologia da Universidade de São Paulo (MZSP), and in the Coleção de Insetos do Departamento de Zoologia (Zoology Department Insect Collection), Universidade Estadual Paulista-UNESP-Botucatu campus.
